Areca SlimSAS x8 STR SFF8654 a 2x MiniSAS HD x4 SFF8643 100cm

In high-density server racks and storage arrays, connecting a host bus adapter with a SlimSAS x8 port to two separate MiniSAS HD x4 devices often requires multiple adapters. This Areca breakout cable eliminates that complexity: a single 100 cm lead splits the 8-lane SlimSAS SFF-8654 connector into two independent 4-lane MiniSAS HD SFF-8643 connectors, each capable of driving a separate drive enclosure or backplane. IT administrators and system integrators can now link a single HBA or RAID controller to two storage targets without signal loss or cable clutter.

Key specifications

• Host connector: SlimSAS x8 (SFF-8654), straight orientation
• Device connectors: 2x MiniSAS HD x4 (SFF-8643)
• Lane configuration: 8 lanes to 2x 4 lanes
• Cable length: 100 cm (3.3 ft)
• Supported protocols: SAS (Serial Attached SCSI) and NVMe (PCIe)
• Maximum data transfer rate: 24 Gbps per lane (up to 192 Gbps total host bandwidth)
• Impedance: 100 Ohm
• Colour: Black

Why choose it

Engineered for signal integrity, this cable uses precision-matched 100 Ohm impedance to maintain reliable data transfer at 24 Gbps per lane. The straight SlimSAS connector fits easily into standard server brackets, while the two MiniSAS HD ends offer flexible routing to separate storage devices. The 100 cm length provides enough reach for clean cable management without excessive slack, reducing airflow obstruction in dense racks. Areca's manufacturing quality ensures consistent performance in demanding enterprise environments.

Ideal use cases

• Connecting a single SlimSAS x8 HBA or RAID controller to two MiniSAS HD x4 drive enclosures
• Expanding storage connectivity in 2U/4U rack servers with limited PCIe slots
• Linking a host to NVMe or SAS backplanes that use SFF-8643 connectors
• Simplifying cable routing in high-density storage arrays and JBODs
• Replacing multiple single-lane cables with one consolidated breakout solution

Good to know

This cable is backward compatible with SAS 12G and earlier SAS generations, as well as PCIe Gen3/Gen4 NVMe signalling. It is not intended for direct connection to SATA drives without appropriate interposers. The black jacket is durable and flexible, suitable for repeated re-routing during hardware maintenance. Always verify that your host controller supports x8 bifurcation to two x4 ports before deployment.
