Dell 2.12 manual Identify the limited resource by application type

•Tradeoffs between memory and CPU resources:

•If VMs are CPU-bound and RAM is under-utilized, then turn off page sharing. You can achieve this from the ESX Server Management User Interface (MUI):

•Choose Options tab.

•Next, click on Advanced Settings.

•Set Mem.ShareScanTotal to 0. (The default is 200.)

•If VM peak memory is bursty, then decrease idle memory tax rate. From ESX MUI:

•Choose Options tab.

•Next, click on Advanced Settings.

•Set Mem.IdleTax to the rate of your choice. (The default is 75%.)

•VMware performance metrics can be accessed by exploring the directory structure at /proc/vmware within the Service Console.

•For better backup practices, it is recommended to create two virtual disks for each virtual machine: one virtual disk containing OS/application installation files and the other virtual disk containing user data. This allows for more frequent backup of the data virtual disk.
