Fiber Channel HBA compatibility?

[Nathan Shaffer]

We're running 2 HP LTSP servers that connect to a master server for all files, login, etc in a K-8 environment.  Currently, we're utilizing Ubuntu 8.10 LTSP but have a test server up for 10.04 LTSP.  Does anyone know of compatibility issues / problems with drivers in each of these distros with the possibility of installing a PCI-X fiber channel HBA in the LTSP servers to connect to the master server?  Is there an HBA card that is more compatible with Ubuntu drivers than others?

Thanks in advance,
