LORDWORLD

LORDWORLD Internal Mini SAS SFF-8087 to SFF-8643 Cable 50cm

SKU CH-19N6-DHCNF

Connects a SAS/SATA adapter to a backplane using SFF-8087 and SFF-8643 interfaces at 50cm length

  • Connect SAS/SATA adapter to backplane with SFF-8087 to SFF-8643 cable
  • 50 cm length fits standard server chassis layouts
  • Meets SAS 2.1 6 Gb/s specification for reliable throughput
  • HD Mini-SAS connectors ready for SAS 3.0 12 Gb/s future upgrades
  • Internal copper construction maintains signal integrity in dense enclosures

Connectors and Standard

This cable links an internal Mini SAS SFF-8087 port to a Mini SAS High Density SFF-8643 port. It is built for server and storage chassis where a SAS or SATA adapter must connect to a backplane. The HD connector follows the SAS 2.1 specification and is forward-compatible with SAS 3.0.

6 Gb/s SAS 2.1 Compliance

The single specification that determines fit is the 6 Gb/s SAS 2.1 rating of the SFF-8643 connector. Controllers or backplanes that require the older SFF-8087 interface on one side and the newer high-density interface on the other will work; any device that demands a different pin-out or signalling rate will not.

Four-Lane Capacity and Length

Each end carries four lanes, giving enough bandwidth for typical RAID arrays and JBOD enclosures running at 6 Gb/s per lane. The 50 cm length suits standard 2U and 4U server layouts; longer runs or external bulkhead connections would need a different cable.

Questions about this item

What does the 12Gb/s rating mean for this SFF-8643 connector when installed in a current server?

The SFF-8643 connectors on this cable are designed for the SAS 3.0 specification and will support 12Gb/s speeds when paired with a compatible 12Gb/s controller and backplane, but the cable itself meets the SAS 2.1 standard at 6Gb/s today.

Which SAS standard does the SFF-8643 end conform to, and what throughput does that limit me to right now?

The SFF-8643 end follows the SAS 2.1 standard, capping the link at 6Gb/s per lane; the connector is forward-compatible with SAS 3.0 for future 12Gb/s use.

What clearance and connector orientation do I need to fit this 50cm cable between my RAID card and backplane?

The cable is 50cm long with straight SFF-8087 and SFF-8643 plugs; ensure your chassis provides enough depth for the 50cm run and that both ports accept standard Mini SAS x4 connectors.
