Exchange related question on IOPS
Posted on 2011-02-15
We have a remote site running Exchange 2007 in SCC - Active/Active/Passive on Windows 2008 Server. The environment was sized for about 1500 users and we worked with vendors on SAN disk configuration etc.
We're now going to deploy BES there to keep them inline with company policy.
I understand there will be an increase in IOPS - roughly about 4 times the IOPS for each user we BES-enable.
We haven't gone into the details, so this question is more hypothetical really, but is the solution to increased IOPS more disks in the SAN array? What if the array has no more space for disks? Is there anything else I can do?
