I have a HP DL380 G5 with 8x146GB single port SAS SSF disks (DG146ABAB4).

A couple of them have failed and I can't find any new single port disks anymore. They all seem to be dual port. I'm wondering if I can mix the two disk types? Are dual port backwards compatible?

Yes, the dual-port drives are fine for internal chassis use. In fact, that's pretty much all you'll find available now. HP also sends the dual-ported 6G drives as warranty replacements. They are entirely backwards-compatible.
