I am getting a new Windows 2003 Enterprise Edition 64-bit server with quad Itaniums CPUs and 64 GB RAM. Very cool, but ... how to the old rules of sizing pagefiles apply in this new world.
The old rule-of-thumb for sizing pagefiles said it must be equal to or larger than 1 times the amount of memory, and preferably 2-3 times memory. Windows 2000 and other operating systems limit the size of a pagefile to 4000 MB per drive partition. So, on servers with 4 GB RAM we needed three drive partitions (C, D, and E) on which to create our pagefiles.
If these old rules are applied to my new situation (64 GB RAM) then I would need to partition my drive space into a minimum of 16 partitions, and maybe as many as 48 partitions. Hopefully, someone out there has insights on sizing pagefiles on 64-bit operating systems and/or sizing pagefiles on systems with very large amounts of memory.
I wonder what Microsoft recommends for systems with 512 GB RAM?
