SlimSAS SFF-8654 4i to U.2 SFF-8639 cable, 50 cm, black connectors

Vszerda

Vszerda SFF-8654 4i to SFF-8639 U.2 Cable 50cm

SKU CH-HXE4-0ZVKV

Connects a U.2 SFF-8639 device to a SlimSAS SFF-8654 4i controller at 24Gbps over 50cm

Cable Length 50 cm

  • 24 Gb/s SAS throughput for high-speed storage links
  • PCIe 4.0 8 GT/s per channel supports modern controllers
  • SlimSAS SFF-8654 4i to U.2 SFF-8639 connects drives directly
  • 50 cm length fits compact chassis routing
  • Shielded construction maintains signal integrity over full reach

Connection Overview

The Vszerda SFF-8654 4i to SFF-8639 U.2 Cable is a new 50cm interconnect built for PCIe 4.0 and SAS environments. It links a controller or backplane with a SlimSAS 4i port to a drive or enclosure using the SFF-8639 U.2 interface. The assembly supports 24Gb/s SAS and 8GT/s PCIe per channel.

Fit and Limits

This cable suits builders wiring U.2 devices to SlimSAS 4i connectors inside servers or workstations. It does not serve installations that require a different length, an alternative connector such as MCIO, or a direct SATA signal path without a compatible controller.

Deciding Spec

The 24Gb/s SAS and PCIe 4.0 rating per channel is the single figure that determines whether this cable matches the bandwidth needs of the attached storage device and host controller.

Questions about this item

How do I connect the SFF-8654 4i end to my controller and what is the common mistake?

Align the keyed SFF-8654 4i plug with the controller port and push straight in until it clicks; the frequent error is forcing it upside-down, which bends the delicate pins inside the SlimSAS connector.

What upkeep does the 50cm cable need over time?

No scheduled maintenance is required; simply inspect the SFF-8639 and SFF-8654 4i ends for dust or bent contacts whenever you reseat drives, and replace the cable if the latch tabs snap or the sheath shows kinks.

At what point does the 24Gbps SAS link hit its ceiling during heavy I/O?

The four-lane 24Gbps SAS interface saturates first; once aggregate throughput reaches that 24Gbps limit, latency climbs and queues build regardless of the 8GT/s PCIe 4.0 per-channel capability.
