Cisco UCS third and fourth-generation servers unite compute, network, and storage access and virtualization resources into a single Converged System.
Cisco UCS integrates a low-latency, lossless 10/25/40/100 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 VxBlock 1000 can scale from three to hundreds of Cisco UCS servers.
The maximum number of servers depends on the following criteria:
Mixed server models are supported, but impact the maximum quantity of allowed servers.
The following table lists the maximum number of supported Cisco UCS servers by domain and by system:

CPUs are available in all supported Cisco UCS M4 and M5 servers. CPUs can be ordered from the factory or by ordering an additional server through the expansion services.
By default, all Cisco UCS servers are configured with local SD cards for operating system boot.
Dell EMC contacts Cisco support for issues and concerns with CPUs ordered as part of a Converged System.
