1. Introduction
The EliteRAID RAID Storage Subsystem is a high-performance SATA ll
drive bus disk array controller. When properly configured, the RAID
conntroller can provide non-stop service with a high degree of fault
tolerance through the use of RAID technology and advanced array
management features. The RAID controller unleashes a truly innova-
tive eSATA (3.0Gbps)/USB2.0 solution for use with your PC and Mac.
The HOST interface on the host may be located either on the system
board, or on a plug-in host bus adapter (HBA) card. With the host
SATA controller supported port multiplier function, eSATA host chan-
nel can support multiple volumes (up to 8) per channel. USB2.0 host
channel can also support up to 16 volumes. Up to 16 volumes can be
created on each EliteRAID RAID Storage Subsystem.
The RAID conntroller allows easy scalability from JBOD to RAID. It can
be configured to RAID levels 0, 1, 10, 1E, 3, 5, 6, Single Disk or JBOD.
The RAID function allows one HDD failure without impact on the exist-
ing data and failed drive data can be reconstructed from the remaining
data and parity drives. RAID configuration and monitoring can be done
through the rear LCD control panel, serial port or LAN port. The con-
troller unit is most cost-effective SATA disk drive RAID conntroller with
completely integrated high-performance and data-protection capabili-
ties, which meet the performance and features of a midrange storage
product at an entry-level price.
1.1 System Architecture
1.1.1 eSATA/USB 2.0 Host Interface
The EliteRAID RAID Subsystem host interface appears to the host
system as a SATA ll or UBS2.0 target device. Your EliteRAID RAID
subsytem uses the latest eSATA technology, allowing interface
(or bus) transfer rates of up to 3.0Gbps. The eSATA was device
