I've seen some concerns about buying database performance hardware
from DELL. Are there at least some of the RAID cards that work well
with Linux or should I stay clear of DELL permanently?
Thanks!

Hi list,
We have a database with lots of small simultaneous writes and reads
(millions every day) and are looking at buying a good hardware for this.
What are your suggestions. What we are currently looking at is.
Dual Quad Core Intel
8 - 12 GB RAM
10 disks total.
4 x 146 GB SAS disk in

More RAM would be helpful. It's not that expensive, compared to the rest
of your system.

True, as long as
If you have a good RAID controller with BBU cache, then there's no point
splitting the discs into two sets. You're only creating an opportunity to
under-utilise the system. I'd get ten identical discs and put them in a
single array, probably RAID 10.
OK, thats good to know. Really want to

Would you turn off fsync if you had a controller with BBU? =)
No, certainly not. Fsync is what makes the data move from the volatile OS
cache to the non-volatile disc system. It'll just be a lot quicker on a
controller with a BBU cache, because it won't

The transaction logs are not that big, and there's very little value to
striping them across even two disks. You should just get more SAS
