Flat black cable with a wide 72pin connector splitting into two U.2 plugs, 75cm long

SMUGDESK

SMUGDESK LSI 94xx SFF8643 72Pin to 2×SFF8639 68Pin 75CM SAS NVMe Cable

SKU CH-WE8N-2BNGF

Connects LSI 94xx RAID controllers to two U.2 NVMe SSDs via dual MiniSAS HD ports using shielded 75 cm cable

  • Optimised for LSI 94xx RAID controllers with direct Broadcom 55006500 / 55006400 compatibility
  • Dual-channel SFF8643 72pin to dual SFF8639 68pin drives two NVMe SSDs independently
  • 75cm shielded copper length enables clean internal routing in dense server chassis
  • Low-loss construction maintains stable high-bandwidth transmission for mission-critical NVMe RAID
  • Precision-shielded conductors minimise signal attenuation and crosstalk under heavy workloads

Dedicated LSI 94xx NVMe Cable

This dedicated interconnect cable is engineered exclusively for LSI 94xx series RAID controllers. It converts two SFF8643 72pin MiniSASHD 8X ports to dual SFF8639 U.2 NVMe interfaces for enterprise storage deployments.

Broadcom Part Compatibility

The cable serves as a direct replacement for Broadcom official part numbers 55006500 and 55006400. This ensures seamless hardware integration without requiring adapter modifications or firmware changes for supported controllers.

Controller and Drive Verification

Verify that your RAID adapter provides SFF8643 72pin MiniSASHD outputs before ordering. Confirm your target solidstate drives use the SFF8639 U.2 connector format. The 75centimeter length suits standard rackmount server chassis routing.

Questions about this item

Will the SFF8643 connectors or the SFF8639 ends need replacement first under heavy RAID workloads?

Both connector types are built with precision-shielded low-loss conductors designed for stable high-bandwidth transmission, so neither end is expected to wear out before the other in normal enterprise use.

What limits throughput when two NVMe SSDs run sustained writes through the 75cm dual-channel assembly?

The cable supports 8X MiniSASHD signaling on each SFF8643 port, so the practical ceiling is the RAID controller's lane allocation and the SSDs' own write endurance rather than the interconnect itself.

How much extra heat or power draw does the shielded copper cable add when installed in a rackmount server running all day?

The passive low-loss copper construction adds negligible heat and no active power draw; any temperature rise comes from the controller and SSDs, not from the 75cm cable itself.
