Hardware raid controller

I'm looking for a SATA hardware raid controller with linux (gentoo) support.
If you know something and have some suggestion please write it.

I'm thinking about SuperTrak EX8300, is it good controller with kernel support ?

Hi Shakul,

Could you please clarify exactly what you are looking for? A true hardware raid contoller provides a transparent itnerface to the operating system - drivers / support is not necessary and if this is the case then any will do. If you are looking for a hardware-assisted software raid card (something like promise, highpoint, etc), then you can find out if a aprticular card is supported by finding out which chipset it uses, checking to see if your kernel has support available for that chipset, and seeing if the software you want to use supports it (i.e. dmraid). I am a little fuzzy on dmraid since I havent used it in a while, maybe somebody else can chime in and give you some additional information on that.

Alternatively, you might want to consider using pure linux software raid which has very good performance and is not hardware dependant, unlike raid configurations provided by certain manufacturers implementations of raid (i.e. promise raid may nto work on non-promise cards, or even other models of promise cards). The other advantage would be that you would be able to grow your array past the number of drives that any one card could support (a software raid array could span 10 drives, all connected to different controllers, for example). mdadm is a software raid utility available on gentoo which is very easy to use.

Hope this helps,
RaceTM

I use a ITE Raid IDE controller and it works without any problem.
also promise controller will work

I've to create RAID 1 but without any interventions on OS. After create the mirror, operation system must see one disk. I just set appropriate parts in kernel to run the controller ant thats all.
