Vszerda SFF-8644 SAS 3.0 cable 1m 12Gbps

This 1m SFF-8644 to SFF-8644 cable connects external Mini SAS HD ports at 12Gbps per channel. It serves administrators wiring RAID controllers, HBAs or JBOD enclosures in server racks. The male-to-male copper assembly supports full-duplex SAS 3.0 operation for simultaneous bidirectional traffic.

Build integration with SFF-8644 links

The passive twinax construction requires no external power and fits directly into standard SFF-8644 receptacles on compatible hardware. Gold-plated connectors and 100 Ohm impedance-controlled pairs maintain signal integrity in dense rack environments. Reinforced strain relief withstands vibration from continuous 24/7 operation.

Capacity headroom at 12Gbps per channel

Each of the eight differential pairs delivers 12Gbps, yielding 24Gbps aggregate throughput for high-speed storage arrays. The cable remains backward compatible with SAS 2.0 6Gbps devices for gradual upgrades. It reaches its limit at 12Gbps; architectures demanding 24Gbps per lane need active or optical alternatives.

Questions about this item

How far can I run this 12 Gbps SAS cable before signal loss becomes the limiting factor?

The passive copper assembly is specified at 1 metre (3.3 ft) and meets the SFF-8644 insertion-loss target of <-12 dB at 6 GHz, so 1 metre is the supported reach at 12 Gbps.

What heat or noise does the cable add when it carries 12 Gbps traffic continuously?

The passive twinax construction has no active components, so it generates no noise and negligible heat; the operating range is -40 °C to +85 °C.

Which ports must my existing hardware expose for this cable to plug in directly?

Both ends use male SFF-8644 Mini SAS HD connectors, so the host and the target each need an external SFF-8644 receptacle.
