Supermicro CBL-SAST-1201F-100 - Cable

12 Gbps per lane across four lanes — the Supermicro CBL-SAST-1201F-100 delivers the bandwidth modern SAS 3.0 storage demands. This internal Mini-SAS HD cable links controllers, backplanes, and drives with a straight-through SFF-8643 connection on both ends, ensuring a clean, reliable signal path inside servers and storage arrays.

Overview

Built for dense server and storage environments, this 1-meter cable uses 30 AWG conductors and 100-ohm impedance to maintain signal integrity at SAS 3.0 speeds. The black jacket and shielded construction reduce crosstalk and EMI, while hot-plug support allows drives to be swapped without downtime. It is fully RoHS compliant and compatible with Supermicro HBAs, backplanes, and other SAS 3.0 devices.

What stands out

• Dual SFF-8643 connectors: secure, high-density Mini-SAS HD interface on both ends.
• 12 Gbps per lane: full SAS 3.0 throughput for demanding workloads.
• 100 cm length: ideal for internal routing between controller and backplane.
• Shielded, 30 AWG construction: minimizes interference and preserves signal quality.
• Hot-plug ready: supports drive replacement without system shutdown.
