Adaptec Mini SAS HD Fan-Out Cable

The Adaptec 2279800-R is an internal cable that splits a Mini Serial Attached SCSI HD x4 (SFF-8643) port into four individual Serial ATA connectors. It includes sideband signals (SFF-8448) and measures 0.8 metres (2.62 ft) in length. The black cable connects a SAS/SATA adapter or backplane to SATA drives.

Suited for SAS Adapter to SATA Drive Links

This accessory suits builders who need to connect a Series 7 or 7Q adapter to SATA disks using a single Mini SAS HD port. It is not for systems that require a direct Mini SAS HD to Mini SAS HD link, nor for installations needing a different cable length or connector type.

Key Specification: SFF-8643 to Four SATA

The defining feature is the SFF-8643 Mini SAS HD plug fanning out to four SATA plugs with SFF-8448 sideband support. Verify that your adapter and drives use this exact connector combination before purchase.

Questions about this item

Will the SFF-8448 sideband wires on the 2279800-R need periodic reseating?

The sideband conductors are crimped into the SFF-8643 and SATA plugs; no user-serviceable contacts exist, so reseating is not required unless a connector is physically damaged.

Does the 0.8 m length limit signal quality on a 6 Gb/s SAS link?

The cable is built to the SFF-8643 specification for 6 Gb/s operation; at 0.8 metres it stays well within the electrical budget for that speed.

Does the cable generate noticeable heat when four SATA drives run continuously?

Passive copper conductors carry only the drive signals and low-current sideband lines, so the cable itself produces no measurable heat during all-day operation.
