Cisco UCS 4th and 5th generation FI components provide compute power in the 3-Tier Platform. The following table shows the Cisco Nexus and Cisco UCS components:
Component | Description |
Cisco UCS 5108 blade server chassis
| Cisco USCM manages the 6U blade server chassis that houses FIs, fabric extenders (FEX), and servers. |
Cisco UCS B-Series blade servers
| B200 M6 servers Cisco UCS VICs:
|
Cisco UCS C-Series rack servers
| C220/240 M6 Servers Cisco UCS M6 VICs:
|
4th-generation Cisco UCS 6454 FIs
| Contains 2, 4, or 6 x 100 Gbps uplinks Configured with 4, 8, or 16 FC connections per FI |
4th-generation Cisco UCS 64108 FIs | Contains 4, 6, or 8 x 100 Gbps uplinks Configured with 8 or 16 FC connections per FI |
4th-generation Cisco UCS 2408, 2204XP, or 2208XP FEX | The FEX connects the I/O fabric between the Cisco UCS 6454 FI and the Cisco UCS 5108 blade server chassis. The Cisco UCS 64108 FI supports only the Cisco UCS 2408 FEX. |
Each FI reserves multiple ports to connect Cisco SAN switches and carry FC traffic between the compute layer and the storage layer. SAN port channels carry FC traffic between the FIs and upstream Cisco MDS switches. The FEX within the blade server chassis connects to the FIs over converged networking. By default, servers in the 3-Tier Platform boot VMware vSphere ESXi from local M.2 cards. Booting from SAN is optional.
The Cisco UCS 2408 FEX has eight external 25 Gb ports and 32 internal 10 Gb ports. Each FEX connects northbound to the FIs, regardless of the number of blade servers in the blade server chassis. The Cisco UCS 2408 FEX works with the Cisco UCS 6454 or 64108 FI at 25 Gbps.
Cisco UCS C-Series rack servers connect directly to the following FIs:
Each 3-Tier Platform contains at least two Cisco UCS FIs to form a HA cluster. Each FI pair:
The Cisco UCS 4th-generation components are:
