Dynamode External USB3.0 Dual RAID Encloure User Manual www.dynamode.com
1. Introduction Congratulations on the purchase of your new USB3.0 Dual RAID Encloure This high-performance, extremely flexible RAID (Redundant Array of Independent/Inexpensive Disks) subsystem is ideally suited for integration with databases, imaging systems and e-mail and Web servers. RAID 1 technology is one of the best means to protect your data, while providing greater data integrity and availability than standard hard disk storage. With the single error detection and redundant information to recover the original if a disk fails, a RAID system is an ideal tools to safe-guard valuable data while also stream-lining performance. The USB3.0 Dual RAID Encloure is ability to manage various RAID levels (0, 1,, and JBOD). 1.1. The Capabilities of this device Supports Normal, BIG, Raid 0(Fast),Raid 1(Safe). Support newest SATA-II 3.0Gbps technology. SATA Port Multiplier function is needed. Easy installation on your PC Support USB 3.0 & SATA II Interface 2.

e. Power switch: when switch it to I to power on, and switch to O to power off. f. USB 3.0 interface: USB 3.0 data transfer interface is for USB to connect with computer. g. MODE: set switch for hard disk composite mode. Please refer 3.2 for detail. h. RESET: reset switch, for set up hard disk RAID mode. 3. Setup your device 3.1 The assembling procedure pls. Follow the direction to setup your device. Step 1. Draw the main HDD Holder from the case after uninstall the screws at the back side. Step 2. Install the HDD guide by the attached screws. Step 3. Insert the HDD holder into the case Step 4. Install the screws at the back side. 3.2 RAID set up compare list Item S/W 1 S/W 2 RAID MODE statement 1 OFF OFF Normal Normal mode, show 2 hard disk volumes 2 OFF ON JBOD JBOD mode, show 1 hard disk volumes 3 ON OFF RAID0 RAID0 mode, show 1 hard disk volumes 4 ON ON RAID1 RAID1 mode, show 1 hard disk volumes - 3 -
3.3 The Switch Setting Please backup your data on hard disk before using this product, as the data on hard disk may lost when change to new mode, you can set mode refer to the compare list and sketch map. 1. When power off: Set 1, 2 in MOD position according to compare list, to set the mode to you want, and then power on, It will be enter into new hard disk mode. 2. When power on and the machine is running: Please set 1, 2 in MODE position according to compare list first. then press RESET, the mode will be exchanged to the new one you set. Attention: when you will change it to other mode from RAID1 mode, you have to set RAID0 mode first and then to the one you want. Normal: A storage policy that grants the host computer direct access to a physical disk drive. With Normal, the number of available virtual drives is equal to the number of physical drives. JBOD: A storage policy configuration in which multiple physical hard disk drives are concatenated and treated as one large volume. This configuration allows the end-user to increase logical volume size beyond the capacity of individual hard disk drives.. RAID0(FAST): A storage policy in which I/O processing is balanced evenly in a method known as striping, equivalent to RAID 0. Striping increases storage operation speed as each portion of data is divided into segments that are written to different disks simultaneously. FAST offers the best performance in terms of speed, but has no redundancy of data. - 4 -
RAID1(SAFE): To implement the SAFE storage policy, the Basic Configuration Wizard creates two volumes. Each volume consists of two hard disk drives that mirror each other. The remaining hard disk drive is specified as a Hot Spare for both volumes. - 5 -
