So I'm having a little difficulty parsing this: SAS 520 is actually a
financial audit standard (which I really wish I didn't know about) ... I
assume you're actually talking about DIF/DIX?  The integrity standard
for SCSI?

I've added linux-scsi, since this is a SCSI question not an IDE one. 

The only SAS HBA supporting DIF I know of with a working Linux driver is
the mpt2sas.  It supports DIF types 1 and 3.
