Serial Attached SCSI (SAS) is a high-speed data storage interface designed for high-throughput and fast data access.

Intended primarily for data storage centers the SAS interface is backwards compatible with SATA.

This allows the user to mix more expensive lower-capacity SAS drives for applications that require faster data access and higher reliability with lower-cost higher-capacity SATA drives for applications with lower access speed requirements.

Description

It has a single 36-pin SFF-8087 male Mini-SAS plug (with locking latch) on one end and has four 7-pin SATA female plugs (with locking latches) on the other allowing you to connect four SATA drives to an SAS controller.
Internal mini SAS SFF-8087 to (4) SFF-8482 connectors with SATA power.
SFF-8482 side has a 15-pin power connector.
This cable allows you to connect from a SAS controller with SFF-8087 internal mini SAS connector to four (4) SAS hard drives.
This is a Forward Breakout cable meaning that it is intended to connect to a host/controller on the SAS end and to drives on the SATA end.

Compatible with the following for IBM controller as well as others controllers:
