Hi All

I am looking at installing a low cost raid card on a test machine. I want to see how well raid works and play with setting up etc on an Ubuntu 10.4 machine with a test Zimbra mail server.

I have read various reviews and want to make sure that this would work ok on Raid 1 with Ubuntu

Thanks

Glenn

Adaptec RAID 1430SA used 'hostraid', which is just fake raid.

It (probably) should work with ubuntu, but there is no offical support from adaptec.

It would be cheaper to just use motherboard SATA ports and setup software raid. Performance should be the same.

I would second this - IMO fake RAID is something to avoid. Either use a true hardware RAID or a software RAID from the Linux kernel. The smallest Adaptec controller is the RAID 2405 I fear which offers true hardware RAID.

With RAID 1 it’s also easy to boot from a mirrored pair of disk with software RAID, as the boot partition must be readable without the support of the kernel because it’s just going to be loaded. Later on it will be remounted as a mirrored device. If you would like to boot from a RAID 0 or a RAID 5 this won’t be possible with a software RAID though. You would need at least one partition which can be read at the early boot stage without support of the kernel.

This is where fake RAID offer some kind of “boot support” and switch then to a software RAID later on anyway.
