So far SAF-TE feature is only available in SCSI version of our mobile rack. You can use M35T with X5DAL-TG2, however, X5DAL-TG2 supports up to 4 SATA HDDs while M35T provides total 5 SATA HDD bays, so you will have 1 unused HDD bay in M35T. The alternative is to use our M34T which provides 4 SATA HDD bays.
