Fervit Slimline SAS 4.0 SFF8654 8i 74Pin to 8 SATA 7Pin 50cm Fanout Cable

1-to-8 SAS 4.0 fanout cable

This Fervit cable converts a single SFF8654 8i 74pin Slimline SAS 4.0 host port into eight SATA 7pin target connectors. It is built for RAID controllers that need to expand drive counts in enterprise storage arrays and NAS systems. The 50cm length suits tidy internal routing in standard rackmount servers and dense enclosures. Server-grade shielded wiring reduces crosstalk for reliable long-term operation.

Capacity and headroom

The eight SATA 7pin outputs support multiple HDDs, SSDs and high-capacity storage devices from one host port. Bandwidth is shared across all active drives, so aggregate throughput depends on the controller and the number of simultaneous transfers. Performance scales with SAS 4.0 signalling but saturates when combined drive demand exceeds the single upstream link. Builders needing more than eight targets or dedicated bandwidth per drive must add additional host ports.

Slimline SAS 4.0 interface limits

The SFF8654 8i connector carries four lanes of SAS 4.0 traffic to the fanout split. Each SATA target operates at its native link speed within that shared upstream capacity. Cable length is fixed at 50cm, limiting placement to adjacent backplanes or drive cages. The design targets internal server chassis only and is not suited for external enclosures or longer runs.
