Yeah; I cheated and just used the theoretical maximum slow/narrow PCI throughput. I'd really like to be able to report a "this value makes no sense" figure, since there's no good way to compute a "base transfer speed" for an array. > > Apart from that: the ciss driver is fairly new AFAIK, I didn't find a lot > > of references to it on the web.

It's in production at Yahoo!, although still a bit green. There's documentation available from Compaq that would let you write a basic monitoring tool (I can help here), but no chance of Compaq's own tools being released anytime soon. If you were really masochistic, you could probably get all of Compaq's monitoring goo for your machine running under Linux emulation, but I suspect it'd be a job of work.
