Agreeing with everyone who has gone before. For ease of management of the
OS, RAID1 for the OS, RAID5 for the data, partitioned however your
experience tells you, and a hot spare.
An argument can be made for three sets of RAID1, as you get very easy
management and easy drive swaps. Remember that a RAID5 performs badly when
a drive fails, so the hot spare is a great help. You need to replace any
failed drive as soon as you possibly can, as the loss of the second drive
will mean the loss of the date on the set.
The downside of RAID1 is that one half of the drive space committed to the
array is lost. On the other hand, there is no sense to commit three drives
to achieve the same amount of useable space or a bigger volume that will go
largely unused.
UPS on the overall box, battery on the RAID card.

In my case, no - all storage is 'in the box', in all cases.
Given the size of your network and the data size you indicate, I'd
personally not look beyond a single box.

I agree, mostly.
But I do like a two drive mirrored set for the OS, and raid 5 for the
balance, with a global hotspare. I don't have it everywhere, but it's
great
peace of mind where I do :-).

IMO the MD1000 is drastically overkill. I'm running on a 2900 by itself
with 8 drives, and the only reason I upgraded from 6 drives was because
it
was the fastest way for me to deal with what turned out to have been a
bad
decision about partitioning.
Personally, I'd get the appropriate number of matching drives, plus a
hot
spare. I'd put the whole thing in a single RAID 5 array with 3
partitions - 30 GB OS, one for Exchange at about double the size you
think
you need, and the balance for data.
I have about 22 users and about 100 GB of data on my 2900, and my Dell
rep
ridiculed me for buying such a beefy server. I believe that over-buying
hardware has several advantages as long as you're within your budget -
more reliable, future proofing, etc. and I believe the 2900 is the
minimum
if you want redundant power. But that MD1000 really seems over the top
to
me. And my most compelling argument against getting it now - you can
add
it any time if you change your mind.

We are building a new 2003 SBS Server solution to replace our failing
SBS2000 box - see previous post today concerning RAID, etc
We have been speaking to Dell about a solution and have a
recommendation for a PowerEdge2900 with MD1000 attached. Here is the
config:
PE2900 - has RAID 1 ( using (2) 73GB 15K drives) - for OS only using
PERC 6/i controller.
M1000 - has a total of 7 drives (146GB 15K) - this will have (2) RAID
5s (3 drives each) with (1) Hot Spare.
1. Has anyone out there used the MD1000 with SBS2003 Premium?
2. If the about is acceptable, what partitioning would you recommend
for Exchange, SQL (not currently used in SBS2000, CAD data --need
great perforamnce for these files)?
We only house 45GB of data now and only grow 4GB per year. Have 5-10
users hitting DC, Exchange, files. Exchange 2000 is at 14GB after 6
years.
Otherwise we are considering just the 2900 III with similar config and
guidance from replies on our previous post today..

Have you implemented the Powervault storage attached to a Server
(Dell, or otherwise)?- Hide quoted text -

Thanks for the feedback. Versus your suggestion for RAID, what about
this total of 9 drives:
RAID1 (2x73GB drives) = for OS only = with 1 partition
RAID5 (3x146GB drives) = for Exchange, potential SQL, client apps =
with 2 partitions--1 for EXCH, 1 for SQL
RAID5 (3x146GB drives) = for Data = with 1 partition = for CAD files,
word docs OR 2 partitions 1 for each use???
1 HOT GLOBAL spare for both RAID5s
Does anyone see a performance issue or enhancement with this config?
Thanks!
