Microsoft Exchange 2010 Standard Hard Drive configuration

I have a very simple question that many posts skirt or deflect a concrete answer.

I am preparing to purchase a server to install Exchange 2010 as a backend server.  I am trying to figure out the proper drive configuration.
I am sure I need separate OS drives, Log File Drives, and DB drives.
Do I need anything else?
My plan was to put the OS and Log Files both on seperate RAID 1 pairs and the DB on RAID 5.
Do I need additional drives?  Should the DB be on a RAID 5 or a RAID 1?

your config will also be good honestly for 220 users it wouldn't matter much


I would recommend a minimum of 4 cores  (8 betters) and 16 gb ram min don't worry about the rest

If you can afford it space wise raid 1 for the db is much better than raid5. Raid10 would be even better

So just the 3 sets/logical drives then?

I picked up a techrepublic blog that had the following:


C:  Windows and Exchange system files
D:  PAGEFILE.SYS
E:  MTA and SMTP queues
F:  Log files for the first storage group
G:  Databases for the first storage group


It seemed like a bit overkill as this would take a min of 8 drives using all RAID 1 and 10 using RAID 10 for the DB.

the best config will always be overkill

There is no advantage in having just logical drives but if you can have 2 disks (RAID1 for the OS and Pagefile and SMTP queues) 2 disks (RAID1 for the log files) 2 disks (raid 1) for the DBs

you will be just fine

I mistyped.  I mean virtual RAID drives.

So you would keep the Page File on the OS drive??  I was thinking if I had 3 drive sets of putting paging on the log file drive.

c:\ OS & MTA/SMTP queues
d:\ log files & pagefile
e:\ DBs

Thoughts?

Also, looking for a decent "don't break the bank" server for this.  Looking at the Dell PE R515 or maybe a DL360 with 8 drive bays.  Recommendations or other solutions that would work well for less $$?
