Sun x4540, Thumper, as FC Target?

Hey, is anyone out there using a Sun x4540 (aka Thumper) as a fibre channel target on their SAN?

The COMSTAR project that’s part of OpenSolaris appears to be able to make a volume available over the SAN. I’m very interested in that, but I’d like to know what other people think about it, especially in terms of stability & performance[0], before I go trying anything.

If you have any thoughts could you leave me a comment?


[0] Yes, I know it’s SATA, but for what I want to do, and across 48 drives, it’ll probably be fine. Plus they come with a god-awful amount of RAM. Go caching go!

  1. It’s a very interesting piece of software, I’m in the middle of a POC for a customer using the latest SNV build on a X4500.
    We’re currently stressing the new CIFS stack and is pretty damn good, I just briefly tried the FC target feature of COMSTAR, it’s a bit rough on the edges but performance-wise is excellent.
    You should try to get one of those babies under a try&buy agreement (usually 60 days) and do some tests yourself, remember that only 4G qlogic cards are supported with the QLT driver.
