I am going to run a large SQL Server with 60 users... Any thoughts on these
two servers?

One vendor is pitching the IBM x235 server... and the other is pitching the
HP Proliant ML570 G2...

The one vendor says that the IBM Dual XEON 3.2 Processors, 8 Gig of Kingston
RAM, and two 146.8 gig disks Raid 0 will do just fine...

But the other vendor says that the HP Dual XEON 2.7 GHz Processors, (4
processor capable server) with 2 meg cache, 8 gig of HP RAM, (2) 36 gig
drives for the OS Raid 0, and (5) 72.8 gig Raid 0+1 disks will blow the IBM
out of the water with performance.

The only difference I saw in redundancy is that the HP has a hot pluggable
redundant cooling fan.

Difference in price is only a few thousand... Is it worth it... and are the
statement(s) true?????

Your input is GREATLY appreciated.

Did you miss that the HP has RAID 0+1, meaning if a single drive dies you
don't lose all the data? I call that redundancy.

No didn't miss that...

Here is how it was explained to me:

The IBM was config'd for Raid 0 (mirrored drives) meaning if a single
drive dies you don't loose all the data...

The 0+1 in the HP means there are mirrored drives and 1 warm spare
as well as an on-line ready to pick up the mirror if one drive dies...
sort of a back-up to the back-up...

How I really should have stated it was...

The IBM and the HP both offer redundancy...
(power supply disk drive raid dual network path etc...)
However, the HP allows for a redundant cooling fan but the IBM does not.

RAID0 is not mirrored drives. RAID0 is striping. Two drives that look
like one drive of 2x the size to the OS. No redundency. Lose one drive,
lose all the data.

RAID1 is Mirroring, as in, two disks with identical information. Lose
one, the other still works.

RAID 0+1 is striping (two drives) + mirroring (an entire second two drive
set). One stripe mirrors the other stripe. If one drive fails, that
stripe is toast, but the other stripe (since it is mirrored) is still
good. Depending on what hardware and software, you could technically
lose opposite drives on opposite stripes and still be OK.

The IBM drive offers ZERO/!/ redundency on your disk drives. If the
salesmen is telling you different, either he doesn't understand the
difference between RAID 0 and RAID 1 (and is using the wrong term), or he
is flat out lying to you to make the sale. Either way, don't listen to
him.
