Cisco UCS M6 servers combine compute, network, storage access, and virtualization resources into a single converged system. Cisco UCS integrates a low-latency, lossless 10 GbE or 25 GbE unified network fabric with x86-architecture servers.
Cisco UCS B-Series blade servers and Cisco UCS C-Series rack servers provide:
For VMware deployments, the 3-Tier Platform can scale from three to hundreds of Cisco UCS servers.
The following table shows the maximum number of Cisco UCS servers that the 3-Tier Platform supports:
Server model and type | Servers per domain | Servers per system | ||
4th generation Cisco UCS 6454 FI | 4th generation Cisco UCS 63108 FI | Cisco Nexus 9336C-FX2 switch | ||
Cisco UCS 6454 FI | Cisco UCS 63108 FI | |||
Cisco UCS B200 M6 | 88 | 160 | 616 | 1,120 |
Cisco UCS C220 M6 C240 M6 | 44 | 80 | 308 | 560 |
The following table shows the maximum number of Cisco UCS B-Series blade servers to deploy that are directly connected with Cisco UCS C-Series rack servers in the same domain:

The following table shows the CPUs and memory that the Tier-3 Platform supports:

Order CPUs from the factory or by requesting an additional server through the expansion services. All Cisco UCS servers are pre-configured with local M.2 cards for operating system booting. For issues and concerns related to CPUs that are ordered as part of a converged system, Dell Technologies liaises directly with Cisco support.
Cisco UCS B-Series blade servers and Cisco UCS C-Series rack servers contain at least one physical Cisco UCS virtual interface card (VIC) for server connectivity.
The VIC passes converged FC and IP network traffic through the Cisco UCS 5108 blade server chassis midplane to the FEX.
The Cisco UCS C-Series rack servers can connect directly to each FI.
