If would not use the "raid" feature of the Highpoint cards, because it is only software raid and not so performant as a hardware raid. If you don't need a
please don't say things like this. HW raid is *NOT* generally
faster or better than software raid. yes, if you're building a quad-gigabit fileserver out of an old P5/100 you had sitting around,
you're not even going to start looking at sw raid.
One point. Hardware raid (and faux hardware raid) provides real hot swap with on-the-fly rebuilds.
Linux software raid can't (yet).
Both promise and highpoint proprietary ide raid drivers can, but no raw kernel or libata drivers can as yet, and the interface between the hotswap driver and md driver is no where near there.
With the Highpoint driver I get a drive failure and the card starts beeping. I fire up the management util, remove the faulty drive, swap it out and insert the new drive in the array. The array starts rebuilding - no effect on the uptime and only a slight loss in throughput. Plus it's seamless.
I used a pair of Highpoint Rocketraid 1540 cards with the Highpoint driver (as it presented all 8 drives as 8 units on a scsi chain) with linux md raid-5, and I have now moved onto 3 Promise SATA150-TX4 units in an md raid-5.
I did play with the highpoint raid-5 (which can now span controllers) and it's management features, hotswap and hot-rebuild were quite good.
Not that I'm advocating hardware or faux hardware raid, just noting that linux software raid still has a large deficiency.
