When using “Cluster resource percentage” for host failover capacity in vSphere HA Admission Control, the total
resource requirements are calculated from which two values? (Choose two.)
Total vCPUs assigned to each VM.
Average CPU usage on each VM over time.
Memory reservations on each VM.
Total memory assigned to each VM.
Average active memory on each VM over time.
CPU reservations on each VM.
vSphere HA uses the actual reservations of the virtual machines. If a virtual machine does not have
reservations, meaning that the reservation is 0, a default of 0MB memory and 32MHz CPU is applied.
Computing the Current Failover Capacity
The total resource requirements for the powered-on virtual machines is comprised of two components, CPU
and memory. vSphere HA calculates these values.
The CPU component by summing the CPU reservations of the powered-on virtual machines. If you have not
specified a CPU reservation for a virtual machine, it is assigned a default value of 32MHz (this value can be
changed using the das.vmcpuminmhz advanced option.)
The memory component by summing the memory reservation (plus memory overhead) of each powered-on
