Mini SAS 12G cable with SFF-8644 connectors on both ends, 1.0m length

Qnap

Qnap CAB-SAS10M-8644 Mini SAS 12G adapter SFF-8644 1.0m

SKU CH-67YM-GGP96 MPN CAB-SAS10M-8644

Connects SAS storage enclosures with a 1.0 m SFF-8644 Mini-SAS cable for 12 Gbit/s links

  • 12 Gbps SAS bandwidth supports high-throughput storage arrays
  • SFF-8644 connectors on both ends link compatible QNAP enclosures directly
  • One metre length fits standard rack-to-rack or shelf-to-shelf deployments
  • Designed for REXP-1220U-RP, REXP-1620U-RP and SAS-12G2E expansion units
  • Mini-SAS form factor keeps cable routing tidy in dense chassis

Qnap 12G SAS adapter cable

The Qnap CAB-SAS10M-8644 is a Mini SAS 12G cable built for direct SFF-8644 connections between compatible storage enclosures and controllers. It suits administrators expanding Qnap REXP or TVS-ECX80U-SAS systems with a reliable 1.0m link.

Practical limit of the SAS 12G interface

This cable supports the 12G SAS standard over a 1.0 metre run using SFF-8644 male connectors on both ends. Signal integrity is maintained within the specified length; longer distances would require active optics or repeaters not covered by this passive assembly.

Replaces shorter Mini SAS links

It upgrades from .5 metre cables when rack spacing or cable routing demands the extra reach between a host adapter and a REXP-1220U-RP or REXP-1620U-RP enclosure. The jump is worth it only when the shorter variant cannot span the physical gap without tension.

Questions about this item

Should I choose the 0.5 m or 1.0 m Mini SAS cable for my rack?

Select the 1.0 m length when devices are in adjacent racks or need extra slack; the 0.5 m version suits same-shelf connections.

What does the 12 Gbps rating mean when the cable is installed?

Each of the four lanes runs at 12 Gbps, so the link supports the full SAS 12G speed your controller and drives negotiate.

How does the SFF-8644 interface limit performance in practice?

The SFF-8644 connectors are built for SAS 12G signalling, so they do not restrict the 12 Gbps per lane the compatible QNAP enclosures and controllers provide.
