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.
