Shares – Select the virtual machine's relative priority for sharing the server platform memory. The values are Low, Normal, High and Custom. The more shares a virtual machine has, the more often it gets a time slice of a memory when there is no memory 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.
