Supermicro - CBL-SAST-1271F-100 Slimline x8 a 2x Slimline x4, 92/71cm

Modern servers and storage systems often face a shortage of Slimline SAS ports, making it difficult to connect multiple high-speed drives. The Supermicro CBL-SAST-1271F-100 solves this by splitting a single Slimline x8 (SFF-8654) host connection into two Slimline x4 (SFF-8654) device connections, enabling efficient use of available ports without sacrificing performance.

Who is it for

This cable is ideal for IT professionals, system integrators, and data center operators who need to connect multiple SAS or SATA drives to a single Slimline x8 connector on a motherboard or RAID controller. It is suitable for servers, workstations, storage arrays, and other high-density computing environments.

Main features

• Host connector: Slimline SAS x8 (SFF-8654 8i) with straight orientation
• Device connectors: 2x Slimline SAS x4 (SFF-8654 4i) with straight orientation
• Main cable length: 92 cm (36.2 inches); branch lengths: 92 cm and 71 cm (28 inches)
• Supports data transfer rates up to 24 Gbps per lane (SAS 4.0), backward compatible with SAS 3.0 (12 Gbps) and SATA III (6 Gbps)
• High-quality 30 AWG conductors with 100 Ohm impedance for reliable signal integrity
• Gold-plated contacts for corrosion resistance and optimal conductivity

Tips

When installing, ensure the host connector is firmly seated and the branch connectors are routed to avoid strain. The unequal branch lengths (92 cm and 71 cm) help reach drives in different positions within a chassis. For best performance, use with Supermicro motherboards or RAID controllers that support Slimline SAS x8 ports.
