I just recently installed a PM3754U2 w/64meg in a Tyan MB with two Ppro
200s. I had to get the I2O drivers and build a custom kernel in order to
get it to work. Here's some of my experience...
0- According to DPT, some of the older PCI chipsets do not support I2O.
Therefore, depending on the age of your hardware, you may have some
difficulties. If your using older hardware and aren'ts sure, I would
consider trying to get one of the SmartRAID IV cards which was pre-I2O
I believe. Otherwise if your using anything recent, it should work OK. I
have a Tyan Tahoe II (I think) which is about 3 or 4 years old. So far it
works just fine.
1- The card has its own PCI bridge on the card. As such, it needs to be
installed in one of the busmaster slots, typically one of the first
three. I chose to install it in the first slot.
2- I had to get the source code for the I2O driver and build a new kernel
with it loaded. The machine I have is running 2.0.36-SMP. At first I
built the driver directly into the kernel. But, the card wasn't being
recognized during boot up (I boot off of IDE), so I made the driver a
module and then manually load the module during the boot process. The
card gets recognized and all is fine. I don't know if 2.2 kernel will
work better, but until I upgrade the system, at least it all works
reliably right now.
3- I installed 4 Seagate 18LP 9.1 gig 7200rpm drives, in a raid5
configuration. This gave me a 26+ gig "sda" drive visible to Linux. I
then partitioned the sda drive into 4 drives for use in various
applications. My root file system is on an IDE drive, and the raid5
system is used for Postgres database, home directories, and web hosted
directories. Database queries noticeably sped up on this. I don't have
any real benchmarks, but it is a screaming combination of drives and
controller.
DPT makes an excellent product in my opinion. I've used their cards in
various applications for over 5 years. This is the first time I have used
them in Linux though. I am quite happy with the card. I have since moved
the system from my workarea to a 'protected power' area. 21 days and
counting.
