Capping the Resources on VM
I am starting to put different capping policies on VM resources such as CPU, Memory, Storage and Network this week.
The concept is very simple, but implementation takes a lot more thinking and planning than the followings:
High: 2000 vCPU, 20 VM RAM
Normal: 1000 vCPU, 10 VM RAM
Low: 500 vCPU, 5 VM RAM
High:Normal:Low = 4:2:1
For example, a VM with 1 vCPU and 1GB (1024MB) RAM Shares = NORMAL
So CPU Shares will show 1000 and Memory Shares wil show 10240.
In fact, after the capping starts to kick in, I begin to fall in love with VMware’s Resources Managment!
