LSI Dual Port SAS Adapter 2× SFF-8643 to 2× SFF-8644 12Gb/s network card

SKU CH-26Z1-89HNV

Connects internal SFF-8643 and external SFF-8644 SAS devices at up to 12 Gb/s with included full-height and low-profile brackets

  • 12Gb/s SAS transfer speed for fast data movement
  • Backwards compatible with 6Gbps SAS and SATA drives
  • Two internal SFF-8643 ports plus two external SFF-8644 ports
  • Includes full-height and low-profile brackets for flexible installation
  • Plug-and-play operation with no driver installation required

Internal and External SAS Connectivity

This dual-port SAS adapter bridges two internal SFF-8643 ports with two external SFF-8644 ports, enabling 12Gb/s data transfer between servers, JBOD enclosures and direct-attached storage. It targets system builders and IT administrators who need to extend SAS connectivity beyond the chassis without adding a full RAID controller.

12Gb/s Link Speed and Backwards Compatibility

The adapter operates at up to 12Gb/s per lane and remains backwards compatible with 6Gb/s SAS and SATA drives, so existing disk shelves can be reused. Cable length, signal integrity and the capabilities of the attached expander or backplane set the practical throughput ceiling in any given deployment.

Full-Height and Low-Profile Brackets Included

Both a full-height and a low-profile bracket ship with the card, allowing installation in standard rackmount servers or space-constrained 1U and 2U chassis. The plug-and-play design requires no driver installation, reducing deployment time during maintenance windows or capacity upgrades.

Questions about this item

Should I pick the version with two internal SFF-8643 and two external SFF-8644 ports?

That is the only version listed; it gives you two internal and two external Mini SAS connectors on one card.

What does the 12 Gb/s figure mean once the card is installed?

Each attached SAS or SATA drive can transfer data at up to 12 gigabits per second per lane.

Which interface standard does the card use and what does it limit?

It uses the SAS interface, so the 12 Gb/s per lane ceiling applies to every connected SAS or SATA device.
