Introduction to RAID Introduction to RAID 9 Introduction to RAID RAID is an array of multiple independent hard disk drives that provide high performance and fault tolerance. A RAID disk subsystem improves I/O performance over a computer using only a single drive. The RAID array appears to the host computer as a single storage unit or as multiple logical units. I/O is expedited because several disks can be accessed simultaneously.
10 RAID Controller Kit-G – Host-Based RAID Solution Introduction to RAID Table 2.
RAID Overview Introduction to RAID 11 SCSI-to-SCSI External A SCSI-to-SCSI External RAID product puts the RAID intelligence inside the RAID chassis and uses a plain SCSI Host Adapter installed in the network server. The data transfer rate is limited to the bandwidth of the SCSI channel. A SCSI-to-SCSI RAID product that has two wide SCSI channels operating at speeds up to 320 MB/s must squeeze the data into a single wide SCSI (320 MB/s) channel back to the host computer.
12 RAID Overview Introduction to RAID Fault Tolerance Fault tolerance is achieved through cooling fans, power supplies, and the ability to hot swap drives. RAID Controller Kit-G provides hot swapping through the hot spare feature. A hot spare drive is an unused online available drive that RAID Controller Kit-G instantly plugs into the system when an active drive fails. After the hot spare is automatically moved into the RAID subsystem, the failed drive is automatically rebuilt.
RAID Overview Introduction to RAID 13 Disk Striping Disk striping writes data across multiple disk drives instead of just one disk drive. Disk striping involves partitioning each drive storage space into stripes that can vary in size from 2 KB to 128 KB. These stripes are interleaved in a repeated sequential manner. The combined storage space is composed of stripes from each drive. RAID Controller Kit-G supports stripe sizes of 2 KB, 4 KB, 8 KB, 16 KB, 32 KB, 64 KB, or 128 KB.
14 RAID Overview Introduction to RAID Disk Mirroring With mirroring (used in RAID 1), data written to one disk drive is simultaneously written to another disk drive. If one disk drive fails, the contents of the other disk drive can be used to run the system and reconstruct the failed drive. The primary advantage of disk mirroring is that it provides 100% data redundancy. Since the contents of the disk drive are completely written to a second drive, it does not matter if one of the drives fails.
RAID Overview Introduction to RAID 15 Disk Spanning Disk spanning allows multiple disk drives to function like one big drive. Spanning overcomes lack of disk space and simplifies storage management by combining existing resources or adding relatively inexpensive resources. For example, four 60 GB disk drives can be combined to appear to the operating system as one single 240 GB drive. Spanning alone does not provide reliability or performance enhancements.
16 RAID Overview Introduction to RAID Parity Parity generates a set of redundancy data from two or more parent data sets. The redundancy data can be used to reconstruct one of the parent data sets. Parity data does not fully duplicate the parent data sets. In RAID, this method is applied to entire drives or stripes across all disk drives in an array. Table 2.3 describes distributed parity, which is used in RAID 5. Table 2.
RAID Overview Introduction to RAID 17 Disk Rebuild You rebuild a disk drive by recreating the data that had been stored on the drive before the drive failed. Rebuilding can be done only in arrays with data redundancy such as RAID level 1, 5, 10, and 50. Standby (warm spare) rebuild is employed in a mirrored (RAID 1) system. If a disk drive fails, an identical drive is immediately available. The primary data source disk drive is the original disk drive.
18 RAID Overview Introduction to RAID Logical Drive States Table 2.4 describes the possible states for logical drives. Table 2.4 Logical Drive States State Description Optimal The drive operating condition is good. All configured drives are online. Degraded The drive operating condition is not optimal. One of the configured drives has failed or is offline. Failed The drive has failed. Offline The drive is not available to RAID Controller Kit-G. SCSI Drive States Table 2.
RAID Overview Introduction to RAID 19 Disk Array Types Table 2.6 describes the RAID disk array types. Table 2.6 Disk Array Types Type Description Software-Based The array is managed by software running in a host computer using the host CPU bandwidth. The disadvantages associated with this method are the load on the host CPU and the need for different software for each operating system.

Chapter 3 RAID Levels........................................................................
22 System Configuration Setup Setup
RAID Levels RAID Levels 23 RAID Levels RAID Controller Kit-G supports RAID levels 0, 1, 5, 10, and 50. This chapter describes the RAID levels, and factors to consider when you select a level. Table 3.
24 RAID Levels RAID Levels Table 3.2 describes the factors you need to consider when selecting a RAID level. Table 3.2 Factors for Selecting RAID Levels Level Description and Use Pros Cons Maximum Number of Physical Drives Fault Tolerant 0 Data divided in blocks and distributed sequentially (pure striping). Use for noncritical data that requires high performance. High data throughput for large files No fault tolerance. All data lost if any drive fails.
RAID Levels RAID Levels 25 RAID 0 RAID 0 provides disk striping across all drives in the RAID subsystem. RAID 0 does not provide any data redundancy, but does offer the best performance of any RAID level. RAID 0 breaks up data into smaller blocks and then writes a block to each drive in the array. The size of each block is determined by the stripe size parameter, set during the creation of the RAID set. RAID 0 offers high bandwidth.
26 RAID Levels RAID Levels RAID 1 In RAID 1, RAID Controller Kit-G duplicates all data from one drive to a second drive. RAID 1 provides complete data redundancy, but at the cost of doubling the required data storage capacity. Uses Use RAID 1 for small databases or any other environment that requires fault tolerance but small capacity. Strong Points RAID 1 provides complete data redundancy. RAID 1 is ideal for any application that requires fault tolerance and minimal capacity.
RAID Levels RAID Levels 27 RAID 5 RAID 5 includes disk striping at the byte level and parity. In RAID 5, the parity information is written to several drives. RAID 5 is best suited for networks that perform a lot of small I/O transactions simultaneously. RAID 5 addresses the bottleneck issue for random I/O operations. Since each drive contains both data and parity numerous writes can take place concurrently.
28 RAID Levels RAID Levels RAID 10 RAID 10 is a combination of RAID 0 and RAID 1. RAID 10 has mirrored drives. RAID 10 breaks up data into smaller blocks, and then stripes the blocks of data to each RAID 1 raid set. Each RAID 1 raid set then duplicates its data to its other drive. The size of each block is determined by the stripe size parameter, which is set during the creation of the RAID set.
RAID Levels RAID Levels 29 RAID 50 RAID 50 provides the features of both RAID 0 and RAID 5. RAID 50 includes both parity and disk striping across multiple drives. RAID 50 is best implemented on two RAID 5 disk arrays with data striped across both disk arrays. RAID 50 breaks up data into smaller blocks, and then stripes the blocks of data to each RAID 5 raid set.

Hardware Installation Hardware Installation 59 Hardware Installation Requirements You must have the following for hardware installation: • A RAID Controller Kit-G controller • A host computer with an available PCI expansion slot • The RAID Controller Kit-G Installation CD • The necessary SCSI cables and terminators (This depends on the number and type of SCSI devices to be attached.
60 Installation Steps Hardware Installation Table 6.1 Checklist for Installation (Continued) Check Step Action 8 Format the hard disk drives as needed. 9 Configure system drives (logical drives). 10 Initialize the logical drives. 11 Install the network operating system drivers as needed. Installation Steps RAID Controller Kit-G provides extensive customization options.
Installation Steps Hardware Installation 61 Step 1 Unpack Unpack and install the hardware in a static-free environment. The RAID Controller Kit-G controller card is packed inside an anti-static bag between two sponge sheets. Remove the controller card and inspect it for damage. If the card appears damaged, or if any item listed below is missing, contact Toshiba or your MegaRAID OEM support representative.
62 Installation Steps Hardware Installation RAID Controller Kit-G Card Layout J2 Dirty Cache LED J2 is a two-pin connector for the dirty cache LED. This can be connected to an LED on the computer enclosure. The LED will be lit when data in the cache has not yet been written to the storage device. that is used to clear the configuration data in the nonvolatile random access memory. J3 Clears EPROM J3 is a two-pin header that clears the erasable progammable read-only memory (EPROM) configuration data.
Installation Steps Hardware Installation 63 J5 SCSI Activity LED J5 is a two-pin connector that attaches to a cable that connects to the hard disk LED mounted on the computer enclosure. The LED indicates data transfers (SCSI bus activity.) Table 6.5 Pinout for J5 SCSI Activity LED Pin Description Pin Description 1 VCC through pullup 2 SCSI activity signal J6 Serial Port J6 is a 3-pin header that attaches to a serial cable. This is for test purposes only. Table 6.
64 Installation Steps Hardware Installation Step 5 Set Termination You must terminate the SCSI bus properly. Set termination at both ends of the SCSI cable. The SCSI bus is an electrical transmission line and must be terminated properly to minimize reflections and losses. For a disk array, set SCSI bus termination so that removing or adding a SCSI device does not disturb termination.
Installation Steps Hardware Installation 65 Terminating Internal SCSI Disk Arrays Set the termination so that SCSI termination and termination power are intact when any hard drive is removed from a SCSI channel, as shown below.
66 Installation Steps Hardware Installation Terminating External Disk Arrays In most array enclosures, the end of the SCSI cable has an independent SCSI terminator module that is not part of any SCSI drive.
Installation Steps Hardware Installation 67 Terminating Internal and External Disk Arrays You can use both internal and external drives with RAID Controller Kit-G.
68 Installation Steps Hardware Installation Connecting Non-Disk SCSI Devices SCSI tape drives, and CD drives must each have a unique SCSI ID regardless of the SCSI channel they are attached to. The general rule for Unix systems is: • Tape drive set to SCSI ID 2 • CD drive set to SCSI ID 5 WARNING: Since all non-disk SCSI devices are single ended, it is not advisable to attach a non-disk device to a RAID Controller Kit-G if LVD disk drives are also attached.
Installation Steps Hardware Installation 69 Step 6 Install RAID Controller Kit-G Choose a 3.3 V or 5 V PCI slot and align the RAID Controller Kit-G controller card bus connector to the slot. Press down gently, but firmly to make sure that the card is properly seated in the slot. The bottom edge of the controller card should be flush with the slot.
70 Installation Steps Hardware Installation Insert the RAID Controller Kit-G card in a PCI slot as shown below. Screw the bracket to the computer frame.
Installation Steps Hardware Installation 71 Step 7 Connect SCSI Cables Connect SCSI cables to SCSI devices. RAID Controller Kit-G provides two SCSI connectors: J1, the SCSI channel internal high-density 68-pin connector for Wide (16bit) SCSI and J7, the SCSI channel external very high-density 68-pin connector. Connect SCSI Devices When connecting SCSI devices, use the procedure in Table 6.8. Table 6.
72 Installation Steps Hardware Installation Step 8 Set Target IDs Set target identifiers (TIDs) on the SCSI devices. Each device in a specific SCSI channel must have a unique TID in that channel. Non-disk devices (CD-ROM or tapes) should have unique SCSI IDs regardless of the channel where they are connected. See the documentation for each SCSI device to set the TIDs. The RAID Controller Kit-G controller automatically occupies TID 7 in the SCSI channel.
