These were not a SAN, they were SCSI attached Arrays, some 45124 or
something like that, can't really remember. Replaced them simply
because they were getting old and we wanted to go to a SAN design. The
only issue we really had was that the power button on the back was not
protected, I was cable managing a rack and very easily hit one and
powered it down, made for a long day as it was an array that held a
couple hundred home directories.

Did you have any issues with Clarion?
What were they, if I may ask?
Thanks

We boot our IBM Blades, HS-20s and HS-40s from an IBM DS4500 and
IBM DS4800.
Some Pros:
1. Replacing a server is a snap, specially if you can use your
old HBA and don't have to change your WWN.
2. No need for a RAID controller for local drives.
3. Space, 14 Dual CPU servers in 7U of rack space
4. Power/KVM/Network cable managability
5. Can handle multiple drive failures and all systems stay
running
6. No waste, when my OS can run in under 7gig why RAID 1 a pair
of 36Gig drives.
Some Cons:
1. Swap File, we keep it locally, can't remember if that was our
determination or manufaturer's recommendation.
2. HBA is a single point of failure, but then so is your RAID
controller with local drives, never have had one fail.
3. Welllll, I'll think of something else later or someone else
will I'm sure.
We moved away from EMC's Clarion's several years ago, so I can't
comment on the performance of thier new stuff. We've seen very good
performance on the IBM FastTs.

EMC told me they support it but were trying to sway us away from
it.
We have an unmanaged datacenter, so they felt replacing a failed
server or HBA would add a layer of complexity for a level 1 tech to
achieve.
Also, they mentioned something about wasting LUN's for swap
files for the OS.
make any sense?
Thanks

Anyone have any pro or con for SAN booting win2k3 with
Exchange 2k3?
I know its supported by MS but I'm not sure if we should
go that route.
My manager is pushing for it.
We are about to purchase an EMC Clarion to put Exchange
2k3 on(which obviously i have no problem with) and SAN boot the
OS(unsure about that).
Thanks
