Adjusting the VMware RAM memory (vSphere desktop client)

Last Updated : Dec 14, 2020 |
  1. Using the vSphere desktop client, select the Inventory view.
  2. Locate the required virtual machine in the inventory navigation tree on the left. If not shown, select ViewShow VMs in Inventory.
  3. Click on the virtual machine.
  4. Right-click on the virtual machine and select Edit Settings.
  5. Select Memory.
  6. Adjust the maximum memory size for the virtual machine. See IP Office Server Profiling.
  7. Click the Resources tab and select Memory. Allocate the RAM for the virtual machine. See IP Office Server Profiling.
    ADDITIONAL INFORMATION:
    • 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 – 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.
  8. Click OK.
Next steps
  • If doing as part of installing a new virtual machine, continue with any further profiling required. When completed, start the virtual machine (see Powering On a VMware virtual machine).
