Hitachi 9570 VS EMC Clarion CX400?
 

Have you thought about an LSI/StorageTek array?

LSI designed dedicated ASICs do all the RAID work in hardware rather
then
having a pentium system processor try to do the work with firmware.
The
pentiums in the LSI/StorageTek boxes are just handle controller config
and
traffic routing. With their BladeStore you can have lower cost ATA
with the
same management interface as the high performance D series.


Beware of BladeStore, looks like STK is having problems:

I would agree with the following:

Do not use IDE disk for databases, it is a good solution for static,
low perfomance data such as *.doc files, jpegs, email archieving etc.

More, smaller disks are better in a Database environment and I would
recommend 15K drives using Raid 10.

Unfortunately HDS and EMC do not publish real test of their equipment
but check out http://www.storageperformance.org/ for testing and ask
EMC and HDS why they don't test there arrays when LSI, IBM, SUN, Dell
and HP all openly test their arrays?

Give a choice I would probably pick the Clariion but not with that
configuration. But you will get similar performance from the
FastT600, Storagetek D240 or even the older D178 or FastT 700 for less
money.

Veritas will mask the issues that EMC and Hitachi have of growing
LUN's and Raid sets. Be careful when choosing your default block size
on your raid sets. Make sure they match your block size on your
database.

Good luck shopping.... Go with Qlogic or JNI as they perform better
in a Solaris environment.
