Supermicro - CBL-SAST-1270LP-100 SlimlineLP x8 (LE) na 2x MiniSAS HD x4 (STR), 70/60 cm

Engineered for high-density storage arrays, this Supermicro breakout cable delivers 12 Gbps per lane across eight lanes, splitting a single SlimSAS x8 connection into two MiniSAS HD x4 links. With asymmetric lengths of 70 cm and 60 cm, it accommodates staggered backplane placements while maintaining signal integrity.

Overview

The CBL-SAST-1270LP-100 is a SAS 3.0 internal breakout cable designed to connect a SlimSAS (SFF-8654) host controller to two MiniSAS HD (SFF-8643) backplanes or drive cages. Its low-profile left-exit connector on the SlimSAS end ensures a clean fit in space-constrained server chassis, while the straight MiniSAS HD connectors provide secure, vibration-resistant mating. Built with premium copper conductors and a durable PVC jacket, this cable supports both SAS and SATA drives, making it a versatile choice for mixed storage environments.
