Hi all, I’m a bit confused about number of vCPU that should be assigned to FSVM. For example, I have 4 nodes and each node with 2 sockets (i.e. 2 vCPU) and each with 16 cores (i.e. total 32 cores per node). When creating FSVM, for example, each FSVM needs 8 vCPUs, but I have 2 vCPUs per node only. And we need at least 3 FSVM, that means we need 24 vCPUs. Is that mean I must have at least 12 nodes? And each vCPU with 1 core only?
For Nutanix Files it depends on the connections and workload your Nutanix Files is used for:

Thanks everyone for the advise!
for database related or mission cretical vms i do 1:1 or 1:2 for other work load i do 1:4 or 1:6
32, But that means you do a 1:1 mapping. I always count with 1:6 for generic server workloads.
Thanks for all the information. Seems I misunderstood the word “equivalent”. I thought it means “number of CPU socket = number of vCPU”. Clearly it’s incorrect.
So in my example, how many vCPU are there per node if oversubscription is not used?
there is something call oversubscription , as jeroen mention dont confus yourself with physical core vs vCPU.
in your case dont woory about physical core just go ahead create FSVM with 8 core.
AHV lets you configure vCPUs (equivalent to CPU sockets) and cores per vCPU (equivalent to CPU cores) for each VM. Nutanix recommends first increasing the number of vCPUs when a VM needs more than 1 CPU, rather than increasing the cores per vCPU. For example, if a guest VM requires 4 CPU, Nutanix recommends using 4 vCPU with one core per vCPU.
