Subject: Re: Single P4, many IDE PCI cards == trouble??

Message-ID: <200308311146.03877.jbriggs@briggsmedia.com> (raw)
In-Reply-To: <200308311443.55543.hpj@urpla.net>
I am successful in using the Tyan 2460/2466 motherboard with a 3ware 8-channel
IDE controller and 8 WD1200 drivers, and a single WD800 IDE system drive, and
4 bt878 frame grabbers.
However, on a Gigabyte GA7VXP via 400 with Athlon 2400 MP with onboard Promise
20276 controller with 2 WD1200's and a WD800 for the system drive and 4
framegrabbers, I get IDE DMA timeouts which are a symptom for future file
system corruption. I am using the /dev/ataraid device, and have not tried
this configuration using Promise's driver which creates a /dev/sda1 SCSI
device out of it. I have tried 3ware's 7000 controller with the
kernel-included (GPL) /dev/sda driver, and it results in lower probability of
file system corruption.
