Manufacturer: Maxim Integrated (now Analog Devices)

General Description

The VSC7177 is a Serial ATA and Serial Attached SCSI multiplexer/buffer that implements a 2:1 port selector function for 1.5 Gbps and 3.0 Gbps links.

This function is used when dual hosts, such as I/O controllers, must access single-port disk drives in high availability storage subsystems where redundancy and load sharing are important.

The outputs from the I/O controllers are multiplexed to a Serial ATA or Serial Attached SCSI drive.
