Industry Standard innovations that help UCS B-Series Blade servers reduce TCO apply to UCS C-Series Rack-Mount Servers with additional benefits of a familiar rack form factor and built in migration path to Unified Computing.

Unified Fabric – Fabric Extenders

•  Simplify I/O Infrastructure and Management •  Reduce Support Infrastructure up to 50% – Nics, HBA’s, Chassis Interconnects, Cabling

Embedded – Unified Management

•  Single, Highly Available, Point of Management •  Reduce management tools, consoles, modules with full interoperability via XML API

Extended Memory Technology

•  More Economical footprint for memory intensive workloads and higher consolidation ratios. •  Large Dataset workloads on two socket servers.

VN Link – Virtual Interface Card

•  I/O consolidation and increased cpu performance •  Network policy control and transparency to the VM level.

Dynamic Provisioning Service Profiles

•  Faster provisioning - reduced spares •  Enables consistent infrastructure policies w/RBAC
