Exchange 2003 And High Average Disk Queue Length And Pages/Sec Val We have Exchange 2003 environment, in perfmon “Average Disk Queue Length” is showing too high >=99 and store.exe also consume memory to high in all of the servers. 1 All exchange folder/file is excluded from Antivirus scanning. 2. /3G already set on all servers. Dinesh

I would look at: http://technet.microsoft.com/en-us/library/aa997558(EXCHG.65).aspx Ruling Out Disk-Bound Problems and also run ExBpa against the server http://www.microsoft.com/downloads/details.aspx?FamilyID=dbab201f-4bee-4943-ac22-e2ddbd258df3&displaylang=en Exchange uses all the RAM it cant and releases it when it necessary, so that alone is not an indicator of a problem.

Hi Dinesh, Is you server connected with SAN ? For which disk you are seeing high queue length for Average Disk Queue Length. you need to check evenr/error at storage side too. http://pal.codeplex.com/ Anil
