40cm PCIe 4.0 Ultraport Slimline SAS Breakout Cable, SFF-8654 8i 74Pin Male to Dual SFF-8654 4i 38Pin Male Slim SAS Internal Storage Cable for Server RAID HBA Backplane

This 40-centimeter Ultraport Slimline SAS breakout cable adopts SFF-8654 Slim SAS architecture, converting one 8-lane SFF-8654 8i 74Pin port on RAID/HBA controllers or server motherboards into two separate 4-lane SFF-8654 4i 38Pin interfaces. It evenly divides PCIe 8 lanes into dual x4 channels to connect two Slim SAS backplanes or U.2 NVMe drive arrays simultaneously.

Fully compliant with PCIe Gen4 and SAS 4.0 industry standards, the cable maintains complete signal integrity without bandwidth loss at 40cm short length, delivering ultra-high throughput for database servers, AI computing hosts and 8K video editing workstations. Adopting multi-layer aluminum foil + woven mesh differential shielding, it effectively suppresses electromagnetic interference generated by CPU, GPU and power modules inside dense server chassis.

The ultra-slim low-profile Ultraport connector design saves valuable internal space and optimizes cooling airflow for space-limited 1U/2U rackmount equipment. Every terminal uses thick gold-plated contacts and integrated safety latches to prevent accidental disconnection caused by long-running equipment vibration.

Compatible with mainstream Broadcom MegaRAID, Dell H745, HPE and Lenovo Slim SAS RAID cards, as well as all SFF-8654 equipped storage backplanes. Ideal for server hardware replacement, multi-drive storage expansion, data center infrastructure upgrade and high-performance DIY NAS construction.
