About the Symantec Performance Value Unit for kernel-based virtual machines
To calculate the Symantec Performance Value Unit (SPVU) for the products that run on kernel-based virtual machines (KVM), you need to install InfoScale Operations Manager managed host version 5.0.
When the SPVU is calculated for the products that run on the virtual machine, the total number of cores on the server is compared with the total number of Virtual CPUs (vCPUs) that are allocated to the virtual machines that have the same guest operating system and the same product. The smaller number among these two is the total number of cores that need to be licensed (core-to-license) for the server. The SPVU is calculated by multiplying this number with the SPVU value per core.
For example, consider a virtual server that has 3 virtual machines and a total number of 8 cores. Two of the virtual machines use 6 vCPUs each and run Storage Foundation for Windows. The total number of vCPUs on the virtual machine is calculated by adding 6 to 6, which is 12. To calculate the core-to-license for the virtual server, 12 is compared with 8 (the number of physical cores on the server). Because 8 is the smaller number, the core to license for the products on this server is 8. To find the required SPVU for the products on this virtual machine, 8 is multiplied with the actual SPVU value per core.
When the SPVU is calculated for the products that run in the KVM cluster environment, the total number of vCPUs of all the virtual machines in the cluster is compared with the total number of cores on the server. The smaller number among these two is the total number of cores that need to be licensed (core-to-license) for the server. The SPVU is calculated by multiplying this number with the SPVU value per core.
For example in a KVM cluster environment, the total number of vCPUs on all the virtual machines in the cluster is 24 and the total number of cores is 35. To calculate the core-to-license, 24 is compared with 35. Because 24 is the smaller number, the core-to-license for the products on this server is 24. To find the required SPVU for the products in this cluster environment, 24 is multiplied with the actual SPVU value per core.
For the products that run on KVM, and are deployed on the server as well as the virtual machines, the total number of cores on the server is used to calculate the SPVU.
