Ask Slashdot: IDE Software RAID?
Edward Schlunder asks:
"After setting up
Software RAID on a SCSI system at work,
I want to do the same at home for fun.
Call me crazy, but I'm just completely
geeked up about this after seeing it working.
The Software RAID documentation says that
each hard disk should be on a separate IDE
cable and that RAID5 requires at least 3
hard drives. I want to use my two existing
IDE hard drives and get the large, fast,
and cheap IBM IDE ATA/66
Deskstar 22GXP hard drive to make up
the third..." There's one small problem
though. Hit the link for more.
"My motherboard only has two IDE ports. So, my question is, what IDE controller card can I get that satisfies the following:
- Supports Linux (obviously!)
- High speed, preferrably ATA/66 and PCI
- Lets you use multiple controllers in one system (that is, it can co-exist with the onboard IDE controller on my SuperMicro P6DBE motherboard)
Please refrain from suggesting that I should just use SCSI -- the goal here isn't absolute greatest speed and reliability, but a cheap way to teach myself more about RAID5 and provide a test system to blow things up on without causing users unnecessary grief ;-)"
As long as you have good IDE controllers (no huge bottlenecks), try FreeBSD's RAID/LVM system "Vinum." It would require trying an OS other than the media baby of today, but that's definitely worth it anyway.
If you _REALLY_ want to see great performance, try FreeBSD using Vinum and setting SoftUpdates on on the Vinum volume.
(Now just watch this be moderated down for being a troll, because I suggested something different...)
