I'd be wary of purchasing HP HBAs without getting a firsthand report from someone that they're compatible. I've seen several HP controllers that use LSI chip sets but are crippled in that they won't present drives as JBOD. That said, I've used a few of the HBAs sourced from LSI resellers and they work wonderfully with ZFS.
