Available MemoryHi,
I have an Exchange 2007 server with 8GB RAM. We only have one server and it is a CAS,HUB and Transport server with less than 300 mailboxes. I noticed that my Available RAM is only about 7%. Do i need more RAM? Thanks TagaR Does Exchange Best Practice Analyzer provide any performance issues or
recommendations regarding memory usage? Are you experiencing any Exchange issues currently? Its not uncommon for Exchange to use all available memory and release it as needed for other programs. -- John Oliver, Jr MCSE, MCT, CCNA Exchange MVP 2009 Microsoft Certified Partner "Taga Rich" <newsgr***@microsoft.com> wrote in message news:RovZl.30839$Db2.14970@edtnps83...Show quoteHide quote > Hi, > > I have an Exchange 2007 server with 8GB RAM.

If you only have 7% free, that's 573MB of ram free. I would definitely add more ram. 8GB is the minimum recommended amount for a Server with all Roles, but sizing it with 300MB mailbox would put it up to around 10-12GB of ram. "Planning Memory Configurations" http://technet.microsoft.com/en-us/library/bb738124.aspx Oliver That's 300 mailboxes. Obviously not enough coffee and Redbulls this morning

But I would say that 8GB is probably the min I would run that configuration with.

Strange things happen when physical memory runs low. One of them is
system wide working set trimming, where each process dumps a quarter of the RAM allocated to it. It's like constantly being in cold start. I'd add more RAM. I'd also take a look at http://blogs.technet.com/mikelag/archive/2007/12/19/working-set-trimming.aspx "Taga Rich" <newsgr***@microsoft.com> wrote in message news:RovZl.30839$Db2.14970@edtnps83...Show quoteHide quote > Hi, > > I have an Exchange 2007 server with 8GB RAM.
