Executive Overview Successful businesses are defined by efficiency and speed. Companies that use capital more efficiently generate higher profits and have more to invest in future initiatives.

IT is a

critical component of these organizations’ competitive advantage. The back-office functions that provide critical services can no longer afford to be a rigid organization without optimal efficiency. Application-driven virtualization is a way to improve ITs’ speed, efficiency and agility. By deploying Server Virtualization, IT is responding to business requirements to increase agility while at the same time reducing costs and risks from the IT balance sheet. IT becomes much more responsive to the business and through this alignment, a part of the business process. This white paper describes how to implement an Oracle Solution for Virtual Servers with Oracle VM for Small and Medium Business Organizations, leveraging the new Oracle Sun Storage Array 2540-M2. Virtualizing with Oracle VM Server for x86 and taking advantage of unique Oracle tools, businesses can reduce their total cost of ownership in the datacenter more than 25%, increase IT flexibility, and achieve greater business agility. Key benefits are: •

Fully integrated enterprise management from disk to applications to cloud

•

Rapid Enterprise Application Deployment with Oracle VM Templates

•

100+ pre-built Oracle VM Templates ready for deployment

•

All Oracle applications fully certified on Oracle VM

•

Zero licensing cost, affordable enterprise quality support

•

Free to download and distribute

IT organizations often spend multiple weeks to plan, architect, troubleshoot, and deploy a multivendor virtualization infrastructure. Deployment teams must assemble and integrate a range of hardware and software components from different vendors (i.e. servers, storage,

2


network, virtualization software, and operating systems). The process is not only time consuming but also error prone, making it hard to achieve a timely and profitable return on investment. Complex integration models can expose even the most carefully planned deployments to unforeseen risks such as implementation and testing delays, service downtime, costly upgrades, or inefficient system performance. The Oracle Solution for Virtual Servers offers a much simpler approach that speeds deployment and reduces risk. It is a single-vendor solution for both hardware and software stacks. From application to disk, it can be deployed in just one day compared to 10 days using a traditional approach.

Total Cost of Ownership Oracle is the only vendor offering enterprise consolidation solutions for x86-based infrastructures that include built-in virtualization technologies engineered, tested and deployed together as a single system. Because it provides these technologies with high-quality servers, offering a choice of Oracle Linux or Oracle Solaris and a unified service support contract, Oracle can deliver a predictable and easily quantifiable TCO. Oracle provides Ops Center systems management software without charge as part of Premiere Support Option. Coupled with ILOM, the customer gets a robust system management tool that benefits both standalone and cloud system use. While other vendors offer differing system management tools that discourage direct feature by feature comparison, the important thing to remember is that they charge for comprehensive system management; we do not. Oracle offers a Single Support Contact and the testing of bug fixes across the entire stack. With a single support access point, Oracle gets rid of customer time wasted on calling multiple vendors and keeping record of problem ownership. Further, it is common that fixes from one vendor adversely affect another vendor’s products. Oracle, in comparison, tests all our bug fixes against the entire Oracle stack to eliminate these unintended consequences. Taken together, Oracle completely eliminates two of our customer’s most resource intensive activities described above. Oracle offers a Single Management Tool for the entire stack, (i.e.) disk to application. This means that stacks using optional Enterprise Manager with Oracle software and hardware provide higher quality system management information, as layers interact and learn from each other. This also means that system managers using Enterprise Manager are more likely to manage more systems per administrator, a cost savings. Because it offers enterprise consolidation solutions as complete x86 infrastructures and storage, Oracle stands as an exception. The largest cost factors in a standard virtualized x86 enterprise infrastructure quite often arise from having multiple vendors, in the form of software licensing and support costs for Red Hat Enterprise Linux and VMware vSphere, for instance. On a two-socket system, these two costs alone can represent as much as 71 percent of total TCO over a three-year period. Oracle states that its strategy of engineering hardware and software to work together throughout the stack is designed to reduce the complexity that affects time to deploy and support the infrastructure, as well as to reduce the IT cost structure, and to drive efficiencies that reduce TCO across the board. By providing a single point of accountability for the entire system, Premier Support lowers administration costs and reduces costly downtime. This substantially reduces the risks associated with deploying and managing IT systems, as well as providing improved and easily quantified TCO.

Oracle has focused intensively on TCO as it applies to the entire x86/Storage infrastructure stack, designing the major hardware and software components with optimization of performance, management, and TCO as the object from the start. Because these components are created at Oracle by Oracle engineers, they are designed, tested, certified, packaged, deployed, upgraded, managed, and supported together. Oracle can deliver lower TCO in the design and operation of its system, in the ease of deployment enabled by VM Templates and Validated Configurations (eliminating costs for installation and configuration, as well as reducing time to operation and maintenance costs) and in the efficiency and effectiveness of its award-winning Premier Support Package (minimizing costly downtime). Customers have a single point of accountability and assistance for the entire IT stack, which in and of itself, can dramatically serve to lower TCO.

Systems Overview Three HW configurations have been proposed (small/medium/large) in order to start a basic cloud infrastructure with the ability to dynamically scale up as the workload increases, without compromising on the high availability or the performances of the solution. The small configuration consists of one Sun Server X3-2 server for the management (OVM Manager / storage management ―CAM‖ / HW management ―OpsCenter‖), two Sun Server X3-2 (OVM server) and one Sun Storage 2540-M2. Each OVM Server has two HBAs directly attached to the Sun Storage 2540-M2. The medium configuration consists of the previous configuration with a memory upgrade to the OVM Servers and the addition of additional storage capacity to meet the capacity and performance needs. The large configuration consists of the medium configuration with an additional Sun Server X3-2 (third OVM Server), and a storage capacity expansion tray, the Sun Storage 2501-M2. The pictures below illustrate the various components and roles used in this white paper.

Small and Medium configuration

7


Large configuration

The OVM Manager server is responsible for managing the OVM Servers through the OVMnet network. The Storage Management Software, CAM, is also running on this server. The OVM servers are responsible for the running of the Virtual machines (VMs). They are directly connected to the Fiber Channel Storage Array through two redundant HBAs. The Storage array provides connectivity for up to 8 HBAs, or 4 OVM Servers in a fully redundant configuration. For the large configuration, an additional storage expansion tray and a third hypervisor (OVM Server 3) have been added. OVMnet is the Hypervisor Management Network, used by OVM Manager for various functions like: Server Management, Cluster Heartbeat, Live Migrate and storage function that are network based (iSCSI, NFS). For this purpose, any of the four integrated 10GigEth/1GigEth port (NIC 0..3) can be selected to be bounded for the management network. VMnet1 is used for the network traffic between the different virtual machines in a server pool. With the four embedded 10GigEth/1GigEth ports available in any Oracle Sun Server X3-2, various network configurations can be achieved from the OVM Manager console, including any additional NIC card. The various configurations available depend greatly on the customer needs, the available VLANs, and the internal network policies. For more information on network configuration, please refer to the Oracle VM User’s Guide for release 3.1.1, document E27309-02, chapter 5: Managing Networks, available here: http://docs.oracle.com/cd/E27300_01/E27309/E27309.pdf

Oracle VM Concepts and component Oracle VM is an enterprise-class server virtualization solution comprised of Oracle VM Server for x86 and Oracle VM Manager. Oracle VM 3 reflects Oracle’s strategic commitment to deliver Application Driven Virtualization—Virtualization that makes the entire enterprise software and hardware stack easier to deploy, manage, and support so IT and business can be more agile.

Oracle VM concept and components Oracle VM has been designed from the ground-up for excellent scalability, manageability, and ease-ofuse. Oracle VM 3 delivers significant enhancements to make it faster and easier to rollout operating systems, enterprise application and middleware across your entire data center—not just the Oracle software environment—while reducing costs and making your datacenter or cloud environment highly available and secure. Oracle VM Server for x86 is the most scalable x86 server virtualization solution in the market today and it has been tested to handle mission critical enterprise workloads with support for up to 160 physical CPUs and 2 TB of memory (Sun Server X3-8). For virtual machines, Oracle VM 3 can support up to 128 virtual CPUs and 1TB memory per guest VM. Oracle VM supports industry

10


standard x86 operating systems and servers from Oracle and other leading vendors, and it supports a broad range of network and storage devices, making it easy to integrate into your environment. Oracle VM Manager provides an easy-use-centralized management environment for configuring and operating your server, network, and storage infrastructure from a browser based interface (no Java client required) and it is accessible from just about anywhere. Users leverage the virtualization manager for creating management policies, as well as cloning, sharing, configuring, booting and migrating VMs. Oracle VM helps customers improve server utilization, achieve higher availability and achieve better performance while reducing costs. Beyond the virtualization layer, Oracle offers solutions such as Oracle Virtual Assembly Builder, Oracle VM Templates, Oracle Optimized Solution for Enterprise Cloud Infrastructure that leverage Oracle VM and provide application-driven virtualization. With these tools you can: 

Quickly configure and provision entire multi-tier enterprise applications onto virtualized and cloud environments



Deploy a fully configured software stack with preinstalled and preconfigured software images



Save application deployment time by up to 98 percent

Oracle VM 3 supports easy integration with Oracle Enterprise Manager to provide comprehensive management of the full hardware and software stack from applications to disk. Management of the virtual environment can be handled with the many automated features of Oracle VM Manager or a combination of Oracle VM Manager and Oracle Enterprise Manager. In the context of this Whitepaper, OVM can be pre-installed with Oracle x86 HW, or installed when the systems are shipped through the media drives. The Oracle Premium Support for Systems on Oracle x86 Hardware includes Oracle VM support and also Oracle Solaris and Oracle Linux. For more information on OPS for systems, please refer to http://www.oracle.com/us/support/061681.pdf For more information on Oracle VM, please refer to the Oracle VM 3: Architecture and Technical Overview Whitepaper, available here: http://www.oracle.com/us/technologies/virtualization/ovm3-arch-tech-overview-459307.pdf The Oracle VM Datasheet is also available here: http://www.oracle.com/us/technologies/virtualization/ovm-server-for-x86-459312.pdf For more information on how to perform hard partitioning with Oracle VM, please refer to: http://www.oracle.com/technetwork/server-storage/vm/ovm-hardpart-168217.pdf

OVM Templates Oracle VM provides the ability to rapidly and easily deploy a single pre-built, pre-configured, preoptimized and pre-patched guest virtual machine (or multiple machines depending on the application). The guest VM can contain a complete Oracle software solution along with the operating system and related software infrastructure. These guest VMs, called Oracle VM Templates, are available from Oracle’s E-Delivery website and are ready to download and deploy. Already configured for production use, Oracle VM Templates can save users days or weeks learning to install and configure a sophisticated product such as Siebel CRM or Oracle Enterprise Manager Grid Control. Instead, users can simply download and start the VM to begin using it right away. Within these Templates, Oracle software is automatically configured in the same manner as if the software had been installed and patched manually. Accordingly, Oracle VM Templates can also be fully customized post-install and then re-saved as ―golden image‖ Templates in Oracle VM. Such Templates can serve as a user’s enterprise deployment standard to minimize risks and variation across multiple instance deployments. All of the existing Oracle VM Templates that were certified with Oracle VM server 2.x are also certified with Oracle VM Server 3. An application ―assembly‖ is very similar to an Oracle VM Template except that an additional set of configuration information and management policies are packaged along with the set of multiple virtual machines, their virtual disks, and the inter-connectivity between them. These assemblies are packaged using the industry-standard Open Virtualization Format (OVF) for the configuration and policy information. Assemblies can be created as a set of .ovf Open Virtualization Format and disk image (.img) files, or may all be contained in a single Open Virtualization Format Archive (.ova) file. Oracle Virtual Assembly Builder is a sophisticated development tool for introspecting the current application environment and creating assemblies or collections of VMs along with all their critical configuration parameters to allow you to move them to a virtual environment or to replicate easily and quickly within an existing environment. The Oracle VM Guest VM API allows the guest to set/get key/value pairs through the Oracle VM Manager to the virtual machine. The API allows direct integration between guest software and the virtualization layer, to assist in orchestration of complex, multi-VM deployments. An up-to-date list of available Templates can be found on Oracle VM Templates website at www.oracle.com/technetwork/server-storage/vm/templates-101937.html. The Oracle Virtual Assembly Builder datasheet is available here: http://www.oracle.com/technetwork/middleware/ovab/overview/ovab-11116-datasheet1527653.pdf The storage configuration(s) available in the context for this whitepaper provide enough storage capacity to store various OVM templates that can be downloaded from the above link.

EM12c Cloud Control: Metering and Charge back Oracle Enterprise Manager is Oracle’s integrated enterprise IT management product line and provides the industry’s first complete cloud lifecycle management solution. Oracle Enterprise Manager’s Business-Driven IT Management capabilities allow you to quickly set up, manage and support enterprise clouds and traditional Oracle IT environments from applications to disk. Enterprise Manager allows customers to achieve: Best service levels for traditional and cloud applications through management from a business perspective including Oracle Fusion Applications Maximum return on ITs’ investment through the best solution(s) for intelligent management of the Oracle stack and engineered systems. Unmatched customer support experience through real-time integration of Oracle’s knowledgebase with each customer environment Oracle Enterprise Manager is Oracle’s premiere cloud management solution. It is the industry’s first complete solution including self-service provisioning balanced against centralized, policy-based resource management, integrated chargeback and capacity planning and complete visibility of the physical and virtual environment from applications to disk. Enterprise Manager 12c uses the rich monitoring and configuration data that is collected for Enterprise Manager targets as the basis for a metering and chargeback solution. Enterprise Manager Chargeback provides the administrator with: 

Metering for Enterprise Manager targets



Assignment of rates to metered resources



Management of a Cost Center hierarchy



Assignment of resources to Cost Centers



Usage and Charge Reports



Integration with Billing applications

This set of features can be used to implement chargeback in a private cloud. Furthermore, API’s that allow the exporting of metering and charge data to billing solutions such as Oracle Billing and Revenue Management (BRM) provide a solution for the creation of chargeback and billing solutions for public clouds. To use the chargeback capabilities the Oracle Chargeback and Capacity Planning plugin must be deployed on the Oracle Management Server. To begin using Enterprise Manager Chargeback the chargeback administrator needs to enable metering on the Enterprise Manager Targets for which chargeback needs to take place. This is done by adding Enterprise Manager targets into the Chargeback application

Management OVM Manager Management for the Oracle VM environment is provided by Oracle VM Manager, a trans-action-based framework that also includes an integrated database and a web-based management user interface. Oracle VM Manager comes as a SW package to install on a dedicated HW (called OVM Manager server in this Whitepaper). It is also possible to have OVM Manager running on a virtualized environment (as a VM), but this is out of the scope of this document. Oracle VM Manager controls the virtualization environment, creating and monitoring Oracle VM servers and the virtual machines. Oracle VM Manager serves as the only administrative interface to the Oracle VM servers, unlike previous-generations of Oracle VM that were jointly administered from the management server, as well as locally from the command-line for each Oracle VM Server. Oracle VM Manager 3 is an Oracle Fusion Middleware application, based on the Oracle Weblogic Server application server and Oracle Database. The Oracle VM Manager runs on 64-bit Oracle Linux 5.5 OS or later. For its management repository, Oracle VM Manager uses an Oracle Database, which can be installed either on the same management server or a separate server. Oracle Database 11g Express Edition (XE) is bundled with Oracle VM Manager 3 for customer evaluation purposes, but Oracle Database Standard Edition (SE) or Enterprise Edition (EE) is required for production support as the management repository. All necessary licenses, including licenses for Weblogic Server and Database (SE or EE), are included at no additional charge.

15


Oracle VM Manager 3 provide a single GUI in order to: 

discover and manage the HW servers



create Servers pools



create/manage repositories



manage and configure the networks



manage and configure the storage



manage the VMs (create, delete, clone, secure Live Migrate, ...)



setup Virtual CPU scheduling priorities and caps per VM



deploy quickly the Oracle VM Templates



setup Distributed Resource Scheduling (DRS) for capacity management



StorageTek Common Array Manager (CAM) Simple Installation and Management

The Sun Storage Common Array Manager’s (CAM) web-like and task-based management interface significantly reduces the complexity of installation, configuration, management, and diagnostic tasks. Online capacity expansion, data-volume creation, and host-to-volume mappings give users control of their arrays and the ability to make quick changes when necessary. Accessible from anywhere in the world with a secure internet connection, Sun Storage CAM includes automated diagnostics so users can focus on precise, predictable, and repeatable results. Sun Storage Common Array Manager

Common Array Manager (CAM) is web-based management software and is the primary interface for configuring, managing, monitoring, and diagnosing the array. The management software consists of a suite of tools that enable the storage administrator to manage the array both out-of-band over Ethernet and/or in-band using a proxy agent running on a data host which is directly connected to the RAID array (FC or SAS). CAM also offers a scriptable command line interface (CLI) for those desiring it. New arrays are easily registered using the CAM registration wizard. This is done simply by either selecting auto discovery (if the data host is on the same subnet), or by providing the data host’s IP address. Once an array is discovered and registered, management of that array is identical to any outof-band managed RAID array. The management software also provisions and maintains storage for data hosts using storage components that include Storage pools, Storage profiles, Volumes, Virtual disks and Host Groups for easier and quicker application tuning. Snapshots, Volume Copies and Storage Domains are also available as required. With CAM's application driven array management benefits of ease of use, reduced operation costs, quicker deployment time and quick service for maximum uptime, the array is easily upgradable. This ensures zero downtime in OVM configuration migrations from small to medium and from medium to large.

19


Sun StorageTek Common Array Manager The management software provisions and maintains storage for data hosts using these storage components: 

Storage pools are collections of volumes that share a profile defining the common configuration of the volumes.



Storage profiles define the characteristics of a storage pool. You can choose one from the set of pre-configured application aware profiles or create a new one.



Volumes are divisions of a storage pool, consisting of virtual disks, representing the storage space that is used by the data hosts in the environment.



Virtual disks, also called redundant array of independent disks (RAID) sets, are collections of locations in the memory of more than one physical disk. The storage array handles a virtual disk as if it were an actual disk.



Host groups are a collection of hosts that will share access to the same volumes.



Snapshots are point-in-time images of the data in a volume. They offer a high-availability alternative to backups as the array does not need to be taken offline to create the snapshot. Snapshots consume less space than the original data.



Volume copies are copies of the complete contents of one data volume that are located on another data volume on the same array.

20


Storage Domains which allow the array to be partitioned so that only certain hosts have access to volumes. The 2500-M2 support up to 32 Domains. CAM software enables monitoring and diagnostic tasks on the array. You can configure the software to monitor on a 24-hour basis, collecting information that enhances the reliability, availability, and serviceability (RAS) of the array. The management software records alerts and notifications, which can be monitored by displaying the log file. It also automates the transmission of alerts, which can be sent to an email address, to a pager, or to diagnostic software running on a management host on the network. Finally, the management software enables you to run diagnostic tests to troubleshoot problems and access Service Advisor for instruction on replacing field-replaceable units (FRUs). Remote CLI Client

The array can also be managed and configured by using the remote command-line interface (CLI) client. The CLI provides the same control and monitoring capability as the web browser, and it is also scriptable for running frequently performed tasks. The remote CLI client is available for the Solaris operating system (OS) and several other operating systems. Management-Related Service

Management can also be performed using the Hypertext Transfer Protocol Secure (HTTPS) web interfaces for management and monitoring of storage. HTTPS is primarily for web browsers and is protected by passwords and data encryption. The remote command-line interface (CLI) client on a management host is also used for management and monitoring of storage. Managing Arrays

By default, the management host communicates with the arrays out-of-band over Ethernet. This enables you to manage the storage and monitor, diagnose, and fix problems in the array with a browser from any host that has a network connection to the management host. You can also configure in-band management for communication to travel over the data path between a data host and the array. When using out-of-band management, an Ethernet cable connects your management host in the site local area network (LAN) to the array. You have the following options in how you connect the array to the site LAN: 

Dynamic IP address. The array can get its IP addresses from your site’s Dynamic Host Configuration Protocol (DHCP) server each time it logs in to the LAN.



Static IP address. You can set a static IP addresses for the controllers.



Default IP address. You can use default IP addresses for the controllers.



The level of access that the array allows from the network.

You can also manage the array and monitor, diagnose, and fix problems manually with sscs commands or by means of scripts using a remote command-line interface (CLI) client.

The Oracle Sun Storage 2540-M2 Array Hardware and Software components The Sun Storage 2540-M2 was chosen as the array for its modular design, creating an affordable entry point without sacrificing future scalability - enabling customers to start small and grow when they’re required. Dual-active controllers and up to 12 SAS2 drives combine to create a fully-featured and highly available storage system in a 2U enclosure. When capacity and/or performance requirements change, the 2540-M2 Array’s scalability supports up to 84 additional drives for a total of 96 drives. The 2540-M2 Array supports direct attachment of up to eight servers, or provides additional server attachment through FC SAN connectivity. This makes it an ideal solution for businesses that want to initially deploy the 2540-M2 Array as direct attached, and then seamlessly transition to a SAN when necessary. The 2540-M2 Array also combines Oracle’s time-proven designs with advanced front-end 8 Gb/sec FC & 6 Gb/sec SAS2 host connectivity and next-generation SAS2 backend technology to enable organizations productivity through data consolidation, availability, performance, and scalability. Note, that each one of the 6Gbps SAS ports are x 4 ―wide‖, ensuring the creation of 4 lanes in a single connector (24Gbps per SAS port). For performance benefits, our solution benefits from the utilization of 15K revolutions per minute (rpm) SAS2 disk drives within our 2540-M2 arrays. High spindle speeds ensure lower seek times, lower latency and therefore higher disk transfer rates. As mentioned earlier, the 2540-M2 Array dynamically scales both in terms of capacity and performance. A fully configured array supports a maximum of 96 disk drives per system. Typically for IOPS performance, the greater the number of data disks within the array the higher the overall system IOPS performance attained. Throughput however, is not disk drive dependent. For customers where performance is a key criteria, our recommendation is to enable the turbo, or Performance Enhancement feature where applicable. As a rule of thumb, the turbo feature provides performance benefits on arrays exceeding approximately 20 disks in a throughput environment, where the application type is sequential and large block IO. For small block and random application IO, this feature benefits the array exceeding approximately 50 disk drives. The 2540-M2 with its modular capacity and performance scaling architecture is also ideally suited for mixed workload application types and therefore a natural choice for virtualized and scalable needs.

Integrated and Optimized for the Oracle Stack Oracle Optimized Solutions are predefined solutions that integrate the complete application to disk stack so that customers can lower their TCO, mitigate risk and improve productivity and efficiency. The 2540-M2 array is fully integrated into several of these solutions including the World Record TPCH@3000GB benchmark for Oracle Database 11g highlighting the power of the Oracle’s integrated hardware and software solutions.

About Multipathing

With multipathing, also called multipath failover, an array or network can detect when an adapter has failed and automatically switch access to an alternate adapter. Multipathing enables high-availability configuration because it ensures that the data path remains active. Multipathing also helps increase performance to multicontroller disk arrays by spreading I/O between multiple paths into the array. Within the array, storage pools use multipathing by default. To complete the data path, data hosts also need the ability to multipath. For more information about the appropriate multipathing software for your data host, refer to the release notes for the Sun Storage Common Array Manager.

Oracle VM and the 2540-M2 External Storage Oracle has made storage configuration and integration as flexible and modular as possible by creating a Storage Connect plug-in for each different category and type of storage. Storage in Oracle VM refers to two different types of disk storage: the space available for environment resources such as templates and ISO files, and the logical or physical disks used by virtual machines. Note: In addition there is also disk space used for the pool file systems of clustered server pools, but that is not the focus of this section. For virtual machine disks Oracle VM offers you two choices: 

Virtual disks: disk image files on a file system.



Raw physical disks: LUNs accessed directly by the virtual machine.

The design decision of virtual versus physical storage access depends on your server virtualization use cases as well as the existing storage hardware at your disposal. Virtual storage enables quick and easy on-the-fly configuration but introduces a higher level of abstraction. Physical storage access implies that virtual machine disk storage is mapped directly onto the LUNs configured in the physical storage hardware, which is exactly like the way physical servers access their storage. The advantage here is that existing procedures and storage management practices can be maintained. Storage can be configured locally, specifically using an OCFS2 file system on a local disk of the Oracle VM Server. However, it is far more performant and reliable to use a separate location for a storage repository, so that it can be addressed by and attached to all Oracle VM Servers in the server pool. This is also essential for live migration and HA configurations. Storage is configured with any of the following technologies: 

Local disks



Shared Network Attached Storage - NFS



Shared iSCSI SANs: abstracted LUNs or raw disks accessible over existing network infrastructure



Fibre Channel SANs connected to one or more host bus adapters (HBAs)

Note: OCFS2 (Oracle Cluster File System) is used in all these storage configurations except for server pools with no clustering enabled.

29


To enable HA or live migration, you must make sure all Oracle VM Servers have access to the same storage resources. Specifically for live migration the Oracle VM Servers also must be part of the same server pool. Also note that server pools require access to a shared file system where server pool information is stored and retrieved, for example in case of failure and subsequent server role changes. The server pool file system can either be on an NFS share or on a LUN of a storage array. Oracle VM Manager distinguishes between File Servers and Storage Arrays in the Storage tab of the Hardware view. Depending on your hardware and networking configuration, external storage may be detected during discovery of the Oracle VM Servers or a rescan of their physical disks. Local storage is always detected during this discovery operation. An external storage element is created on storage hardware: a server configured for NAS offering NFS shares, generic iSCSI targets and LUNs, or SAN devices, the 2540-M2, for the purpose of this paper. The server or disk subsystem offering the storage simply needs to be reachable by the Oracle VM Servers in the Oracle VM environment through a Fibre Channel or Ethernet network. The external storage is offered as a mount point (NFS share) or LUN (iSCSI and fibre channel) which can be discovered through Oracle VM Manager as a potential location for a repository, or a raw disk for use with a VM. The typical way to attach external storage to the Oracle VM environment is to create a new storage entity in Oracle VM Manager and point to the location of the external storage, the 2540-M2, while selecting the appropriate Storage Connect plug-in. Subsequently, you may choose to configure a storage repository on one or more of the discovered storage entities in order to make storage resources available to servers and server pools in the Oracle VM environment.

Conclusion The Oracle Solution for Virtual Servers for Small and Medium Business Companies addresses one of the key challenges in deploying a virtualization infrastructure while significantly reduces TCO. IT organizations often spend multiple weeks to plan, architect, troubleshoot, and deploy a multivendor solution. Deployment teams must assemble and integrate a range of hardware and software components from different vendors (e.g. servers, storage, network, virtualization software, and operating systems). The process is not only time consuming, but also error-prone, making it hard to achieve a timely and profitable return on investment. The solution described in this white paper offers a much simpler approach for Small and Medium Business Companies that speeds deployment and reduces risk. It is a single-vendor solution for the entire hardware and software stack from application to disk and can be deployed in hours rather than weeks. Validated configurations can significantly reduce testing time as well as the time-consuming effort of determining a stable configuration. IT organizations can take full advantage of the hardware and software components in the described solution realizing greater business benefits from their virtualized infrastructure at a significant reduced TCO compared to other solutions available in the market.

Appendix: JD Edwards Reference Architecture with Oracle VM JD Edwards EnterpriseOne is an integrated application suite of comprehensive enterprise resource planning software that combines business value, standards-based technology, and deep industry experience into a business solution with a low total cost of ownership. A collection of prebuilt Business Intelligence (BI) applications available as modules for JD Edwards EnterpriseOne provide organizations the ability to implement and integrate more quickly, with less risk, and at a fraction of the cost required for building traditional BI solutions. JD Edwards EnterpriseOne provides organizations with the ability to transform information into business actions and enjoy a strategic advantage over less-nimble competitors. Oracle Database 11g Release 2 Standard Edition

Designed for data center environments that are rapidly evolving and changing to keep up with the demands of the business, Oracle Database 11g provides efficient, reliable, and secure data management for mission-critical transactional applications, query-intensive data warehouses, and mixed workloads. With new self-managing capabilities, Oracle Database 11g also eliminates time-consuming, error-prone administrative tasks, so database administrators can focus on strategic business objectives instead of on performance and availability fire drills. Oracle WebLogic Server 10.3.2 Standard Edition

Oracle WebLogic Server Standard Edition is an application server designed for building and running enterprise applications and services. It fully implements the latest Java Platform, Enterprise Edition (Java EE) standards and offers choice in development frameworks and tooling. Comprehensive and accessible management capabilities enable administration of sophisticated systems via a well-designed graphical console and/or automation. All users benefit from Oracle WebLogic Server's reliability and performance, which has been tested over years of enterprise-grade production use in demanding customer environments the world over. JD Edwards EnterpriseOne and Oracle VM Template

JD Edwards EnterpriseOne applications run on top of a robust, flexible, and highly configurable architecture. Various components, such as logic servers, database servers, and web servers cooperate to provide a scalable and configurable technology platform that accommodates enterprises of all sizes, user counts,industries, and geographies. Companies sometimes invest weeks to design, implement, and test the architecture that exactly meets their needs. However, not every implementation of JD Edwards EnterpriseOne requires such rigorous attention during the installation phase. Many customer scenarios can be accommodated by a fundamental configuration on a preconfigured technology stack. Providing a rapid installation of a base configuration, yet allowing for modification, yields the best of both worlds. Oracle VM templates for JD Edwards EnterpriseOne deliver this solution. Oracle VM can encapsulate the complete configuration of a virtual server into a data file (VM template). This template can be used to create a new virtual machine, which then functions exactly as the original virtual machine. Oracle provides a number of predefined templates for its products, which

34


customers can use to rapidly deploy applications and technology products. The picture illustrates this process.

More details can be found here: http://www.oracle.com/technetwork/server-storage/vm/jdedwards-313246.html The graph below shows the JD Edwards Enterprise One Technology Stack with 3-Tier Logical Architecture.

HW Benefits

The Oracle 2540 M2 benefits from the fastest 15K revolutions per minute (rpm) SAS2 electromechanical disk drives. High spindle speeds ensure lower seek times and latency resulting in higher disk transfer rates. A fully configured 2540 M2 with 48 disk drives is capable of delivering 140K Cache read IOPS (22K disk read & 5K disk write) performance. The larger the number of “data” disk drives within the configuration, the higher the IOPS attained. For throughput application needs, a fully populated 2540 M2 is capable of 2.5GBps Cache Read (2.0GBps Disk Read & 1.1GBps Disk Write) performance. The 2540 M2 with its modular capacity and performance scaling architecture is also ideally suited to mixed workload application types and therefore a natural choice for virtualized and scalable needs. The 2540 M2 also benefits from 2 x SAS2 expansion ports. Each one of these ports is 6Gbps SAS x 4 ―wide‖ that ensure the creation of 4 lanes in a single connector (24Gbps per SAS port). This is beneficial for larger configuration requiring one or more 2501 M2 expansion units. Applying Oracle Technology to Deliver True Business Value

Oracle is continually innovating ways to apply its broad portfolio of products to solve real business problems. Oracle VM, OVM templates for JD Edwards, Storage 2540 M2 and Server X3-2, enable customers and partners to realize a rapid return on a small investment by eliminating time, cost, and risk from a JD Edwards EnterpriseOne implementation.
