Exchange 2010 on a SAN

[Winnebago]

Does anyone out there have any experience with deploying Exchange 2010 in a
SAN? I'm curious how you sized and configured the LUNs. The capacity
planner does not do a good job of tailoring E2k10 in a SAN environment. It
likes DAS and JBOD. We're SAN and can't do it any other way.

Would like tips, suggestions, or articles if anyone has them.

Thank you!

As an employee of a "SAN Vendor" I have assisted in the same of over
half a million Exchange 2010 seats in this calendar year alone onto my
employer's storage.
Who is your SAN vendor? Ask them. If you were a NetApp house on the
eastern USA I would have given you chapter and verse on exactly how to
configure LUNs and what to take into consideration. All of my
counterparts at the other SAN vendors are fully versed in their own
solutions.
Sizing is barely any different. You know how much capacity you need
(logs, stores, snapshots) and you know how many IOPS you need to
provide to the server. That's micky mouse storage 101 stuff. The
carve-up of the disks is slightly more tricky and is dependent on the
vendor.
Unless you want to tell us what storage platform you have that's it
for the advice anyone can give you here. If you're a NTAP customer
then email me at marnold@ with your serial numbers and I'll either
answer your questions or arrange for someone in your Geo to.

Thank you for answering, Mark. I am so glad to know there are people out
there using SANs and not just JBOD. We don't have a choice. What we have is
what we have and we must move forward.

We are using a pair of HP6400s each with 60 disks. HP claims the IOPs are
around 2000 for that number of disks. This seems a little low but
conservative data is good for planning. Doing the math we can support 10k
clients using these arrays. We don't have everything in place yet to try
using Jetstress to get real numbers.

I only WISH I had NetApp! Done that before and it was fantastic!

Probably less than 2000. SATA disk is ~60 IOPS each so if you've
carved that up into RAID10 and taken a couple of hot spares out you're
at that number, ballpark.
