Hello all, request for comments; Those of you with experience using raid
controllers under linux, how much luck have you had and what hardware
configuration did you use? I'm trying to locate a reliable wide scsi-3
capable controller, but scsi-2 would probably be ok as well if it works.
Here's what I've worked with:
standard scsi
DPT 2024,
works real good, no problems with tape or cd IO using the EATA DMA
drivers.
NCR 53c810
works good, not to fast but no problems.
AdvSys (sorry, it's at home, don't remember the model)
works good, not to fast but no problems.
All these controllers were used with CD rom and tape drives as well as
SCSI hard disks. The disks ranged from a full height 320 meg seagate
(scsi-1) to a brand new seagate barracuda 4 gigger.
scsi raid
MYLEX
no linux drivers (damn!), so it's on a NT machine
Incredibly fast system, running a 18 gig raid 0 of two 9 gig wide
scsi-3 seagate barracudas. Takes about 22 seconds to format with
sector test the entire raid.
DPT 2044 with the 4040 raid module.
No luck, with the latest EATA DMA drivers as provided by the author,
this subsystem would suffer multiple scsi timeout problems even after
a firmware upgrade from DPT to address the problem. All
configurations we tried, enabling and disabling various options, and
changing cache etc. resulted in the same problem. The system
consisted of a single 2044 w/ 4040 raid module, and three 4 gig
Seagate Hawk drives in any raid configuration possible. We did not
try any other drives in any simular configuration as our time was
limited. (and my boss insisted there was nothing wrong with seagate
hawk drives).
