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 twelve (12) 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.

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 15 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.
64bit LBA: the max. size 512TB, for Unix or Linux. Due to LSI53C1030T does not support 16byte CDB for 64bit LBA, vendor specific 12byte CDB is used for 64bit LBA support. The system may detect up 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. For Windows: 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.
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.
