Supermicro - CBL-SAST-1225LP-85 Slimline x8 na 2x MiniSAS HD x4

For dense storage environments where a single SlimSAS x8 port must feed two independent MiniSAS HD x4 targets, the Supermicro CBL-SAST-1225LP-85 delivers a clean, low-profile breakout without signal compromise. Unlike generic adapters, this cable is engineered for Supermicro backplanes and RAID controllers, ensuring reliable 12Gbps SAS3 throughput across all eight lanes.

Highlights

• Breaks out one SlimSAS x8 (SFF-8654) host port into two MiniSAS HD x4 (SFF-8643) device ports
• Supports SAS3 12Gbps per lane for high-speed storage connectivity
• Low-profile, flexible 85cm cable ideal for internal rack server routing
• Gold-plated connectors and full shielding for signal integrity
• RoHS compliant, black jacket for clean builds

In daily use

Install this cable to connect a SlimSAS-enabled HBA or motherboard to two separate MiniSAS HD backplanes or drive cages. The 85cm length gives enough slack for tidy cable management in 1U and 2U chassis, while the low-profile connectors fit under low-clearance heatsinks. The dual breakout reduces cable clutter compared to using two separate SlimSAS-to-MiniSAS HD cables, and the robust construction withstands repeated plug cycles in serviceable systems.
