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.  Either…

Why so much fluff?

When you use the Exchange 2007 Mailbox Storage Calculator on the face of it you seem to get a lot of fluff added to your storage design.  ..fluff upon fluff. Will run through some of the reasoning where it may not seem obvious in the cell comments themselves. LUN Free Space Percentage: couple of reasons…

Blackberry without BES?

Blackberries are great but BES (Blackberry Enterprise Server) can be an Exchange administrators nightmare..   One example being the significant load that BES can place on an Exchange Server.  As an example, a Blackberry device synchronising via BES version 4 would place two to four times the equivalent load of an Outlook user on your mailbox…

Getting your Exchange 2007 project approved – Part 3 (Storage)

Dynamic Disk Provisioning…

Have been tracking a few internal discussions concerning dynamic disk provisioning – the idea of being able to add disk capacity to the storage supporting your Exchange infrastructure at any time.  Now the way I understand it; and I imagine vendors and hardware platforms will do this in many different ways, is that larger LUNs…

E2K7 on NAS storage..?

The support policy for Exchange 2003 running on a NAS (Network-Attached Storage) device is pretty clear – we don’t support it.  A NAS device relies on file-sharing protocols such as SMB to attach to databases and logs and doesn’t scale very well for I\O.  The story doesn’t change with Exchange 2007 partly because, I presume,…
