SATA Bridge Board
The DSN-654 SAS to SATA bridge board is designed to enable single-ported SATA drives to connect seamlessly like native dual-ported SAS drives. The DSN-654 is required for each drive, for SATA deployments in a dual controller configuration or with SATA hard drives having capacities of 3TB or greater, as described in the diagram below. Also, these same rules will apply to SATA drives installed in any additional DSN-6020 expansion enclosures.
