I agree completely with your position, Greg. For the record, and not to confuse things, 64-bit Exchange 2007 with a lot of memory is supposed to reduce the I/O load enough that it should be reasonable to share drives in a SAN between Exchange other applications. I'm eagerly awaiting test results on this topic. If this is true, it should make the SAN story a little better for Exchange. At the same time, Exchange 2007 and CCR largely eliminates perhaps the lone compelling reason for a SAN, which is shared storage for clusters.

IMHO, it's a waste of money for most shops. We've got our Exchange servers on a CX-700 array, on one 4 disk raid 10 for the logs and another 7 disk Raid 5 for the stores, with about 1800 mailboxes. It works great, but when you look at the costs of the disks, shelf costs, Fiber ports, Power Path license, etc, it really isn't worth it until you get to the higher number of mailboxes (EX 4000+) even then with 07 still probably not worth it. As each FC disk really need to be dedicated to exchange and with 15k 146gb FC drives still going for about 1295.00 each, you could easily do the same thing on a dedicated MSA 500\1000\1500 (Insert you favorite dedicated disk array here) for half the cost, and get the same or better performance. Really EMC disk arrays on a san are of a different mindset than an Exchange admin would prefer, imho you setup disk arrays on the san to maximize the available space across all the disks, and arrange then to still deliver pretty good performance. You don't really want to dedicate disks for any one application as Exchange 2k\2k3 would like, as it's just too expensive, and you end up wasting what the array is built for. Just my $.02 worth though. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ed Crowley [MVP] Sent: Wednesday, August 15, 2007 9:00 AM To: Exchange Discussions Subject: RE: EMC as data store for Exchange? 160 mailboxes?! Big whoop! Talk to me when your SAN engineer makes you put all the stores and logs for 3,500 mailboxes on a LUN that is based on one 7-drive RAID-5 array.

We're still at Ex2K on a W2K network. Around 160 mailboxes but with Ex Std we're limited to max of 16 gig. We've had logs and data stored on EMC CX500 for about 4 years now. We've never had a problem. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of sms adm Sent: Tuesday, August 14, 2007 4:49 PM To: Exchange Discussions Subject: Re: EMC as data store for Exchange? I have just inherited Exchange as a responsibility and we are planning (I am told) to use EMC as a data repository. Does anyone else have Exchange setup this way and what are your experiences.
