1.1 INTRODUCTION
Thank you for choosing EliteRAID ER104UT(-B) storage appliance. It is a hardware RAID solution for digital home and small
office storage appliances. Features of the EliteRAID ER104UT(-B) include advanced RAID modes. Simply connect the
appliance with an appropriate USB or eSATA cable to the USB host or PCIe 1x controller card. eSATA bracket cable is
provided to connect to motherboard if no PCIe slot avaliable.
The EliteRAID ER104UT(-B) storage appliance are available in eight different configurations (Clean, Large, Clone, R0, R1, R10,
R3 and R5), each offering a different application of features and capabilities.
The EliteRAID ER104UT(-B) Storage Processors are powered by hardware RAID chip, 1 to 5-ports 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. It is a self-contained storage processor chip which completely frees up the main CPU
loading and the SATA ports comply with eSATA specification, the USB ports comply with Hi-Speed USB specification,
making it suitable for use in external storage applications.
The EliteRAID ER104UT(-B) storage appliance uses industry-proven Multi-port Serial ATA PHY technology and proprietary
storage processor to provide very high efficient SATA RAID operation.
With an easy configuration scheme, the device can be a pure port-multiplier which provides SATA port expansion just like
a SATA 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. EliteRAID
ER104UT(-B) storage appliance also has advance mode to provide both benefit of performance boost and data protection.
