Enterprise fanout cable for SlimSAS 8X hosts
This professional cable converts a single SFF8654 74pin SlimSAS 8X port into two independent SFF8643 36pin MiniSAS HD 4X connections. It serves as a direct replacement for Broadcom MPN 056000300 and is fully compatible with Broadcom RAID controllers and server hardware. The design targets enterprise servers, storage backplanes and highdensity enclosures that require reliable highspeed SAS and NVMe connectivity.
Passive shielded assembly for stable signal
The servergrade shielded construction minimises signal loss across the 80cm length, preserving ultrahighspeed transmission without active components or external power. As a passive copper cable it adds no heat or audible noise to the chassis, leaving thermal and acoustic profiles entirely dependent on the host system. Power draw is negligible and limited to the signalling lines provided by the controller.
Dense internal routing with secure latch connectors
The 80cm optimised length supports flexible routing inside rackmount servers and storage arrays while the SFF8643 MiniSAS HD latching connectors resist vibration induced disconnects. Each fanout leg terminates in a standard 36pin interface compatible with common backplanes and drive cages, simplifying cable management in crowded chassis. Buyers who need a singleport SlimSAS cable or a different lane split will require an alternative part.

Questions about this item
How do I connect the SFF8654 74pin SlimSAS 8X host port to the two SFF8643 36pin MiniSAS HD 4X ports using this cable?
Align the 74pin connector with the host port keying and press firmly until the latch clicks; then seat each 36pin connector into its backplane or drive cage port, verifying both latches engage.
What replacement interval should I plan for this fanout cable in a continuously running server?
The cable has no moving parts or consumable elements; replace only if physical damage, connector wear, or signal errors appear during diagnostics.
What is the first limitation that appears when the cable runs at full SAS or NVMe throughput for extended periods?
Signal integrity over the 80cm shielded run is the limiting factor; the design targets low loss so the link remains stable at rated speeds.
