Chapter 1 EvoStor-400CA Overview
1.1 Introduction
RAID (Redundant Array of Inexpensive Disks) is a group of disk drives combined
with two or more hard disks, accompanied with software and controller to provide
a high performance of data transfer at relatively low cost. More and more users
are employing RAID for disk configuration to obtain a high transfer rate of data as
well as secure data protection. As two or more disks are used in RAID
configuration, disk data can be stored and backed up more conveniently.
1.2 Product Overview
EvoStor-400CA (hereafter referred as EvoStor) external RAID system is designed
to offer high performance, high reliability and low cost alternatives to SCSI to IDE
RAID subsystems. It utilizes cost-effective IDE drives with simple storage setup
and management process making it ideal for small to mid-sized companies and
departments.
System Features
• Intel 64-bit RISC I/O Processor
• Built-in 128 MB cache memory, expandable up to 1 GB
• Compatible with all SCSI-3 and SCSI-2/LVD host adapters up to 160 MB/s
• LCD panel for easy RAID configuration and status monitoring
• EvoStor Management Technology: Windows-based utility monitors status of
RAIDs through in-band SCSI command, enable remote management
• Supports up to 4 hot-swappable Ultra DMA 133 hard drives
• Local audible event notification buzzer
• Real time drive activity and status indicators
• Supports RAID levels 0, 1, 0+1, 3, 5 and NRAID
• Supports multiple logic volume creation, each logic volume could be
configured as one RAID level independently
• Supports hot spare and automatic hot rebuild
• Transparent data transfer for all popular operating systems

2.2 Installation
Follow the steps below to install EvoStor system:
1. Unpack EvoStor package.
2. Install hard disk. (Skip this step if a hard disk is included in the package).
Note: Set the jumper of the hard disk in Master mode before installation.
3. Connect the power cable.
4. Turn on EvoStor. Upon successful switching on of the system, the following
message will be displayed on the LCD panel.
Note: Please refer to Appendix C for further information on symbols of
disk channel status.
5. Set the SCSI ID for EvoStor via the LCD panel if the ID duplicates with other
SCSI devices.
6. Create disk volume via the LCD panel. If you configure EvoStor as RAID 1,
0+1, 3, or 5, the percentage of initialization will be shown. Complete
initialization before proceeding to step 7.
Note: Please select LUN0 as the ID for this logic volume, as some O.S.
are not able to recognize logic volume ID other than LUN0. For
information about creating more than one logic volume, please contact the
O.S. distributor. For more details on Steps 5 and 6, please refer to
Chapter 3.1.2.

computer via a SCSI cable.
8. Turn on the host computer. In the startup screen of BIOS, it will be shown
that EvoStor is detected. Note that if you create the logic volume on LUN0,
EvoStor RAID Controller resided on LUN0 will not be shown.
9. Skip the following steps if the above logic volume is resided on LUN0. After
Windows starts, the Found New Hardware Wizard will appear.
