For what it is worth, we will have 7000+ mailboxes, at the old co. we used Netapps filers. New company (spinoff) and the mgmt. "dictated" EMC SAN. We're relying HEAVILY on EMC for the storage design with a good amount of input from our old co. Exchange guys who really know their stuff. The old company compared Netapps vs EMC before and decided to choose Netapps, but the spinoff is 1/4 the size of the old co. and decided upon EMC for Exchange and other online storage.
When you have utilized EMC SANs, did you design it or did EMC? Some details: 7000 user mailboxes 500 shared mailboxes 0.7 IOPS per mailbox 2 Exchange 2003 production back end servers (evenly split mailboxes) ~300 GB databases currently – expected to grow to ~600GB with this environment Thx in advance On 8/15/07, Ed Crowley [MVP] <[EMAIL PROTECTED]> wrote: > Without going into a lot of proprietary details, suffice it to say that most > of our customers are very large and therefore the SAN engineers are in a > completely different stovepipe than the messaging engineers.
