Compute layer

VxBlock System 1000 includes Cisco UCS 6332-16UP Fabric Interconnects with four or six 40 Gb links connected to a pair of 40 Gb capable Cisco Nexus 9336C-FX2 or 93180LC-EX Switches. Alternatively, the FIs can connect to a pair of 10 Gb capable Cisco Nexus 93180YC-FX Switches using 4 x 10 Gbps break-out cables.

Cisco UCS Servers provide computing power within the VxBlock System 1000.

Each FI also has multiple ports reserved for FC ports. These ports connect to Cisco SAN switches and carry FC traffic between the compute layer and the storage layer. SAN port channels carrying FC traffic are configured between the FIs and upstream Cisco MDS switches. The Cisco UCS 6332-16UP Fabric Interconnects can be configured with 8, 12, or 16 FC connections per FI.

FEX within the Cisco UCS 5108 Blade Server Chassis connect to FIs over converged networking.

In a Cisco UCS Gen 3 environment, two or four 40 GbE connections on each FEX connect northbound to the FIs, regardless of the number of blades in the chassis. Cisco UCS C-Series Servers can connect directly to ports on FIs. Optionally, a pair of Cisco Nexus 2348UPQ FEXs can be used for increased Cisco UCS C-Series server scalability. These connections carry IP and FC traffic.

By default, servers in the VxBlock System 1000 boot VMware vSphere ESXi from local mirrored SD cards. Booting from SAN is optional.
