Re: RH 7.2 and TX4

[John Burton <j.c.burton@xxxxxxxxxxxx>]

Supposedly 3Ware will start offerring their Escalade series of ATA RAID 
controllers again (4 & 8 channel). Also Promise SuperTrak SX6000 is 
*supposed* to work with Linux, but they only have binary modules for a 
handful of kernel versions.  Not sure how well I2O support will work 
with the SX6000. I couldn't get I2O to work reliably with the SuperTrak 
100 (worked okay on one machine, work okay once on another machine, then 
I could never get that machine to boot again with the SuperTrak 100 in 
it). Finally had to resort to 2 Promise Ultra100TX2 cards and 1 Ultra100 
card (3 Ultra 100 TX2 cards gave me results similar to what you were 
seeing - one card would drop to PIO mode and *slow* transfers). I would 
also get DMA and CRC errors on the slow card.  (Yes, I've already 
checked the drives, and all 6 100GB drives worked fine with the 
SuperTrak 100 when I had it working in the test machine and they work 
fine with the 2 Ultra100TX2 and 1 Ultra100 card combination) . Seems to 
be a BIOS limitation in the Ultra100tx2 (and Fastrak 100tx2 which is 
essentially the same card?). The Ultra100tx2 BIOS displays one screen 
for all 3 cards, but only detects 4 drives (6 were connected). When I 
had the Ultra 100 installed, it would display a seperate BIOS screen 
showing the two drives attached to it.

Hope this helps some...
