	* CPU models in these families with slower physical core speeds are not supported due to undefined capacity/performance relative to Tested Reference Configurations. UC is sensitive to both the CPU speed and the CPU architecture. Most industry CPU benchmarks do not correlate well with UC application behavior, so "newer" or "faster" does not guarantee "better for UC".		* CPU models in these families with slower physical core speeds are not supported due to undefined capacity/performance relative to Tested Reference Configurations.

Max VM count per server with specs-based depends on the physical server configuration and the OVAs deployed. E.g. UCS C210 M2 TRC#1 deployed with multiple CUCM 7.5K user OVAs can support 4:1. If specs-based was used with a supported dual 6-core CPU and appropriate increases in memory and storage, the same server model running multiple CUCM 7.5K user OVAs could support 6:1.

-	Minimum physical core speed required is based on what UC virtual machines will be used, and at what intended load per VM. Processors of [[Unified Computing System Hardware\|Tested Reference Configurations]] are sized for full-load virtual machines. It is recommended to use processors with same or higher speeds, as Cisco UC does not test or document lower performance points.

	Recall that physical CPU cores may not be over-subscribed for UC VMs at this time (one physical CPU core = one vCPU core).		Recall that physical CPU cores may not be over-subscribed for UC VMs at this time (one physical CPU core = one vCPU core).
