[GRLUG] Rocks running on top of RHEL

Thanks for all the great information, the Linux clusters are coming out
of a major oil company that uses them for seismic modeling. They will
cycle clusters 2-3 times per year and use primarily HP or SGI gear
however the SuperMicro systems I have were part of a storage array and
were not of interest to my company so I was able to pick them up for
very little $$$.
I figured that the Supermicro motherboards would be supported but was
concerned about the 3Ware controllers. I checked the systems and you are
correct the 3Ware is only connected to 8 drive bays I do have x-tra
systems and could pirate another 3Ware card but am wondering if I would
be wasting my time. I guess I'll keep a couple to play with post the
rest on eBay and keep my eyes open for the next great deal.

A former Grid setup, huh. Did the company go belly up?

You are cool, The motherboard chipset is an Intel E7501 Chipset. Works
in Linux. Long time since it was added, 2.4.22 or so.
The 7506-8 3Ware controller is a go. They are the OLD 3Ware lines. Fully
supported since about 2.4.18 or maybe a bit earlier.
The Intel 82546EB Dual Port Gigabit Ethernet Controllers are Fully
supported by the e1000 module.

You will have to add another controller to the machine in order to get
more then 8 drives off the 3Ware controller. It only supports one drive
per channel. One thing you have to remember, GRUB will not boot on an
Array of larger than 2TB from the 3ware controller. IOW, put a new boot
drive in it rather than the 80GB WD.
Also, update all firmware/BIOS on the Motherboard and the 3Ware
controller *BEFORE* installing anything. The 3Ware controller will not
support drives larger than 120GB without the firmware update.

Ubuntu will work just fine on the puppies. But, you should install the
server variant of Ubuntu, with only CLI stuff.
