Fervit SFF8643 to 4×SFF8482 SAS breakout cable

SKU CH-3TB4-6AMV2

Converts a single SFF8643 Mini SAS HD host port into four 29pin SFF8482 SAS/SATA drive ports supporting 12Gbps SAS 3.0 data transmission for multi-drive server expansion

  • Converts one SFF8643 port to four 29pin SFF8482 drive connections
  • Delivers 12Gbps SAS 3.0 throughput for enterprise HDDs and SSDs
  • Optimised wire harness maintains low signal loss across multiple drives
  • Servergrade construction withstands continuous rackmount operation
  • Plugandplay compatibility with HD1 host adapters and RAID controllers

Breakout Cable for SFF8643 Host Ports

This Fervit cable converts a single SFF8643 Mini SAS HD host port into four 29-pin SFF8482 drive connectors. It supports 12Gbps SAS 3.0 data transmission for enterprise-grade HDDs, SSDs and RAID storage systems. The 1-to-4 breakout design enables multi-drive server expansion from one host adapter slot.

Suited for SAS or SATA drive arrays.

Builders expanding rackmount servers or storage backplanes with SAS or SATA hard drives will find the pinout matches HD1 host adapters and RAID controllers. The optimised wire harness maintains signal integrity across all four ports during continuous operation. Systems lacking an SFF8643 host connector cannot use this cable.

Deciding spec: single SFF8643 to four SFF8482 ports

The cable presents one SFF8643 Mini SAS HD plug and four 29-pin SFF8482 receptacles rated for SAS 3.0 speeds. Verify that your host adapter or RAID card exposes an SFF8643 port and that each target drive accepts the SFF8482 interface. No other connector combination is supported by this assembly.

Questions about this item

Will the SFF8643 connector or the four SFF8482 ends need periodic replacement?

The cable uses server-grade construction rated for continuous operation in rackmount servers and storage backplanes, so no scheduled connector replacement is required.

What limits throughput first when all four drives run sustained 12Gbps SAS 3.0 traffic?

The single SFF8643 host port aggregates four 12Gbps lanes, so the host controller bandwidth becomes the bottleneck before the cable signal integrity degrades.

How much heat or extra power draw does the breakout add during all-day RAID array rebuilds?

The passive wire harness adds no active components, so it contributes negligible heat and draws no power beyond the drives and controller themselves.
