JMB322 RAID Port Multiplier
Overview
The JMicron JMB322 is a single chip, 1 to 2-port Serial ATA II Port Multiplier with RAID function
support. It is designed to provide SATA port expansion, data protection and performance aggregation at
various applications.
The device uses JMicron’s production-proven Multi-port Serial ATA PHY technology and
JMicron-proprietary storage processor to provide very high efficient RAID operation. With an easy
configuration scheme, the device can be a pure port multiplier which provides SATA port expansion
just like USB Hub, or hard-drive performance booster which provides a high performance device seen
by host controller or hard-drive data protector which automatically backup data to prevent data loss
from hard-drive damage.
The JMB322 is a self-contained storage processor chip which completely frees up the main CPU
loading and the SATA ports comply with eSATA specification, making it suitable for use in both
internal and external applications.
