Re: Partition Question

I'm also setting up a SBS Server but with SAS 6 drives (1 hot Spare).

Is there any performance benfits in having the OS + Exchange & SQL Logs on
RAID 1 and Exchange/SQL/user Data on RAID 5? I came across something on the
web that recommended having any sequential data on RAID 1 and random
accessed data on RAID 5.

Hi all and thanks in advance for any help.

I recently had to wipe and reinstall SBS 2003 SP1 R2 Premium single
nic. I have a raid 5 config with 4 250G SATA drives with one of the
drives configured as a hot spare (yes I know now I should not have
SATA drives but it is on a long list of mistakes I made with the
purchase of this server)

I'm not yet a fan of SATA on a server, but as long as it supports hardware
RAID and the disks are sufficiently speedy, you should be OK.


I am planning a partition scheme that looks like this:

C drive 65g (SBS including exchange & SQL server 2005)

OK...

D Drive 100g (Exchange Data and Logs)

Note that if you enable it in the registry, each exchange store (private &
public) can grow up to 75GB - so make sure you have sensible mailbox
quotas in place, set as defaults on each store, so you can't get anywhere
*close* to hitting your disk space limitations. And remember that DIRT
takes up space too (deleted item retention)

E Programs (CRM {Dedicated SQL Server instance for CRM}Office and
Small Business Financials 9.0)

Why have the binaries on their own partition? I put (most) binaries on the
system volume.

F CRM Data 100 G
G CRM Logs 10 G

Why not on the same partition/together? You'll get no performance benefit
as this isn't a separate physical volume.


H Files 50 G

Files meaning, user's shared files? Other data shares? Clientapps?

Where's your Sharepoint data?

I Down Loads UP Dates Remaning space

Not sure what 'downloads and updates' refer to....



How does this sound for efficency performance and fault protection.

It's really organizational, more than anything else. The fault protection
is in the RAID itself.

Or am I making this too hard?

I usually keep things simple -


System volume (Windows/Exchange/all apps) - am using about 40G on average
nowadays (YMMV)
Exchange databases/logs on their own partition
SQL data on its own partition
Normal user data on its own partition, including clientapps (and I
generally put clientapps under my own custom "distrib" share
