vSphere 6.5 FT Limitations

Hi Gurus,

VMware FT has limitations. Where number of FT vm's per host and maximum vCPU's aggreagated across host is limited.

Can these be adjusted? If so what's maximum that can be adjusted to?

das.maxftvmsperhost - The maximum number of fault tolerant VMs allowed on a host in the cluster. Both Primary VMs and Secondary VMs count toward this limit. The default value is 4.

das.maxftvcpusperhost - The maximum number of vCPUs aggregated across all fault tolerant VMs on a host. vCPUs from both Primary VMs and Secondary VMs count toward this limit. The default value is 8.

Thanks,

Rushdi
