Ensure that the VMs that are hosting the Smarts Managers are allocated an optimal amount of memory. For the final testing of the Smarts Managers, VMware configured the VMs with 48 gigabytes of memory, which is the total amount of physical memory on each ESX host that was used in the testing.
Additional memory, more than any other factor, benefits the Managers the most.
Reserve memory for a VM in accordance with the guidelines in the Smarts IP Manager Deployment Guide. The criterion is the size of the total topology that is to be managed by all of the IP Availability Managers in the VM. Note that allocating more memory than needed increases the VM overhead.
Here are some other memory-related recommendations and considerations:
-
Check that adequate memory is allocated to the VMs. See “Ensure adequate allocation of CPU and memory resources” on page 188 for details.
-
Check the memory performance for the VMs. See “Monitor CPU and memory performance” on page 188 for details.
