Supermicro SAS Cable SFF8643-SFF8643, 80 cm, Blue

Supermicro SAS Cable SFF8643-SFF8643 – 80 cm Internal Data Link

This Supermicro SAS cable connects two SFF-8643 internal ports, enabling high-speed data transfer between SAS devices within a server or storage enclosure.

• 80 cm cable length provides flexible routing inside server chassis without excess slack
• SFF-8643 connectors on both ends ensure a secure, high-density connection for SAS backplane or HBA interfaces
• 30 AWG construction supports 12 Gb/s SAS-2 speeds with minimal signal loss
• Blue jacket allows quick visual identification in dense cable management environments

What sets this cable apart

The SFF-8643 form factor is the standard internal SAS connector for Supermicro servers and storage nodes. This cable bridges two identical ports on the same device or between a host bus adapter and a backplane, maintaining signal integrity at 12 Gb/s over its 80 cm length.

Ideal for

IT administrators and system integrators building or maintaining Supermicro-based servers and JBOD storage enclosures that require reliable internal SAS connectivity.

Application of Supermicro SAS Cable SFF8643-SFF8643
