CBL-0288L Supermicro 70cm Cable

High-Density Internal Storage Breakout Harness for SAS/SATA Backplanes with the CBL-0288L

The CBL-0288L is an internal MiniSAS-to-SATA breakout cable assembly engineered to map a 4-lane SFF-8087 host connection from a RAID controller or HBA to 4 individual SATA drive ports. In mixed SAS/SATA server designs, this topology supports clean lane distribution while keeping signal routing predictable for storage backplanes or direct-drive bays in enterprise chassis.

Designed for modern storage nodes where CPU platform and memory architecture determine overall I/O pressure, the CBL-0288L helps maintain consistent drive attach behavior under high queue-depth workloads. It integrates into PCIe-based storage architectures by enabling reliable connectivity from PCIe RAID/HBA adapters to SATA devices, and it supports SGPIO sideband for activity and status signaling aligned with backplane management. A right-angled connector geometry improves clearance in dense chassis layouts and reduces mechanical stress when cabling around fans, risers, and hot-swap cages.

Why Choose the CBL-0288L?

The CBL-0288L delivers a practical density-to-serviceability balance for 1U/2U platforms where internal space, airflow, and maintenance access directly affect uptime. By consolidating four SATA legs into a single MiniSAS host interface with sideband support, it simplifies storage expansion planning, preserves structured cabling for scalable deployments, and reduces integration risk during build-outs, refresh cycles, and field replacement.

Supermicro designs cable assemblies with an emphasis on data centre operability, including repeatable fitment within validated chassis ecosystems and signal integrity considerations appropriate for enterprise storage interconnects. The result is infrastructure-aligned cabling that supports consistent assembly practices, predictable service workflows, and compatibility with current server platform standards.

Key Applications:

• Internal SATA drive breakout from MiniSAS HBA/RAID ports
• SAS/SATA backplane cabling in 1U/2U storage servers
• Direct-attach SATA connectivity for dense chassis builds
• SGPIO-enabled drive activity and fault indication
