Apparently not.  SAS is SCSI the way SATA is IDE, I gather: the
protocol is more or less the same at the level of command and response
packets but the underlying transport is totally different and utterly
incompatible.

You cannot, for example, plug a SCSI disk into a SAS system, nor the
other way around, any more than a (P)ATA disk is of any use on a SATA
system.

Actually there are interface/protocol convertors to allow PATA drives on
SATA channels and vice versa
