Sorry if this has been asked previously. Does CentOS support IDE hardware RAID on HP DL320? Thanks, -j
I've got several of these beasts (DL320 G2) and I haven't been able to
get
hardware RAID to work. The output of 'lspci' reports:
00:02.0 RAID bus controller: Silicon Image, Inc. SiI 0649 Ultra ATA/100 PCI to ATA Host Controller (rev 02)
I believe this chipset is dependent on a Windows-based driver to make it work and is NOT supported in CentOS. I'm using software RAID 1 on them and am fairly happy with it.
The standard answer for "fake raid" cards from "Linux SATA RAID FAQ" http://linux.yyz.us/sata/faq-sata-raid.html
3. I have a Silicon Image SATA RAID card. Why doesn't Linux support my hardware RAID? A. It's not hardware RAID. It is software RAID, provided by the BIOS on the card.
Indeed. I freaked out when I couldn't get my sata promise raid controlling working in Acer Altos series servers... Till I read an article that said in 2.4 its actually just as quick (if not quicker, depending on server hardware) to let the kernel deal with the raid stuff.
