CBL-SAST-1249LP-85 Supermicro 61cm Cable

High-Density Internal Storage Breakout Cable enabling 8-Lane SlimSAS fan-out with the CBL-SAST-1249LP-85

The CBL-SAST-1249LP-85 is an internal SlimSAS host-to-backplane/expander interconnect designed to map an 8-lane SlimSAS x8 port to dual SlimSAS x4 endpoints with controlled lane integrity for enterprise SAS/SATA storage domains. In modern server platforms where CPU and PCIe Gen4/Gen5 expansion often converge on high-port-count HBAs or RAID controllers, this cable provides the physical layer needed to efficiently route lanes to dense 2.5-inch backplanes and NVMe-ready chassis wiring without introducing unnecessary connector height or bend constraints.

By using an aggregated x8-to-2x x4 topology, the CBL-SAST-1249LP-85 supports clean separation of storage paths for backplane segments or expander inputs while maintaining predictable serviceability. The low-profile straight connector orientation is optimized for tight airflow channels and short internal runs, reducing mechanical stress in 1U/2U layouts. With a 0.61 m overall length and matched individual legs, the CBL-SAST-1249LP-85 helps sustain consistent routing inside storage-heavy systems where cable management directly impacts maintenance time and signal stability.

Why Choose the CBL-SAST-1249LP-85?

The CBL-SAST-1249LP-85 delivers a practical density-to-performance connection model for servers that must scale drive counts while keeping internal topology simple and auditable. It enables reliable lane fan-out from a single controller port, supports structured backplane segmentation, and fits low-clearance chassis designs where standard harnesses can obstruct airflow or complicate field replacement.

Supermicro designs interconnect components with a focus on platform-level compatibility, repeatable integration, and dependable operation in 24/7 data centre environments. This engineering approach aligns with modern rack standards by prioritizing service access, consistent connector fit, and predictable behavior across qualified server and storage configurations.

Key Applications:

• SAS/SATA backplane breakout connectivity
• Dense 2.5-inch storage server integration
• HBA/RAID controller internal lane fan-out
• Service replacement for qualified Supermicro chassis
