LORDWORLD SFF-8644 to SFF-8643 PCBA Adapter Low Profile Bracket

SKU CH-SEJP-6DZXP

Connects external SFF-8644 and internal SFF-8643 SAS ports at up to 12Gb/s with a low-profile bracket

  • Supports 12Gb/s data transfer for high-speed SAS connectivity
  • Dual-port design connects external SFF-8644 targets to internal SFF-8643 hosts
  • Low-profile and standard brackets included for flexible chassis fit
  • Built to SAS 2.1 HD Mini-SAS specification for reliable 12Gb/s performance
  • Forward-compatible connectors align with upcoming SAS 3.0 generation

Dual-port SAS adapter for low-profile builds

This LORDWORLD adapter connects external SFF-8644 Mini SAS HD cables to internal SFF-8643 host ports on a printed circuit board. It targets system integrators and storage administrators who need a compact bridge between 12Gb/s external enclosures and internal RAID or HBA controllers. The low-profile bracket fits space-constrained chassis where a full-height bracket cannot be installed.

PCBA construction with choice of bracket heights

The bare board design keeps the assembly short while gold-plated contacts maintain signal integrity at 12Gb/s. Both a low-profile bracket and a standard-profile bracket are supplied so the same card can be secured in either slim or full-height expansion slots. Dual ports allow two independent external links without occupying additional slots.

12Gb/s transfer rate per the SAS 2.1 specification

The connector pair is rated for 12Gb/s operation under the SAS 2.1 standard and is forward-compatible with the SAS 3.0 specification when deployed. Buyers who need a single-port adapter or a cable-based solution rather than a board-mounted bracket will need a different product.
