2008-Boot From SAN-Pagefile?
Hello All:I have setup three Windows Server 2008Enterprise x64 boxes in a boot from SAN scenario. These will be running Exchange 2007 in a CCR deployment.I have setup each server toboot from SAN. I have created a 45gb LUN for boot and 45gb for LUN for the swap file. I understand that I will not be getting crash dumps with this scenario but wecan change the swap location in the eventuallity that we do need to do intenset-shooting.I was unable to find if the old axiom is still true in 2008:It is best to set the Initial Size and Maximum Size values the same, to avoid fragmentation of the pagefile as it grows. A minimum value of RAM * 1.5 is recommended.My question is do I follow the Windows 2000 guidlines for page file settings in the scenario described?I have read this article regarding Boot From SAN and Microsoft's recommendation on Bootfrom SAN scenarios. http://support.microsoft.com/kb/305547/en-usThanks in advance,Michael BarbereHardware info:

The rule of thumb for the pagefile is still true for32bit versions of Windows Server 2008.For 64bit versions of Windows, Microsoft has released the followingKnowledgeBase Article:889654 How to determine the appropriate page file size for 64-bit versions of Windows Server 2003 or Windows XPThe AppliesTo section clearly states Windows Server 2008, although the title does not.
