Reservation – This value sets the guaranteed minimum available RAM for the virtual machine. You cannot set the reservation higher than the maximum memory value. For IP Office virtual machines, the recommended value is 75-80% of the maximum.
Shares – The more shares a virtual machine has, the more often it gets a time slice of a CPU when there is no CPU idle time. Shares represent a relative priority for the allocation of memory capacity between virtual machines. For more information about share values, refer to the VMware Resource Management Guide.
Select Normal only if the IP Office virtual machine has exclusive use of the ESXi host. However, if other virtual machines utilizing the share mechanism present on the host, it is imperative that IP Office virtual machine is set to High. IP Office is a real-time telecommunication software that requires immediate access to hardware resources.
