Hi,
We are getting a new server to replace our SBS2000 box . We currently
have (7) 36.9GB SCSI 15K HDDs that are setup as RAID 0/5 (=2 RAID
striped sets, (3)Drives each, with Hot spare) and partitioned the
system as follows:
C:\ OS = 12GB
D:\ EXCH 2000 = 8GB
E:\ APPS = 40GB (exchange database, clientapps, user folders)
F:\ DATA = 80GB (Solidworks CAD file, misc files)
Goals:
- 1 Server
-SBS2003 Premium
-Better performance accessing Solidworks CAD files. (plan on 15K
drives)
-We do not need SQL Server but would like the option to use it, so we
plan to include it in install
-Exchange Server 2003 (2007 preferred)
-We currently have a total of 45GB, including the 14GB Exchange
database, to store and grow about 4GB/year in data
- ISA server is in default configuration --ie we do not configure
anything special.
- Use Symantec Antivirus/Client security.
We are looking at Dell PE2900 III configured with Tape backup for less
than $10K.
What would be:
1. Proper RAID/Partition structure for SBS2003?
--Confused on configuring different RAIDs versus best performance for
each use (eg. RAID1 for OS versus RAID 0/5 or 5 for DATA, Exchange
2. Size HDDs to purchase.
For your size outfit, you're not really going to see any performance
gain in using multiple arrays vs a single array with more disks.
A small array (3 disks) does not perform as well as a large array with 7
disks in many instances.
Make one large R5 array with a hot spare.
Make one large partition "C" on the drive, all space.
Setup your folders and organize data off the root, so that you're not
putting files in the root of the C drive.
Create something like the following:
C:\COMPANYFILES
C:\COMPANYFILES\PROFILES
C:\COMPANYFILES\REDIRMYDOCT
C:\COMPANYFILES\HOMES
C:\COMPANYFILES\SHARES
C:\COMPANYFILES\SHARES\COMMON
C:\COMPANYFILES\SHARES\PROJECTS
C:\COMPANYFILES\SHARES\ACCOUNTING
C:\COMPANYFILES\SHARES\HUMANRESOURCES
C:\COMPANYFILES\SHARES\UTILITIES
...
You get the idea.
As your company grows you won't have to worry about running out of space
on a partition.
Use JKDefrag weekly top fully optimize the array space and leave slack
space.
If you were actually going to hammer this server with SQL and Exchange,
well, you would want Exchange on ARRAY 2, SQL DATA on ARRAY 3, SQL
Transaction logs on ARRAY 4, and your OS on ARRAY 1 with user data on
ARRAY 5 - a typical 12 drive system for real performance.

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!
.
