Cluster Name	Total vCPUs	vCPU:pCore Ratio	Total Memory	Total Storage
Cluster1	257	4.0	1,195 GiB	18.7 TiB
Mgmt	80	4.0* (2.5)	233 GiB	1.7 TiB
DMZ	136	5.3	448 GiB	4.1 TiB

Notes¶

We assumed that the analyzed clusters were already configured with N+1 availability, so we accounted for one less host worth of cores when calculating the total number of physical cores. We used this equation:

(Number of Hosts - 1) * Average Total pCores per Host

The current DMZ cluster is comprised of processors that are several generations old, so the single thread performance difference was factored into the vCPU:pCore ratio:

(Total vCPUs)/((Number of Hosts - 1) * Average Total pCores per Host) * ((Projected Processor Single Thread Score = 1952)/(Current Processor Single Thread Score = 1402))

The Mgmt cluster calculated vCPU:pCore ratio is 2.5:1, a possible indication that the current infrastructure has very low CPU utilization. In this instance we’ve elected to use an assumed value of 4:1. Any assumed values should be clearly communicated to the customer and corrborated by additional historical data if available.
