Just a question for the other experts out there..
On a virtual server with a 10k SAS Array and a 7.2k SAS Array, where would you put the Exchange databases?
-It's an organisation of 20x SBS2011 users
-Space on the 10K array is limited to 300GB (we need to use it sparingly), 1TB on the 7.2k array
-All Exchange users will be using cached Exchange mode
-There are other LOB programs/databases which will be taking up a lot of the 10k Array, do we really need Exchange be on the faster array?
We normally put the OS and databases requiring fast access on the faster array and all data on the slower one including Exchange databases. Bearing in mind most of our clients are < 25 SBS users, are there any disadvantages to designing this way?
If the disks run a write cache, you will not notice much difference.
Make sure you have some form of RAID to cope with a drive failure. (mirror at minimum)
