You say that like you don't mind having PCI in a server whose job is
to perform massive query over large data sets.
I am in my 4th week at a new job. Trying to figure what I am working
with.
LOOL, ok, hehe, not exactly the time to have a "let's change everything"
fit ;)

Many servers do have more than one bus. You have to process that data
too so its not going to be as much of a limit as you are suggesting. It
may be possible to stream a compressed data file to th

The LSI controllers are top-notch, and always my first choice. They
have PCI-X and PCI-e versions.

The servers have mostly have 12 drives in RAID 10.
We are going to redo one machine to compare RAID 10 vs RAID 50.
Mostly to see if the perfomance is close, the space gain may be
usefull.

From what I see I will likely get as much improvement from new hardware as
from re-doing
Will it pay to go to a controller with higher memory for existing
machines? The one machine I am about to redo has PCI which seems to
somewhat limit our options.
Urgh.

Good luck with that, you'll need it.

No the only controllers I had at the time were the 2120 and the LSI on

used Linux software raid.

Joshua,

I have one in mine, but I never actually ran any speed test.
Do you have any benchmarks that I could run and compare?

Most likely you have a scsi onboard as well I am guessing.
Will check.
shouldn't bother with the 2120. My tests show it is a horrible
controller for random writes.
Thanks for the feedback..

Inheritted a number of servers and I am starting to look into the hardware.
So far what I know from a few of the servers
Redhat servers.
15K rpm disks, 12GB to 32GB of RAM.

The servers have mostly have 12 drives in RAID 10.
