The operating system is based on CentOS 4.4, but is modified, and runs a proprietary file system. It has pretty good performance and I'm happy with it.

They are emulex HBAs, and I guess there used to software called lputil, but this is no longer available at the Emulex site. It has been replaced by something called HBAnywhere, but I have not succeeded in building that on CentOS 4. Uprading the OS is out of the question I would think while maintaining the file system capability.

Have you tried to locate ex employees of that Company? Maybe you could 
hire some developer from that Company to help you out?
