1-Getting Started The RAIDBank4 interface components The following figures illustrate the connector locations for the RAIDBank4.
1-Getting Started Communication and Control RAID functions including creation, modification, and monitoring can be accomplished through the LCD Control panel or the web based administration user interface. The LCD status panel informs you of the RAIDBank4’s current MicroNet Tech operating status at a glance, as shown here: LED Normal Status Problem Indication Power LED (Front) LED glows bright green Dark or blinking red on system error.
1-Getting Started Connecting the RAIDBank4 Connecting the RAIDBank4 requires an available power socket, and a host with one of the following interfaces: • A USB 2.0 port • An external SATA host bus connector with large LUN and port multiplier support • The Ethernet remote management requires an available Ethernet jack to a hub or switch on your network. 1. Plug the AC adapter cord into the power port on the back of the drive. The plug should not require much effort to insert.
1-Getting Started RAID System Management Controls Following the hardware installation, the RAIDBank4 must be configured and the volume set units initialized before they are ready to use. This can be accomplished by one of the following methods: Note: • Front panel touch-control keypad The RAIDBank4 allows only one method to access menus at a time.
2-Understanding RAID Chapter 2. Understanding RAID The RAIDBank4 controller subsystem is a high-performance SATA2 drive bus disk array controller. When properly configured, the RAIDBank4 can provide non-stop service with a high degree of fault tolerance through the use of RAID technology and advanced array management features. The RAIDBank4 can be configured to RAID levels 0, 1, 10, 3, and 5, as well as disk spans and direct mapping.
2-Understanding RAID RAID 0 (Striping) This RAID algorithm writes data across multiple disk drives instead of just one disk drive. RAID 0 does not provide any data redundancy, but does offer the best high-speed data throughput. RAID 0 breaks up data into smaller blocks and then writes a block to each drive in the array.
2-Understanding RAID RAID 3 RAID 3 provides disk striping and complete data fault tolerance though a dedicated parity drive. RAID 3 breaks up data into smaller blocks, calculates parity on the blocks, and then writes the blocks to all but one drive in the array. The parity data created is then written to the last drive in the array. If a single drive fails, data is still available by computing the inverse operation on the data and parity of the contents corresponding strips of the surviving member disk.
2-Understanding RAID Volume Set A Volume Set is seen by the host system as a single logical device. It is organized in a RAID level with one or more physical disks. RAID level refers to the level of data performance and protection of a Volume Set. A Volume Set capacity can consume all or a portion of the disk capacity available in a RAID Set. Multiple Volume Sets can exist Free Space on a group of disks in a RAID Set.
2-Understanding RAID Hot Swappable Disk support Your RAIDBank4 has a built in protection circuit to support replacement of disk drives without having to shut down or reboot the RAID. In case of drive failure, the failed drive can be removed from the RAIDBank4 and replaced with a new drive without disrupting dataflow to the host computer.

6-Troubleshooting Frequently Asked Questions General FAQ Q: Can I leave my RAIDBank4 on all the time, or should I turn it off when not in use? A: The RAIDBank4 is meant to be left on, but does not add any limitations on being turned off. Drive reliability is definitely affected by repeated power cycles, and the RAIDBank4 cannot alleviate this.
6-Troubleshooting Q: I’m trying to access the RAIDBank4 using the front panel. When I push enter, it asks me to verify the password. I defined a password, and I enter it, but then the ENT key just moves the cursor over another space and the arrow keys change the characters to use and the ESC take me back to the IP Address screen. A: Please press the ENT key to move the cursor over another space until the end of the password line is reached (16 character including space) to confirm the password.
6-Troubleshooting Windows related FAQ: Q: I do not see my Drive listed in the My Computer window, but it does appear in the Device Manager list. A: Right-click on My Computer. Select Manage in the pop-up menu. In the Computer Management window, select Storage, then select Disk Management. In the Disk Management window, you should see a list of available storage devices. Look for the Disk that has a capacity closest to your RAIDBank4 volume(s).
6-Troubleshooting Q: When I leave my computer idle for a while, my Drive won’t work properly. A: The most likely cause is that your computer is going into sleep mode. The immediate solution is to shut down your computer and turn off the Drive, and then restart your computer. Once your computer is completely booted up, turn on the Drive. You should see the drive in the Windows Explorer. To prevent this problem from recurring, open the “Power Settings/Energy Saver” and set it to never go into sleep mode.

D-Glossary Appendix D- Glossary ATA Acronym for “AT Bus Attachment” - a standard interface to IDE hard disks. Western Digital’s IDE disk interface was standardized by ANSI to form the ATA specification using a 16-bit ISA bus. Cache cache is a fast-access memory bank that serves as an intermediate storage for data that is read from or written to secondary storage. Typically, high-speed caches are implemented in RAM, though they can also be implemented on disk when speed is not a critical requirement.
D-Glossary Driver A piece of software that controls a hardware device. Typically drivers provide an interface by which applications can use the device in a uniform and hardware-independent manner. DHCP (Dynamic Host Configuration Protocol) a protocol that lets network administrators manage centrally and automate the assignment of IP (Internet Protocol) configurations on a computer network.
D-Glossary Logical Unit (LUN) a SCSI protocol entity which may be addressed by the actual input/ output (I/O) operations of a Logical Drive. Each SCSI-type target provides one or more logical units. Native Command Queuing (NCQ) a technology designed to increase performance of SATA hard disks by allowing the disk firmware to internally optimise the order in which read and write commands are executed.
D-Glossary Performance Performance is an important criterion on which a customer judges a RAID controller. There are a number of popular benchmarking utilities that are available to measure the I/O performance of a controller. Some of these utilities simulate specific real-life applications and provide the user a score indicating the controller’s overall performance in that niche.
D-Glossary on the parity disk and the remaining functioning disks. Consequently read operations can be time-consuming when the array is operating in degraded mode. If the parity disk itself fails, then the RAID array is not affected in terms of I/O throughput but it no longer has protection from additional disk failures. Also, a RAID 3 array can improve the throughput of read operations by allowing reads to be performed concurrently on multiple disks in the set.
D-Glossary Read Ahead Motivated by the principle of “spatial locality”, many RAID controllers read blocks of data from secondary storage ahead of time, i.e., before an application actually requests those blocks. The number of data blocks that are read ahead of time is typically governed by some heuristic that observes the pattern of requests. The read-ahead technique is particularly efficient when the spatial distribution of an application’s requests follows a sequential pattern.
D-Glossary SCSI acronym for “Small Computer System Interface”, SCSI is a set of standards for physically connecting and transferring data between computers and peripheral devices. The SCSI standards define commands, protocols, and electrical and optical interfaces. SCSI is most commonly used for hard disks and tape drives, but it can connect a wide range of other devices, including scanners and CD drives. Most modern storage protocols are based on the SCSI Block Protocol.
