Added more memory...Does swap have to be changed?

[savoy6]

I went from 32 to 64 GB of memory on several of my ESX 3 servers. Do I also need to change the size of my swap, or am I OK? Is there a process to change this?

Thanks,

Miguel

The swap partition is only used from the COS.

VMs use their own dedicated swap (vswp file residing (per default) in the same location were the vmx file is located)

If you don't change the memory allocation for the COS you don't have to change the swap size.

What is your swap size now?

Isn't there a max swap size of 8Gb or something like that.....hmmmm maybe it is 4Gb I forget.

2GB on i386 according to the howtos

I remember what it is. The max memory you can assign to the service console is 800Mb so the max you would need to make the swap is 1.6Gb...double the ram the service console can use. The vm's use a separate swap file that is stored with the virtual machines files. So for practical scenarios just make your swap 1.6Gb and if you ever need to you can grow your service console memory to 800Mb without a problem.

So unless you need to grow your service console memory you shouldn't need to grow your swap. The vm's if needed use swap files that are stored with their files.
