eRAID - DAT Optic Ext. RAID System with USB2.0, Serial ATA, FireWire 400/ 800 Interfaces

| Summary | Description | Specifications | Notes |

High-perform architecture RAID controller
The eRAID System provides RAID levels 0, 1, 0+1, 3 and 5 or JBOD configurations with featuring of 1394a; 1394b, USB2.0 and Serial ATA connectivity. Our eRAID system utilizes high-performance 64bit RISC processor, 64bit memory architecure, built-in 64MB SDRAM cache buffer and 66MHz/32bit path at burst rate upto 266MB/sec to control five (5) hot-swapt ATA-133 HDD (no size limited) with unprecedented performance whether Share or Independent Volume configuring thru Serial ATA, USB2.0 and/or 1394a/b

Clustering feature
Built-in two independent data paths our eRAID is the ONLY external (portable) RAID system with offering the un-parallel clustering feature. As USB2.0 and FireWire ports configure with channel 0 (data path), where other independent channel 1 move data thru Serial ATA. Therefore two different computer systems (clustering feature required) can access the data in our eRAID. To use this feature please refer to notes below.

Easy configuration
With eRAID system, RAID level 0, 1 (0+1), 3, 5 and JBOD can be Controlled and managed through LCD control front panel or by a platform-independent embeded management utiltiy through RS-232 or USB port. This platform-independent method allows end-user (IT) implementing VT-100 console and/or HTTP proxy browser-base utility.

Redundant Flash Image
Firmware mirror provides a unipue redundancy feature, which ensures the system controller availability

RAID Capabilities
Online RAID Expansion; Online RAID Level and Stripe Size Migration; Automatic Failed Driver Detect and Rebuilding; Global Online Spare; HDD Hop-swap, Instant Availability and Background Initialization.

eRAID system is the most cost-effective IDE disk drive array upto 2.5TeraByte system, with completely integrated high performance and data protection capabilities, which are easily hot-plug/integrated into servers and workstations. It can also meet and exceed the rapidly growing demand from the Small to Medium Enterprise and Audio/Video Editing market.

Please note eRAID configures
Channel 0 = USB2.0 and FireWire 400/800 (default)
Channel 1 = Serial ATA

For Channel 1= Serial ATA to work, the system needs to set Channel 1 ON, or Cluster Mode (Channel 0&1 are on) then All ports would work.
Here is how to set it thru LCD

1. Press ENTER
2. Verify Password - Enter your password (Default asss word is 0000 - four zeros).
   Use Up/Down Arrow button to scroll
3. Go to Quick Volume and RAID Set up
4. Go to Volume Set Functions
5. Go to Modify Volume Attribute
6. Select RAID set # xx
7. Select Volume Set # xx
8. Go to Change IDE channel
9. Select Ch0&1 Cluster
10. Reset the system
