The IBM 59Y1902 is a 3-meter external SAS QSFP passive copper cable designed for high-speed storage interconnects in enterprise environments. With 28 AWG copper conductors and QDR (Quad Data Rate) capability, this cable supports bandwidth-intensive data transfers between SAS-attached storage arrays, servers, and external enclosures. The QSFP connectors on both ends provide reliable, hot-swappable connectivity typical of modern enterprise storage topologies. Compatible with IBM System Storage solutions and third-party SAS infrastructure that implements QSFP standards, this cable is commonly used in data center storage area networks (SANs), backup appliances, and high-performance computing environments requiring external SAS connectivity.The passive design—requiring no active signal conditioning—reduces power consumption and failure points while maintaining signal integrity across the 3-meter span. Ideal for connecting modular storage arrays to host systems or daisy-chaining multiple external enclosures.Tested and guaranteed; available via quote.
