The following procedures provide the basic steps needed to create an array and get your UltraTrak100 running quickly. Before beginning, you need to decide if you will create an array using the automatic setup features or if you will create the array manually.

    UltraTrak100 TX4 and UltraTrak100 TX8 User Manual A non-fault tolerant array goes "offline" when a drive is removed or fails. Since the array is not fault tolerant, the data stored in the array is no longer accessible. If the drive was removed, then it should be replaced to restore accessibility to the array.

  • Page 21: Drive Replacement

    Reconstruction begins automatically as soon as a replacement drive becomes available to the array. However, if the replacement drive was formerly part of another array, then the previous array information must be deleted (from the replacement drive – see page 29, “Delete Array”, for more details) before reconstruction begins.

  • Page 47: Appendixa - Technology Background

    A - T PPENDIX ECHNOLOGY RAID NTRODUCTION TO RAID (Redundant Array of Independent Disks) allows multiple hard drives to be combined together to form one large logical drive or “array.” As far as the operating system is concerned, the array represents a single storage device, and treats it as such.

  • Page 48: Raid 1 - Mirroring

    UltraTrak100 TX4 and UltraTrak100 TX8 User Manual RAID 1 – M IRRORING When a disk array is mirrored, identical data is written to a pair of drives, while reads are performed in parallel. The reads are performed using elevator seek and load balancing techniques where the workload is distributed in the most efficient manner.

  • Page 49: Raid 0+1 - Striping/Mirror

    RAID 0+1 – S TRIPING Striping/mirroring combines both of the previous array types. It can increase performance by reading and writing data in parallel while protecting data with duplication. At least four drives are needed for RAID0+1 to be installed. With a four-drive disk array, drive pairs are striped together with one pair mirroring the first pair.

  • Page 50: Raid 3 - Block Striping With Parity Drive

    UltraTrak100 TX4 and UltraTrak100 TX8 User Manual RAID 3 – B LOCK RAID level 3 organizes data across the physical drives of the array, and stores parity information on to a drive dedicated to this purpose. This organization allows increased performance by accessing multiple drives simultaneously for each operation, as well as fault tolerance by providing parity data.

  • Page 51: Raid 5 - Block And Parity Striping

    RAID 5 – B LOCK AND RAID 5 is similar to RAID 3 as described above except that the parity data is rotated across the physical drives along with the block data. Having the parity data striped across all the physical drives in this manner removes the random write performance bottleneck of RAID 3.

    UltraTrak100 TX4 and UltraTrak100 TX8 User Manual JBOD (S PANNING In a Spanning array, the disk array capacity is equal to the sum of all drives, even if the drives are of different capacities. Spanning stores data onto a drive until it is completely filled then proceeds to store data on to the next drive in the array.
