They are 'winraid' / 'fake raid' as it is BIOS supported software RAID. If you want real hardware RAID have a look at 3Ware's products. > Does CentOS4 add anything to this as it is based on 2.6 kernel? Kernel 2.6 too supports 3Ware controllers well. > My question upon reading what I found on Google, is if it is true > hardware raid, shouldn't the OS not be able to tell it's raid at all? Right, the system sees 1 drive rather than the independent drives. Thats the difference between hardware RAID and software RAID. > I'm assuming that the chipsets listed above are driver based hardware > raid? what I am after is a raid array based on true hardware raid such > that the OS see's just one drive, and the hardware firmware handles any > mirror/striping. Correct :) > Any suggestions? Yes, 3Ware - from small controllers to those with RAID5 capability and several SATA connectors. ICP Vortex may be a good choice too. The stories about Adaptec controllers do not invite to be interested in them. > Franki Alexander -- Alexander Dalloz | Enger, Germany | GPG http://pgp.mit.edu 0xB366A773 legal statement: http://www.uni-x.org/legal.html Fedora Core 2 GNU/Linux on Athlon with kernel 2.6.11-1.14_FC2smp Serendipity 19:22:18 up 3 days, 16:02, load average: 0.22, 0.31, 0.32 -------------- next part -------------- A non-text attachment was scrubbed...
