Database Maintenance in Exchange Server 2010

If there is one area of Exchange 2010 that was poorly documented and poorly understood it has to be database maintenance.  The problem stemmed from the significant changes that we made in the store for Exchange 2010 and a confusion of terms. This has led many people in the field to get confused about what…


Exchange Service Availability….For the greater good…

I recently authored a post over at the Exchange Team Blog about Exchange ESE and Windows Disk Timeout values. http://blogs.technet.com/b/exchange/archive/2011/11/17/windows-disk-timeouts-and-exchange-server-2010.aspx Whilst writing that article and especially researching how ESE timeouts have evolved, I began thinking about the history of Exchange availability and how the product has evolved over my time working with it… In the…


Is 3rd Party Message Archiving Necessary for Exchange Server 2010?

What’s the difference between performance and stress mode? Put simply, performance mode validates the storage performance against the standard parameters recommended…


Exchange 2010 - active and passive database IOPS

I have been involved with a few escalations recently (I don’t even work in support!), the cases have been mostly due to Jetstress tests failing – typically then the relationship between customer and storage vendor becomes more hostile and eventually someone points the finger at Jetstress or Exchange… this is often where I get involved…


Jetstress 2010 and Background Database Maintenance

Last week a colleague from the MCM Exchange 2010 community asked some questions about disabling Exchange Server 2010 Background Database Maintenance.  Essentially they wanted to know if they disabled  the checkbox for BDM, what would happen on the passive database copies? A response came back fairly quickly from Matt Gossage explaining that although the checkbox…


Strange Jetstress 2010 results..?

Are you running the latest version of Jetstress 2010 against data created using the beta ?  If so then you may see some very strange results because there are some minor updates from the beta version which mean that you cannot mix databases created using the beta version with tests run using the released version. …
