Dual-port SFF-8644 to SFF-8643 adapter

This adapter converts two external SFF-8644 Mini SAS HD ports to internal SFF-8643 connectors. It serves installers linking external 12 Gb/s SAS host ports to internal backplanes or controllers. The low-profile bracket fits compact chassis where a full-height bracket would not clear.

Supports 12 Gb/s SAS 3.0 data rate

The HD Mini-SAS SFF-8644 interface meets the SAS 2.1 specification and is defined for the 12 Gb/s SAS 3.0 standard. This single speed rating determines whether the link can sustain the throughput required by modern SAS SSDs or HDD arrays. If the attached subsystem negotiates a lower rate, the adapter will operate at that speed.

Low-profile and standard brackets included

Both mounting brackets ship with the card, letting the installer choose the bracket height that matches the chassis slot. The PCBA female connectors accept standard SFF-8643 cables on the internal side. No drivers or configuration software are required; the adapter is a passive mechanical and electrical pass-through.
