Windows Server 64-bit recommended page file size
I picked this up a while back when I was doing research for my RDS cluster.
Recommended page file sizes:
- Windows Server 2008 R2:
Minimum page file size: 1x RAM
Maximum page file size: 3 x RAM or 4 GB, whichever is larger
- Windows Server 2012 and R2:
Minimum page file size: Depends on crash dump setting*
Maximum page file size: 3 x RAM or 4 GB, whichever is larger More Info: Technet
I found this from a forum on the internet:
For WS 2008/R2, C drive 66 GB irrespective of OS version and platform. C drive should have 6GB page file.
Aforementioned are basic requirements.
As best practice, you need to set page file 1.5 Times the RAM available on any Windows Servers.
Say, you have 16 GB RAM on a server, 1.5 times the RAM 16 GB = 24 GB; you need to set 24 GB Page file on the Server.
Now, how would you ditribute the page file ?
Here is the way, You need create a separate Drive and split the Page file (other than the preset page file on C drive)
For WS 2008/2, C drive already has 6 GB, now on a newly created drive set 18 GB page file (i.e. 24 -6=18 GB), make sure you have at least 23 – 25 GB Drive to accomodate 18GB page file.
I use the above settings on my RDS servers.
