CBL-SAST-1229-100 Supermicro 14cm Cable

High-Density Server Storage Interconnect Harness optimised for 8-lane SAS/SATA backplanes with the CBL-SAST-1229-100

The CBL-SAST-1229-100 is an internal SlimSAS x8 to dual MiniSAS HD (SFF-8643) harness designed to map an 8-lane SAS/SATA controller interface into two backplane-facing endpoints with clean lane distribution and predictable signal routing. In modern CPU platforms where storage bandwidth is often constrained by PCIe-attached HBAs and RAID adapters, this topology helps maintain a direct, low-loss path between the controller and the drive backplane without unnecessary intermediate adapters.

By using a SlimSAS x8 host-side connector and two MiniSAS HD targets, CBL-SAST-1229-100 aligns with dense 1U/2U chassis designs that consolidate cabling near the PCIe expansion zone while preserving serviceability across backplane segments. The 14 cm straight-connector build supports tight bend-radius planning, reduces airflow obstruction, and improves cable management around memory channels, risers, and NVMe/SAS mixed storage zones. CBL-SAST-1229-100 is therefore best matched to storage-heavy servers requiring stable SAS/SATA lane integrity for RAID arrays, JBOD backplanes, and high-availability drive bays.

Why Choose the CBL-SAST-1229-100?

CBL-SAST-1229-100 provides an efficient density-to-performance interconnect for enterprises standardising on SlimSAS x8 controller ports while still deploying MiniSAS HD backplanes. The short internal harness reduces routing complexity, supports consistent assembly across fleet builds, and improves reliability by minimising connector transitions and unmanaged slack inside high-density chassis.

Supermicro designs internal interconnects with a focus on platform-level fit, mechanical tolerances, and repeatable integration into validated server and backplane ecosystems. This engineering approach supports enterprise deployment requirements such as maintainability, predictable compatibility, and alignment with contemporary rack-scale airflow and service-access standards.

Key Applications:

• SAS/SATA backplane connectivity in 1U/2U servers
• HBA and RAID controller cabling
• High-density drive bay expansion
• Mixed SAS/SATA storage arrays
