Flat 80cm cable with a wide 74pin MCIO connector splitting into two 36pin MiniSASHD ends

SMUGDESK

SMUGDESK MCIO x8 to 2×MiniSASHD x4 80cm Cable

SKU CH-7EJ6-B0Q2P

Converts a single 74-pin MCIO x8 port into two 36-pin MiniSASHD x4 connections for NVMe, SAS and SATA drives at 80cm length

  • PCIe Gen4 bandwidth for NVMe U.2 SSDs and RAID arrays
  • MCIO x8 74pin breaks out to dual MiniSASHD x4 36pin ports
  • Mini CoolEdge IO design fits low-profile high-density server nodes
  • 80cm length enables clean internal routing in rackmount chassis
  • Low-loss shielding maintains signal integrity with minimal crosstalk

MCIO x8 breakout for dual MiniSASHD

The cable splits a single 74pin MCIO x8 connector into two 36pin MiniSASHD x4 ports. It connects a PCIe Gen4 host interface to NVMe U.2 SSDs, SAS or SATA drives in enterprise servers and storage arrays. Builders expanding highdensity backplanes or upgrading data centre hardware will use it to add drive lanes without extra controller cards.

Gen4 signal integrity over 80cm run

Shielded construction keeps crosstalk and electromagnetic interference low across the full length. The design maintains Gen4 bandwidth for sustained RAID rebuilds, database workloads and sequential NVMe transfers. Signal loss stays minimal when the cable is routed through crowded rackmount chassis alongside power cables and other highspeed links.

Lowprofile routing in tight server nodes

The 80cm length reaches from a motherboard MCIO port to front or midplane backplanes without excess slack. Stiff shielding resists sharp bends but fits lowprofile drive cages and dense 1U or 2U layouts. Installers must verify the host MCIO pinout matches SFFTA1016 and that each MiniSASHD receptacle is wired for x4 operation; mismatched pin assignments or x1only ports will prevent detection.

Questions about this item

Does the 80cm MCIO x8 to dual MiniSASHD x4 cable generate noticeable heat or power draw when running continuously in a server?

The cable is a passive copper assembly with no active components, so it adds no measurable heat or power consumption during all‑day operation.

What connectors must already be present on my hardware for this SFFTA1016 74pin to 2×SFF8643 36pin breakout to work?

You need a single MCIO x8 (SFFTA1016 74‑pin) port on the host side and two MiniSASHD x4 (SFF8643 36‑pin) ports on the target backplane or RAID controller.

Will this Gen4‑compliant MCIO cable work reliably with older PCIe Gen3 SAS or SATA drives in the same enclosure?

Yes, the cable carries the PCIe Gen4 signal but is fully backward compatible, so Gen3 SAS, SATA and NVMe drives operate at their native speeds without issues.
