Chapter 1 Introduction The RAID subsystem is a Ultra 320 LVD SCSI-to-Serial ATA II RAID (Redundant Arrays of Independent Disks) disk array subsystem. It consists of a RAID disk array controller and eight (8) disk trays. The subsystem is a “Host Independent” RAID subsystem supporting RAID levels 0, 1, 3, 5, 6 0+1 and JBOD. Regardless of the RAID level the subsystem is configured for, each RAID array consists of a set of disks which to the user appears to be a single large disk capacity.
1.
1.2 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.
By striping the drives in the array with stripes large enough so that each record falls entirely within one stripe, most records can be evenly distributed across all drives. This keeps all drives in the array busy during heavy load situations. This situation allows all drives to work concurrently on different I/O operations, and thus maximize the number of simultaneous I/O operations that can be performed by the array.
RAID 1, also known as disk mirroring, is simply a pair of disk drives that store duplicate data but appear to the computer as a single drive. Although striping is not used within a single mirrored drive pair, multiple RAID 1 arrays can be striped together to create a single large array consisting of pairs of mirrored drives. All writes must go to both drives of a mirrored pair so that the information on the drives is kept identical.
RAID 3 sector-stripes data across groups of drives, but one drive in the group is dedicated to storing parity information. RAID 3 relies on the embedded ECC in each sector for error detection. In the case 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.
RAID 6 is similar to RAID 5 in that data protection is achieved by writing parity information to the physical drives in the array. With RAID 6, however, two sets of parity data are used. These two sets are different, and each set occupies a capacity equivalent to that of one of the constituent drives. The main advantages 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 RAID 5 and the increased read performance inherent in disk striping (RAID 0). These arrays are sometimes referred to as RAID 0+1 or RAID 10 and RAID 0+5 or RAID 50. In summary: RAID 0 is the fastest and most efficient array type but offers no faulttolerance. RAID 0 requires a minimum of two drives. RAID 1 is the best choice for performance-critical, fault-tolerant environments.
RAID Management The subsystem can implement several different levels of RAID technology. RAID levels supported by the subsystem are shown below. RAID Level Description Min Drives 0 Block striping is provide, which yields higher performance than with individual drives. There is no redundancy. 1 1 Drives are paired and mirrored. All data is 100% duplicated on an equivalent drive. Fully redundant. 2 3 Data is striped across several physical drives. Parity protection is used for data redundancy.
1.3 SCSI Concepts Before configuring the subsystem, you must first understand some basic SCSI concepts so that the subsystem and SCSI devices will function properly. 1.3.1 Multiple SCSI Format Support The subsystem support the SCSI interface standards listed below. Note that the data bit and cable length restrictions must be followed.
1.3.3 Terminators Based on SCSI specifications, the SCSI bus must be terminated at both ends, meaning the devices that are connected to the ends of the SCSI bus must have their bus terminators enabled. Devices connected in the middle of the SCSI bus must have their terminators disabled. Proper termination allows data and SCSI commands to be transmitted reliably on the SCSI bus. The host adapter and the SCSI devices attached to it must be properly terminated, or they will not work reliably.
1.4 Array Definition 1.4.1 RAID Set A RAID Set is a group of disks containing one or more volume sets. It is impossible to have multiple RAID Sets on the same disks. A Volume Set must be created either on an existing RAID set or on a group of available individual disks (disks that are not yet a part of an raid set). If there are pre-existing raid sets with available capacity and enough disks for specified RAID level desired, then the volume set will be created in the existing raid set of the user’s choice.
1.4.3 Easy of Use features 1.4.3.1 Instant Availability/Background Initialization 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 Normal Initialization, the initialization proceeds as a background task, the volume set is fully accessible for system reads and writes.
1.4.3.3 Online Capacity Expansion Online Capacity Expansion makes it possible to add one or more physical drive to a volume set, while the server is in operation, eliminating the need to store and restore after reconfiguring the raid set. When disks are added to a raid set, unused capacity is added to the end of the raid set. Data on the existing volume sets residing on that raid set is redistributed evenly across all the disks. A contiguous block of unused capacity is made available on the raid set.
1.4.3.4 Online RAID Level and Stripe Size Migration User can migrate 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 the event that additional physical disks are added to the RAID subsystem. For example, in a system using two drives in RAID level 1, you could add capacity and retain fault tolerance by adding one drive.
1.4.4.2 Hot-Swap Disk Drive Support The RAID subsystem has built the protection circuit to support the replacement of UDMA hard disk drives without having to shut down or reboot the system. The removable hard drive tray can deliver “hot swappable,” faulttolerant RAID solutions at prices much less than the cost of conventional SCSI hard disk RAID subsystems. We provide this feature for subsystems to provide the advanced fault tolerant RAID protection and “online” drive replacement. 1.4.4.
Chapter 2 Getting Started Getting started with the subsystem consists of the following steps: Unpack the storage subsystem. Identifying Parts of the subsystem. Connecting to Host. SCSI Termination. Power on the subsystem. Install Hard Drives. 2.1 Unpacking the Subsystem Before continuing, first unpack the subsystem and verify that the contents of the shipping carton are all there and in good condition.

2.2.2 Rear View HOST A FAN HOST B FAN Power Supply R-LINK Monitor Power Switch Power Input Socket 1. Host Channel A & B The subsystem is equipped with 2 host channels (Host channel A and Host channel B). The host channel with two 68-pin SCSI connectors at the rear of the subsystem for SCSI in and out. 2. R-Link Port : Remote Link through RJ-45 ethernet for remote management The subsystem is equipped with one 10/100 Ethernet RJ45 LAN port.
3. Monitor Port The subsystem is equipped with a serial monitor port allowing you to connect a PC or terminal. 4. Cooling Fan module Two fans are located at the rear of the subsystem. They provide sufficient airflow and heat dispersion inside the chassis. 5. Power Supply Unit The power supply is located at the rear of the subsystem. Turn on the power supply to power-on the subsystem. The “power” LED at the front panel will turn green. 2.
HOST A in HOST B in ! Note: 1. When one or more SCSI devices are connected, the total length of all cables (internal or external) must not exceed 3 meters (9.8 ft.) to ensure reliable operation. 2. For safety reasons, make sure the Disk Array and Host Computer are turned off when you plug-in the SCSI cable.
2.4 SCSI Termination Two 68-pin wide SCSI connectors are provided on the back of the enclosure for connecting the array to the system. These connectors are used in one of two ways: If the disk array is the only external SCSI device, or is the last external device in a daisy-chained configuration, connect the incoming cable (the one which is attached to the SCSI adapter) to the Host A & B in connector and install the external SCSI Terminator on the Host A & B out connector.
Correct SCSI termination procedures require that the last devices on the SCSI bus be terminated. If the last device is not terminated, or if devices other than the last are terminated, erratic SCSI bus performance may occur. Typically, the system or host adapter (SCSI card inside the PC) is the first device and is already terminated. When installing the disk array on a SCSI bus with other devices, be sure to observe the above rules with all devices on the SCSI bus.
2.5 Powering-on the Subsystem When you connect the Disk Array to the Host computer, you should press the ON/OFF Power Supply Switch. It will turn the Disk Array on and the Self-Test will be started automatically. 1. Plug in the power cord or power connector located at the rear of the subsystem. Power Input Socket ! Power Switch Note: The subsystem is equipped with PFC (power factor correction), Full Range power supply. The subsystem will automatically selector voltage. 2. Turn on the power. 3.
2.6 Install Hard Drives This section describes the physical locations of the hard drives supported by the subsystem and gives instructions on installing a hard drive. The subsystem supports hot-swapping allowing you to install or replace a hard drive while the subsystem is running. 1. Each Drive Tray has a locking mechanism. When the Lock Groove is vertical, this indicates that the Drive Tray is unlocked. When the Lock Groove is horizontal, then the Drive Tray is locked.
! Note: When removing the Drive Tray Module from the enclosure, handle with care to prevent dropping the module. 4. To install the hard drive into the Drive Tray, first insert the hard drive as show below. 5. Turn the Drive Tray over. Notice the 4 screws. Tighten these 4 screws to firmly secure the hard drive to the Drive Tray. 6. To install the trays, insert the trays into the enclosure and close the Drive Tray handle. Then lock the Drive Tray using a screw driver.

3.7 Volume Set Function 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 on a group of disks in a raid set. Additional volume sets created in a specified raid set will reside on all the physical disks in the raid set.
Volume Name: The default volume name will always appear as Volume Set. #. You can rename the volume set name providing it does not exceed the 16 characters limit. Raid Level: Set the RAID level for the Volume Set. Highlight Raid Level and press Enter. The available RAID levels for the current Volume Set are displayed. Select a RAID level and press Enter to confirm. Capacity: The maximum volume size is default in the first setting. Enter the appropriate volume size to fit your application.
to two tera bytes only. A patch driver is needed to enable the system to detect over two tera bytes. Please contact your vendor for supporting. 4K Block: the max. size 16TB , just use with “ basic disk manager “ under OS Window 2000, 2003 or XP. Noted that can’t be used by with dynamic disk manager. InitializationMode: Set the Initialization Mode for the Volume Set. Foreground mode is faster completion and background is instant available. No init mode is for rescuing volume.
SCSI ID: Each SCSI device attached to the SCSI card, as well as the card itself, must be assigned a unique SCSI ID number. A Wide SCSI channel can connect up to 15 devices. The RAID subsystem is as a large SCSI device. We should assign an ID from a list of SCSI IDs. SCSI LUN: Each SCSI ID can support up to 8 LUNs. Most SCSI host adapter treats each LUN like a SCSI disk. 3.7.

3.7.4 Volume Set Migration Migrating occurs when a volume set is migrating from one RAID level to another, a volume set strip size changes, or when a disk is added to a raid set. Migration status is displayed in the volume status area of the RaidSet Hierarchy screen when one RAID level to another, a Volume set strip size changes or when a disk is added to a raid set.
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. NOTE: The Volume Set state must be Normal in order to perform Check Volume Set.
NOTE: When the 2 options are not selected, it will only check for errors. It is recommended to perform Check Volume Set with the 2 options unselected at first.
