Hi all, I have a brand new CCR setup the mailboxrole servers have 7GB of memory and 10GB virtual page file. Right now after 3 days my Mailbox server is using 5GB of memory and 5GB of virtual, my question is is this a normal amount of memory and virtual memory being used? How often should I move the active node from a node to b node? When doing updates would you update the passive(i know with a CCR it's not exactly passive but you know what I mean) side first then the active? Thanks in advance.

Exchange is designed to use memory all memory you have available so this is normal. As you see its store.exe using the most of it. Its also deisgned to release RAM when another app request for RAM. Recommended page file size for mailbox role is RAM + 10 MB, but it can other numbers. There is no need to failover to another node under normal conditions unless you have a specific reason. The standard way of applying pathes is: Update the "passive node" first, reboot is needed and then failover, apply patch to the previous "active node" and reboot if needed

Thanks Lasse

The amount of RAM usage you are seeing is normal. E2K7 grabs as much physical memory as it can to improve performance. You can limit that for non-production or low usage servers, though. http://mostlyexchange.blogspot.com/2007/08/restricting-ram-usage-in-exchange-2007.html

Hi, I have 6GB in two Exchange 2007 servers on two different networks I support. On one server we were getting slowdowns due to Exchange showing 6.6GB committed memory and a 6.47GB swapfile. The database is 6.8GB. I restricted the memory to 4GB (64*8192=524288). Users started complaining of not being able to attach large files. I looked at the store.exe file and it was sitting on 98,000K which seems really low. I reset the msExchESEParamCacheSizeMaxvalue back to <not set> and now the memory only shows 225,000K. Help! I would just a soon have the memory maxed out. Is there a registry setting that needs to be changed? Thanks!
