Blue SAS cable with SFF-8644 and SFF-8088 connectors, two metres long

Vszerda

Vszerda SFF-8644 to SFF-8088 SAS cable 2M 6.6ft

SKU CH-QA63-MFSJ4

Connects Mini-SAS HD SFF-8644 to SFF-8088 at up to 6 Gbps per channel over two metres

  • 6 Gbps per channel for fast data transfer
  • SAS 2.1 and 3.0 compatible for broad device support
  • Twinaxial 8-pair with 100 Ohm impedance ensures signal integrity
  • 2 m length suits rack-to-rack and DAS connections
  • Hot-pluggable design allows installation without system downtime

Connect SFF-8644 to SFF-8088

This two-metre cable links an SFF-8644 Mini SAS HD port to an SFF-8088 Mini SAS connector. It is built for servers, storage racks, RAID enclosures and direct-attached storage systems that need an external 6 Gbps SAS link. The twinaxial eight-pair construction supports SAS 2.1 and SAS 3.0 specifications for broad device compatibility. Hot-pluggable operation allows connection changes without powering down the chassis.

Verify port types and cable length

Confirm that one endpoint presents an SFF-8644 interface and the other an SFF-8088 interface before ordering. The fixed two-metre reach suits adjacent rack units or short external runs; longer distances will require a different cable. Ensure the host HBA or RAID controller and the target enclosure both operate at 6 Gbps per channel to match the cable rating. No driver installation is needed for the passive copper assembly.

Sustained 6 Gbps throughput with low skew

Each of the eight differential pairs maintains a controlled 100 ohm impedance and low skew, preserving signal integrity during continuous multi-drive workloads. The AWG30 twinaxial conductors and EMI-resistant shielding keep error rates low under prolonged RAID rebuilds or streaming backup jobs. The cable is tested to Serial Attached SCSI 6.0 Gbps certification before shipment, so sustained bandwidth matches the rated per-channel speed without thermal throttling.

Questions about this item

Does the box include anything besides the SFF-8644 to SFF-8088 cable itself?

The package contains one 2-metre SFF-8644 to SFF-8088 cable; no extra brackets, screws or adapters are supplied.

Should I choose this cable for a SAS 2.1 or SAS 3.0 host bus adapter?

It is fully compatible with both SAS 2.1 and SAS 3.0 interface specifications, so either generation works.

What does the 6 Gbps per channel rating mean when the cable is installed in a server?

Each of the eight twinaxial pairs carries up to 6 Gbps, giving full SAS 2.1 drive performance with low skew and 100 Ohm impedance.
