there are many many raid controllers out there that aren't actually hardware raid. they may do some offloading but they still put some part of the RAID process on the cpu.

Hi All, first time post so please excuse any blunders

We are specifying two servers using supermicro X7DBE+ MB and want to add on a SAS controller for Raid 10. We want to use the CentOS 4.4 X86_64 distro.

We are currently considering an Intel CC SRCSAS144E SAS Raid Controller for the servers using 4 Fujitsu 147 GB SAS HDD, and a Adaptec SASC RAID 4805 8-port for the server using 6 Fujitsu 147 GB SAS HDD.

Any feedback on this distro, the supermicro X7DBE+, or SAS controllers would be appreciated.

Thanks

I have supermicro X7xxx boards and they work fine with Centos-4 x86_64 (you do need .4 since it includes a new enough e1000 driver).

Regarding the SAS controllers the only thing I run on Centos-4 is a few Dell rebranded LSI things. They seem to work ok (no extra drivers, uses megaraid_sas) but I can't say I've been pushing them hard.
