Most of the things in this email, from me are a personal opinoin, but I do spend a fair bit of time with these sort of things, these days.

I would'nt bother with a 3ware 8000 or a 3ware 9000 card these days, if you really do want to get 3ware, get atleast a 9650. And anything less than a 9550 should be considered only if you get a really good deal off ebay. And remember that battery backup unit. >> For me, in SATA RAID cards it's 3ware or nothing. Been using them for >> more than 8 years now. I used to think the same for a long time, till I started using Areca raid cards. Now, I rate 3ware well behind Areca on performance, reliability and ease of use. If you are doing raid-5 or raid-6 the performance difference is quite noticeable ( I've just recently switched my desktop from a 3ware 9650 to Areca 1220, and got a near 8% improvement in write performance, and 12% on read - raid5 5 spindles ). > So these cards are just plug n play?

Drivers for both 3ware and Areca are included in the CentOS-5.1 kernels. Btw, you might want to keep an eye on some of the not-that-expensive highpoint rocketraid, hey have some fairly decent stuff coming out these days. The issues with them however, the drivers have only recently gone into the mainline upstream kernel - and their userland tools are not quite there yet. But if you need something for 2 to 5 drivers, they are an option worth considering ( they do have drivers for centos-4 and centos-5 on their website ). -- Karanbir Singh : http://www.karan.org/ : 2522219 at icq
