    Chapter 1: Introduction Promise Array Management (PAM) is a utility application designed specifically for monitoring and managing Promise Technology RAID products, such as the FastTrak SX4000 series and S150 SX4 RAID Controller cards. Promise includes BIOS-based RAID management utilities with each of its products. PAM, however, runs over a local area network and makes possible RAID monitoring and management from any computer on the network and even over Internet.
  • Page 6: How They Work Together

    Promise Array Management How They Work Together The Promise Array Management (PAM) utility provides and easy way to set up, monitor, modify and repair your RAID. PAM works with the Promise FastTrak SX4000 series and S150 SX4 Controller card. PAM watches the RAID and when significant events happen, or it discovers a problem, the Message Agent sends a warning to the Message Server.

  • Page 68: Synchronize An Array

    Synchronize an Array Promise uses the term synchronization to mean an automated process of checking and correcting data and parity. Unlike a Rebuild, Synchronization is a maintenance operation. Synchronization applies to RAIDs 1, 0+1 and 5. It takes place when an array is first created and then, optionally, on a regularly scheduled basis to maintain content integrity.
  • Page 69 On Demand Synchronization In addition to schedule Synchronization, you can direct FastTrak to begin the Synchronization process immediately. To access this feature: Figure 59.

  • Page 71: Expand / Convert An Array

    Expand / Convert an Array Expansion and Conversion are two different operations but they often work together. Expansion means adding disk drives to an existing array. Conversion means changing an existing array from one RAID level to another. FastTrak S150 SX4 and SX4000 support this feature, however SX4000 lite does not support it.

  • Page 78: Array Critical

    Array Critical When a disk drive fails on a fault-tolerant array (RAID 1, 0+1 and 5) for any reason, the Array goes Critical. The array can still read and write data but fault tolerance has been lost. An Array Critical quickly to call your attention to the condition.
  • Page 79 In the example above, there are three disk drives attached to the FastTrak controller and all three are assigned to a RAID 5 array. The three disk drives appear under the Controller but only two appear under the Array. The disk drive on Channel 2 does not appear under Array. This is the suspect drive.
  • Page 80: Rebuild An Array

    Promise Array Management Rebuild an Array To Rebuild to restore redundancy to a RAID 1, 0+1 or 5 after one of its drives has failed. Unlike Synchronization, a Rebuild is a repair operation. When a drive fails for any reason, the Array goes Critical. An Array Critical icon displays in Tree View and the RAID alarm beeps quickly to call your attention to the condition.

  • Page 85: Array Offline

    Array Offline When a disk drive fails on a non-fault-tolerant array (RAID 0) for any reason, the Array goes Offline. The array cannot read or write data. All of the data on the array will be lost unless the failed drive is restored to operation. A fault-tolerant array (RAID 1, 0+1 and 5) will go Offline if two disk drives fail.

  • Page 87: Appendix A: Raid Concepts

    Appendix A: RAID Concepts RAID is an acronym that stands for Redundant Array of Independent Disks. It is divided into different numbered Levels. The numbers of these Levels do not mean that one Level is higher or better than another. Each Level has its own advantages and shortcomings.
  • Page 88: Striping (Raid 0)

    Striping (RAID 0) Reads and writes sectors of data interleaved between multiple drives. When any disk member fails, it affects the entire array. Performance is better than a single drive since the workload is balanced between the array members. This array type is for high performance systems. Identical drives are recommended for performance as well as data storage efficiency.
  • Page 89: Mirroring (Raid 1)

    Mirroring (RAID 1) Writes duplicate data on to a pair of drives while reads are performed in parallel. RAID 1 is fault tolerant because each drive of a mirrored pair is installed on separate controller channels. If one of the mirrored drives suffers a mechanical failure (for example, spindle failure) or does not respond, the remaining drive will continue to function.
  • Page 90: Striping / Mirroring (Raid 0+1)

    Striping / Mirroring (RAID 0+1) A combination of RAID 0 and RAID 1 arrays. It can increase performance by reading and writing data in parallel while protecting data with duplication. A minimum of four drives are required. With a four-drive disk array, two pairs of drives are striped. Each pair mirrors the data on the other pair of striped drives.
  • Page 91: About Dual Data Redundancy

    About Dual Data Redundancy One unique (though rarely occurring) feature of RAID 0+1 is dual fault tolerance. In some cases, two drives can fail simultaneously and still maintain the integrity of data. There are six combinations in which two drives can fail. FastTrak SX4000 series and S150 SX4 protect the data array in four of those cases.
  • Page 92: Block And Parity Striping (Raid 5)

    Block and Parity Striping (RAID 5) RAID 5 calculates parity in order to achieve redundancy rather than writing a second copy of the data, like RAID 1. Parity is distributed across the physical drives along with the data blocks. In each case, the parity data is stored on a different disk than its corresponding data block.
  • Page 93: Jbod - Single Drive

    JBOD - Single Drive An alternative to RAID, Just a Bunch of Disks (JBOD) capacity is equal to the sum of all drives in the group, even if the drives are of different sizes. JBOD appears in the User Interface as one or more individual drives. There are no performance or fault-tolerance features.
