Hardware RAID cards typically have relatively huge chips with heatsinks, This isn't a very good description. There are non RAID HBAs that have large heatsinks as well. ASIC package (chip) size is irrelevant. This is a result of the lithography feature size (65nm/40nm/32nm) not the complexity of the logic. battery-backed onboard ram, and cost $300+ new. Real hardware RAID HBAs do have DRAM on board, anywhere from 128MB to 2GB. Most RAID cards ship without the battery module. It's optional. And your price point is high. Adaptec's entry RAID cards are very reasonable. Newegg has 5 models from $199-245. All have 128MB DRAM and support RAID1/10/1E but not 5/6. So I'd say $200+ is more accurate. Most that support parity arrays are typically $300+. Go ahead and use software raid instead. If you're sticking with that Sil3114 card then yes, use Linux md/RAID (mdadm). Performance, compatibility, troubleshooting, etc will all be better than fakeRAID. -- Stan -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

If it were hardware raid, then when you install Debian it will only see one disk (the hardware RAID being transparent to Debian).

Looking for a Branded server with HW Raid support in Debian
Hi I plan on using Debian Server in my office but to prevent downtime, I wanted to use a Branded server like IBM, Dell or HP with RAID-1 mirroring hotswap drives. Has anyone had experience with them and could make a recommendation on which model to buy? I had bought an IBM server last year with a Hardware RAID controller and implemented RAID-5. Although Debian installed fine, the RAID tools were made by IBM only for RedHat, Suse, Turbo Linux and Windows. I tried converting the rpm to deb, but wasn't able to get it to work. :-( Regards Rishi -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]
HW raid 0 setup
I'm trying to setup a Raid0 using a SCSI LSI Raid controller card and four 9G SCSI drives. The intent is to have two drives (sda and sdb), both of which use Raid0. During POST I can get into the controller bios and set it up for Raid0. I then continue on with the normal boot process, which yields the dmesg attached at the bottom of this email. I'm trying to make sure I've got this set up correctly and I'm concerned about the following 2 dmesg statements: SCSI device sda: 35094528 512-byte hdwr sectors (17968 MB) SCSI device sdb: 35094528 512-byte hdwr sectors (17968 MB) Is this correct? Since I'm setting this up as Raid0, shouldn't sda and sdb be half that size at 8984MB each? Or is it typical of Raid0 to report the combined size of the two drives it uses for striping? Also, my lsmod shows ... raid0 3104 0 (unused) md 43840 0 [raid0] megaraid 24896 3 (autoclean) Since raid0 is going unused, I take it that I don't need it.
