Innocard Internal MINI SAS HD to External MINI SAS HD for Broadcom 95xx 96xx Series AIC

SKU CH-D2XM-DN4X1

Converts internal Mini SAS HD to external Mini SAS HD for Broadcom 95xx and 96xx PCIe 4.0 add-in cards

  • Changer TypePCIe Gen4
  • PCIe 4.0 support enables high-speed data transfer
  • Converts internal Mini SAS HD to external Mini SAS HD for Broadcom 95xx/96xx AICs
  • Dual-port SFF-8673 to SFF-8674 design connects internal and external storage
  • Built-in power management with 12 V to 3.3 V buck controllers and 6.5 A current limit
  • Compliant with SFF-9402 1.1 and SFF-TA-8613/8614 standards for reliable enterprise deployment

Internal-to-external SAS adapter

This adapter converts an internal SFF-8673 Mini SAS HD connector to an external SFF-8674 Mini SAS HD interface. It is designed for Broadcom 95xx and 96xx series add-in cards such as the MegaRAID 9670 and eHBA 9600 models. The board supports PCI Express 4.0 and NVM Express 1.4 specifications. It targets server and storage-rack deployments that need external drive connectivity.

Thermals and power characteristics

Dual onboard 12 V to 3.3 V buck controllers supply the re-driver with a programmable current limit of 6.5 A. A 3.3 V load switch protects the controller during power transitions. The design complies with SFF-TA-8613 revision 3.5 and SFF-TA-8614 revision 3.4 for signal integrity. No active cooling is required for normal operation in a server chassis.

Build quality and connector implications

Gold-plated 30 µ connectors on both SFF-8673 and SFF-8674 ports resist oxidation in dense rack environments. LED indicators show PERST# status with inverted logic for quick diagnostics. SMBus and CLKREQ# pathways pass through to the external connector for enclosure management. The PCB is manufactured in Taiwan and meets SFF-9402 revision 1.1 mechanical specs.

Questions about this item

How do I install the Innocard GD2808A AIC into a Broadcom 96xx series controller, and what step is often missed?

Insert the card into a PCIe 4.0 slot, connect the internal SFF-8673 1x2 4X and external SFF-8674 1x2 4X cables, then enable CLKREQ# and WAKE# in the system BIOS; skipping the BIOS enable step breaks link training.

What maintenance or replacement will the Innocard GD2808A AIC need during its service life?

The on-board 12V-to-3.3V buck controllers and 3.3 V load switch are rated for continuous operation; no scheduled replacement is required unless a power fault trips the 6.5 A current limit, in which case the full adapter must be swapped.

What limit appears first on the Innocard GD2808A AIC under sustained PCIe 4.0 x4 traffic?

The programmable 6.5 A current limit on the dual buck converters is the first hard ceiling; sustained loads beyond that trigger protection and drop the link.
