What is the purpose of resource shares?
to set guaranteed maximum resource usage
to set guaranteed minimum resource usage
to prioritize resources when total resources are scarce
to prevent starting virtual machines when resources are scarce
Shares Specify CPU shares for this resource pool with respect to the parent’s total CPU resources. Sibling resource pools share resources according to their relative share values bounded by the reservation and limit.
Select Low, Normal, or High specify share values respectively in a 1:2:4 ratio. Select Custom to give each virtual machine a specific number of shares, which expresses a proportional weight. This will prioritize resources when total resources are scarce, (A).
Reservation Specify a guaranteed CPU allocation for this resource pool. Limit Specify the upper limit for this resource pool’s CPU allocation, (B)
Reservations will prevent starting virtual machines when resources are scarce, (A).
There is no option to set a guaranteed minimum resource usage (C) resource requirements are dependant on the Virtual machine not the resource pool.
