1.0 INTRODUCTION
The EXAR XRS10L140 is a Serial ATA port multiplier designed for next generation enterprise class disk array systems that use SATA mid-planes. The device is targeted at low cost storage applications.
This function is used when one active host has to communicate with multiple SATA drives. The XRS10L140 supports up to 4 SATA drives and utilizes the full bandwidth of the host connection.
The upstream ports of XRS10L140 can also be attached to a port selector (XRS10L20) or a Serial ATA Switch to provide redundancy in a more complex topology.
The XRS10L140 includes enhanced features such as staggered HDD spin-up, power management control, hot plug capability and support for legacy software.
