DP-503-F4A3 RAID SUBSYSTEM 1.3 RAID Concepts RAID Fundamentals The basic idea of RAID (Redundant Array of Independent Disks) is to combine multiple inexpensive disk drives into an array of disk drives to obtain performance, capacity and reliability that exceeds that of a single large drive. The array of drives appears to the host computer as a single logical drive.
Page 14
DP-503-F4A3 RAID SUBSYSTEM RAID 0 is typically defined as a group of striped disk drives without parity or data redundancy. RAID 0 arrays can be configured with large stripes for multi-user environments or small stripes for single- user systems that access long sequential records. RAID 0 arrays deliver the best data storage efficiency and performance of any array type.
Page 15
DP-503-F4A3 RAID SUBSYSTEM of drive failure, data recovery is accomplished by calculating the exclusive OR (XOR) of the information recorded on the remaining drives. Records typically span all drives, which optimizes the disk transfer rate. Because each I/O request accesses every drive in the array, RAID 3 arrays can satisfy only one I/O request at a time.
DP-503-F4A3 RAID SUBSYSTEM main advantage of RAID 6 is High data availability – any two drives can fail without loss of critical data. Dual-level RAID achieves a balance between the increased data availability inherent in RAID 1 and the increased read performance inherent in disk striping (RAID 0). These arrays are sometimes referred to as RAID 0+1.
DP-503-F4A3 RAID SUBSYSTEM the subsystem are shown below. RAID Description Min. Drives Level Block striping is provide, which yields higher performance than with individual drives. There is no redundancy. Drives are paired and mirrored. All data is 100% duplicated on an equivalent drive. Fully redundant.
DP-503-F4A3 RAID SUBSYSTEM A topology defines the interconnection scheme. It defines the number of devices that can be connected. Fibre Channel supports three different logical or physical arrangements (topologies) for connecting the devices into a network: Point-to-Point Arbitrated Loop(AL) Switched (Fabric) The physical connection between devices varies from one topology to another.
DP-503-F4A3 RAID SUBSYSTEM The following elements are the connectivity of storages and Server components using the Fibre channel technology. Cables and connectors There are different types of cables of varies lengths for use in a Fibre Channel configuration. Two types of cables are supported: Copper and Optical (fiber). Copper cables are used for short distances and transfer data up to 30 meters per link.
DP-503-F4A3 RAID SUBSYSTEM A Raid Set is a group of disk drives containing one or more logical volumes called Volume Sets. It is not possible to have multiple Raid Sets on the same disk drives. A Volume Set must be created either on an existing Raid Set or on a group of available individual disk drives (disk drives that are not yet a part of a Raid Set).
DP-503-F4A3 RAID SUBSYSTEM RAID 0 and RAID 1 Volume Set can be used immediately after the creation. But the RAID 3, 5 and 6 Volume Sets must be initialized to generate the parity. In the Background Mode initialization, the initialization proceeds as a background task, the Volume Set is fully accessible for system reads and writes.
DP-503-F4A3 RAID SUBSYSTEM 1.5.3.4 Online RAID Level and Stripe Size Migration User can do migration on both the RAID level and Stripe Size of an existing Volume Set while the server is online and the Volume Set is in use. Online RAID level/stripe size migration can prove helpful during performance tuning activities as well as in event that additional physical disks are added to the RAID subsystem.
DP-503-F4A3 RAID SUBSYSTEM a Raid Set can be defined as a hot spare drive. Hot spares permit you to replace failed drives without powering down the system. When the RAID subsystem detects a drive failure, the system will do automatic and transparent rebuild using the hot spare drives. The Raid Set will be reconfigured and rebuilt in the background while the RAID subsystem continues to handle system request.
DP-503-F4A3 RAID SUBSYSTEM 1. Attach network cable to the R-Link port and connect the other end of network cable to your network hub/switch. Or as alternative for configuration, you may connect the serial cable to the Monitor port and to the serial port of your host/server.

Page 53
DP-503-F4A3 RAID SUBSYSTEM Migration occurs when a Volume Set migrates from one RAID level to another, a Volume S et stripe size changes, or when a disk is added to a Raid Set. Migrating status is displayed in the Volume S e t status area of the RaidSet Hierarchy screen during migration.
DP-503-F4A3 RAID SUBSYSTEM 3.7.5 Check Volume Set Use this function to perform Volume Set consistency check, which verifies the correctness of redundant data (data blocks and parity blocks) in a Volume Set. This basically means computing the parity from the data blocks and comparing the results to the contents of the parity blocks, or computing the data from the parity blocks and comparing the results to the contents of the data blocks.
DP-503-F4A3 RAID SUBSYSTEM 3. Tick on Confirm The Operation and click on the Submit button. The Checking process will be started.
