Vszerda Mini SAS HD Cable SFF-8644 to SFF-8643 2m

SKU CH-AAKW-E0WV3

Connects SFF-8644 to SFF-8643 at 12Gbps using 28AWG copper for servers and storage arrays

  • 12 Gbps single-channel bandwidth for high-speed server interconnects
  • 28 AWG oxygen-free copper wire reduces signal loss over 2 m length
  • 100 % open and short tested with 300 V dielectric withstand
  • Connects SFF-8644 to SFF-8643 interfaces on RAID cards and storage arrays
  • Insulation resistance of 10 M and conductive resistance of 2 for reliable electrical performance

12Gbps Server Interconnect Cable

This cable links SFF-8644 and SFF-8643 ports for server and storage arrays. It carries single-channel traffic at up to 12Gbps using 28AWG oxygen-free copper conductors. The two-metre length suits rack-to-rack or intra-chassis routing. Builders needing a different connector pairing or a longer run cannot use this assembly.

Sustained Signal Integrity

Each assembly passes 100 per cent open and short testing before shipment. The construction withstands a DC 300V 0.01s dielectric test and meets insulation resistance of 10M with conductive resistance of 2. These verified electrical properties keep error rates low during continuous high-bandwidth transfers rather than brief bursts.

Thermal and Power Profile

Passive copper construction draws no external power and adds no active cooling noise to the chassis. The 28AWG gauge limits voltage drop across the two-metre span without generating measurable heat under normal load. Installers requiring active equalisation or optical reach for higher-loss paths must select a different cable technology.

Highlights

  • 12 Gbps single-channel bandwidth for high-speed server interconnects

Questions about this item

Does the 28AWG copper wire generate noticeable heat during continuous 12Gbps data transfers?

The 28AWG oxygen-free copper wire is designed for low signal loss, and the cable is passive, so it does not generate significant heat during 12Gbps operation.

What controller or backplane ports are required to use the SFF-8644 and SFF-8643 connectors?

You need a device with an SFF-8644 port and another with an SFF-8643 port, such as a RAID card, HBA, or storage backplane supporting SAS connectivity.

Will this cable work with older 6Gbps SAS equipment using the same SFF-8643 and SFF-8644 connectors?

Yes, the cable is backward compatible with 6Gbps SAS devices using SFF-8644 and SFF-8643 interfaces, operating at the lower speed.
