Two one-metre SAS cables with SFF-8644 and SFF-8643 connectors

Vszerda

Vszerda SFF-8644 to SFF-8643 SAS 3.0 Cable 1m 2 Pack

SKU CH-H1TV-K6PHK

Connects SFF-8644 and SFF-8643 SAS 3.0 ports at up to 6Gbps in a two-pack of 1m cables

  • SAS 3.0 compliant for reliable server RAID links
  • 6 Gbps maximum throughput when hardware supports it
  • SFF-8644 to SFF-8643 connects modern and legacy gear
  • 1 metre length suits rack-to-rack cabling
  • Two cables included for redundant or dual-port setups

Cable purpose and fit

This two-pack provides external Mini SAS HD cables that connect an SFF-8644 port to an SFF-8643 port. They are built for administrators and integrators linking RAID controllers, JBOD enclosures or backplanes in server and storage racks.

Deciding specification

Each cable is compliant with SAS 3.0 and rated for up to 6 Gbps, so the link speed will match the slowest device on the chain. Verify that both ends of your connection use the specified Mini SAS HD connectors before ordering.

Thermals noise and power

Passive copper construction means no fans, no active cooling and no additional power draw. The 1 metre length keeps signal integrity intact for typical rack runs while adding negligible latency or heat to the installation.

Questions about this item

What does the 6 Gbps headline speed actually deliver inside a server?

The cable is compliant with SAS 3.0 and supports up to 6 Gbps per lane, but the real throughput depends on the controller, backplane and drives you connect.

Which SAS standard governs the SFF-8644 to SFF-8643 interface and what does it cap?

The connectors follow the SAS 3.0 specification, which defines a 6 Gbps signalling rate per lane for this cable assembly.

What physical clearance does the 1 metre, 2-pack cable need to fit in a rack?

Each cable is 1 metre (3.3 feet) long and uses standard SFF-8644 and SFF-8643 mini-SAS HD connectors that snap into compatible ports without extra brackets.
