Sr. Storage Testing Engineer/Test Specialist,

Cisco Unified Computing System (Cisco UCS) fuses access layer networking and servers. This high-performance, next-generation server system provides a data center with a high degree of workload agility and scalability. Cisco UCS Manager 3.0 supports the Fabric Interconnect that integrates the FI into the UCS Chassis and provides an integrated solution for a smaller deployment environment. The hardware and software components support Cisco's unified fabric, which runs multiple types of data. Center traffic over a single converged network adapter. The simplified architecture of Cisco UCS reduces the number of required devices and centralizes switching resources. By eliminating switching inside a chassis, network access-layer fragmentation is significantly reduced. Cisco UCS implements Cisco unified fabric within racks and groups of racks, supporting Ethernet and Fibre Channel protocols over 10 Gigabit Cisco Data Center Ethernet and Fibre Channel over Ethernet (FCoE) links.

The management and data plane of Cisco UCS is designed for high availability and redundant access layer fabric interconnects.
