Hello, all!
The post will share with you FusionSphere memory and CPU resource statistics method.
Physical host vCPU calculation formula: vCPU = socket * core * thread
Among them: socket is the number of slots on the motherboard, which is the "road" that the administrator said.
Core is the number of physical CPUs, generally called the number of CPU cores.
Thread is the number of hardware threads per core, ie the number of hyperthreads.
Formula 2: The virtual machine can use vCPU to calculate the formula vCPU_VM = ( vCPU - vCPU_iso) * cpu_allocation_ratio
Where: vCPU_VM: total number of vCPUs that the virtual machine can use
vCPU: total number of vCPU resources of the physical host
vCPU_ISO: number of vCPUs that the physical host has been isolated
Cpu_allocation_ratio: CPU reuse ratio set by the physical host;
That's all, thanks!
