  • Page 19: Introduction To Raid

    RAID has gained popularity because it improves I/O performance and increases storage subsystem reliability. RAID provides data security through fault tolerance and redundant data storage. The MegaRAID Express 500 management software configures and monitors RAID disk arrays. Although disk drive capabilities have improved drastically, actual performance has been Improved I/O improved only three to four times in the last decade.

  • Page 21: Megaraid Express 500 - Host-Based Raid Solution

    A host-based RAID product provides the best performance. MegaRAID Express 500 is part of the file server, so it can transmit data directly across the computer’s buses at data transfer speeds up to 132 MB/s.

  • Page 22: Raid Overview

    A RAID system can be implemented in a number of different versions (or RAID Levels). The standard RAID levels are 0, 1, 3, and 5. MegaRAID Express 500 supports all standard RAID levels and RAID levels 10, 30, and 50, special RAID versions supported by MegaRAID Express 500.

  • Page 23: Disk Rebuild

    A rebuild rate of 100 percent means the system is totally dedicated to rebuilding the failed drive. The MegaRAID Express 500 rebuild rate can be configured between 0% and 100%. At 0%, the rebuild is only done if the system is not doing anything else. At 100%, the rebuild has a higher priority than any other system activity.

  • Page 24: Hot Spares

    Express 500 RAID Management software allows you to specify physical drives as hot spares. When a hot spare is needed, the MegaRAID Express 500 controller assigns the hot spare that has a capacity closest to and at least as great as that of the failed drive to take the place of the failed drive.

  • Page 25: Parity

    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.

  • Page 26: Disk Striping

    For example, a four-disk array with disk striping has a stripe width of four. Stripe Size The stripe size is the length of the interleaved data segments that MegaRAID Express 500 writes across multiple drives. MegaRAID Express 500 supports stripe sizes of 2 KB, 4 KB, 8 KB, 16 KB, 32 KB, 64 KB, or 128 KB.

  • Page 27: Disk Mirroring

    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.

  • Page 31: Raid Levels

    There are six official RAID levels (RAID 0 through RAID 5). MegaRAID Express 500 supports RAID levels 0, 1, 3, and 5. LSI Logic has designed three additional RAID levels (10, 30, and 50) that provide additional benefits. The RAID levels that MegaRAID...

  • Page 33: Raid 0

    RAID set. RAID 0 offers high bandwidth. By breaking up a large file into smaller blocks, MegaRAID Express 500 can use several drives to read or write the file faster. RAID 0 involves no parity calculations to complicate the write operation. This makes RAID 0 ideal for applications that require high bandwidth but do not require fault tolerance.

  • Page 34: Raid 1

    RAID 1 In RAID 1, MegaRAID Express 500 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.

  • Page 35: Raid 3

    RAID 3 RAID 3 provides disk striping and complete data redundancy though a dedicated parity drive. The stripe size must be 64 KB if RAID 3 is used. RAID 3 handles data at the block level, not the byte level, so it is ideal for networks that often handle very large files, such as graphic images.
  • Page 36 Continued RAID 5 vs RAID 3 You may find that RAID 5 is preferable to RAID 3, even for applications characterized by sequential reads and writes, because MegaRAID Express 500 has very robust caching algorithms. The benefits of RAID 3 disappear if there are many small I/O operations scattered randomly and widely across the disks in the logical drive.

  • Page 37: Raid 5

    Use RAID 5 for transaction processing applications because each drive can read and write independently. If a drive fails, MegaRAID Express 500 uses the parity drive to recreate all missing information. Use also for office automation and online customer service that requires fault tolerance.

  • Page 39: Raid 30

    RAID 30 RAID 30 is a combination of RAID 0 and RAID 3. RAID 30 provides high data transfer speeds and high data reliability. RAID 30 is best implemented on two RAID 3 disk arrays with data striped across both disk arrays. RAID 30 breaks up data into smaller blocks, and then stripes the blocks of data to each RAID 3 raid set.

  • Page 70: Step 6 Set Termination

    For a disk array, set SCSI bus termination so that removing or adding a SCSI device does not disturb termination. An easy way to do this is to connect the MegaRAID Express 500 card to one end of the SCSI cable and to connect an external terminator module at the other end of the cable.

  • Page 71: Scsi Termination

    You complete the SCSI bus by setting termination at both ends. You can let MegaRAID Express 500 automatically provide SCSI termination at one end of the SCSI bus. You can terminate the other end of the SCSI bus by attaching an external SCSI terminator module to the end of the cable or by attaching a SCSI device that internally terminates the SCSI bus at the end of the SCSI channel.

    Glossary Array A grouping or array of disk drives combines the storage space on the disk drives into a single segment of contiguous storage space. MegaRAID can group disk drives on one or more SCSI channels into an array. A hot spare drive does not participate in an array.
