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

• 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
