IIRC - should do, yes - as you're always executing I/O tasks in parallel in
a RAID0 array. Just having 2 independent disks doesn't necessarily mean that
you'd be doing that.

This brings up another question. Does RAID 0 so better performance than
just a stand alone HD configuration?

The IBM HS20 and HP BL35p (SAS) seems to be lacking in the Raid Controller
cache arena as well... Enough so, that one customer is considering
abandoning RAID 1 in favor of a RAID 0 configuration... Initial benchmarks
are showing a HUGE improvement in Read, Writes, and overall performance.
But of course, you loose that redundancy.

Just heard back from our outside sales from Dell and was told that one
customer did a major test with Citrix and the Dell 1855 Blades and found
that Citrix ran 30% slower due to no enough cache on the Raid Controller in
their blades. Anyway the outside sales guy is recommending us to go with
the 1850 1u servers instead which basically defects the purpose of going to
blades (ex: density, wiring, power, etc......). Never thought I would
actually hear a sales rep recommend against their own product.
Anyway, just thought I would pass this along.

I appreciate all the information from everyone. From all the research that
we've done we are hoping to go with IBM Servers and Blades but if the
pricing isn't close we will most likely choose Dell. We understand IBM is
going to have better management, denisty, etc and if money wasn't a factor
IBM would be our #1 choice. But on the flip side with Dell, we are a Dell
shop, the Dell pricing is better, and Dell's support has been great.
I will say I'm very disappointed that no one brought up Hitachi's Blade
Servers or even Silicon Blade Servers. :-)
Thanks again for all the information and laughs!

I would like to know if anyone on this board has had any good or bad
experience with the Dell PowerEdge 1855 Blade Servers. We are currently
taking a hard look at using the Dell Blades for our Citrix Servers.
Thanks in advance!
