CBL-SAST-1219LP-85 Supermicro 19cm Cable

Low-Profile SlimSAS Internal Interconnect Breakout FFC for Dense Backplane Cabling with the CBL-SAST-1219LP-85

The CBL-SAST-1219LP-85 is a Supermicro internal interconnect cable assembly engineered to route an 8-lane SlimSAS host connection to dual 4-lane targets with minimal height and bend radius impact inside 1U and 2U chassis. By using a low-profile flexible flat cable (FFC) design, CBL-SAST-1219LP-85 supports clean cable management around CPU heatsinks, GPU risers, and high-density fan walls where airflow integrity and service clearance are critical.

In modern PCIe-based storage architectures, the CBL-SAST-1219LP-85 enables efficient aggregation and distribution of SAS/SATA or NVMe lanes from a SlimSAS x8 port on a host adapter, RAID/HBA, or backplane expander to 2x SlimSAS x4 backplane connectors. This breakout topology aligns with platforms that balance PCIe lane budgets, storage backplane zoning, and front-access drive density, while the 19 cm length is optimized for short-run internal routing to reduce slack, minimize obstruction, and maintain predictable signal paths within compact server layouts.

Why Choose the CBL-SAST-1219LP-85?

The CBL-SAST-1219LP-85 delivers a practical density-to-serviceability advantage for enterprise nodes by combining an x8-to-dual-x4 breakout with a low-profile RE/LE form factor that simplifies routing in space-constrained builds. Selecting CBL-SAST-1219LP-85 supports scalable backplane designs, consistent internal topology across clustered deployments, and reliable interconnect planning for storage-heavy configurations.

Supermicro designs internal cabling to match data center operational requirements, emphasizing repeatable mechanical fit, platform-aligned connector choices, and integration consistency across server generations. The CBL-SAST-1219LP-85 follows this engineering approach to support predictable assembly, maintenance workflows, and compatibility with modern high-density chassis standards.

Key Applications:

• SAS/SATA backplane interconnects in 1U/2U servers
• NVMe lane breakout to dual SlimSAS x4 backplanes
• Internal cabling for storage HBA/RAID to backplane
• Space-constrained low-profile cable routing
