Deployment Guide 23

• 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

. (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.

• Identify the limited resource by application type:
