1-meter Mini SAS HD SFF-8643 male to four SFF-8482 fan-out cable, braided jacket

SMUGDESK

SMUGDESK Mini SAS HD SFF-8643 to 4×SFF-8482 12Gbps SAS Cable

SKU CH-ZGC6-PTFXN

A Mini SAS HD SFF-8643 male connector splits into four SFF-8482 ports for simultaneous SAS drive connections at 12Gbps

  • Fan-out design splits one SFF-8643 port into four SFF-8482 drive connections
  • 12Gbps SAS 3.0 bandwidth keeps enterprise storage arrays running at full speed
  • One-metre length allows tidy internal routing inside servers and NAS chassis
  • Shielded construction suppresses crosstalk and EMI for stable 24/7 operation
  • Compatible with SAS RAID HBA cards, hard drives and SSDs for storage expansion

Internal SAS fan-out cable

This SMUGDESK Mini SAS HD SFF-8643 breakout cable connects a single RAID or HBA controller port to four SAS hard drives or solid-state drives. It is built for system integrators and server administrators who need to expand internal storage inside workstations, NAS chassis or surveillance arrays. The 1-meter shielded assembly supports the SAS 3.0 standard at 12Gbps.

Practical limits of SAS 3.0

The cable carries data signals only and must plug into a RAID controller or host card, not a backplane. Shielded construction reduces crosstalk and electromagnetic interference to maintain stable 24/7 operation. Each of the four SFF-8482 ports operates independently within the shared 12Gbps host link.

SFF-8643 to four SFF-8482 connectors

Verify that your controller presents an SFF-8643 Mini SAS HD 29-pin male interface and that your drives use SFF-8482 29-pin SAS ports before ordering. The fan-out design serves builds requiring four drive connections from one controller slot. It does not support configurations needing a backplane attachment or a different host connector type.

Questions about this item

Should I choose this fan-out cable or a straight-through Mini SAS HD cable for my RAID card?

Pick this SFF-8643 to 4×SFF-8482 breakout when your RAID controller has a single Mini SAS HD port and you need to attach up to four individual SAS drives; use a straight-through cable only if both ends are Mini SAS HD.

What does the 12Gbps rating mean once the cable is installed in my server?

It indicates the cable meets the SAS 3.0 specification, so each of the four SFF-8482 lanes can carry up to 12Gbps provided the RAID card, drives and backplane all support that speed.

Which SAS standard does the SFF-8643 connector follow and what does it cap in practice?

The SFF-8643 host end follows the SAS 3.0 specification, limiting each lane to 12Gbps and preventing faster SAS 4.0 or 24Gbps operation even if the controller supports it.
