  • Page 198: Raid 0 - Striping

    VTrak 15200 User Manual RAID 0 – Striping When a disk logical drive is striped, the read and write blocks of data are interleaved between the sectors of multiple disk drives. Performance is increased, since the workload is balanced between drives or “members” that form the logical drive.

  • Page 199: Raid 1 - Mirroring

    Chapter 7: Technology Background RAID 1 – Mirroring When a logical drive is mirrored, identical data is written to a pair of disk 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 200: Raid 3 - Block Striping With Dedicated Parity

    VTrak 15200 User Manual RAID 3 – Block Striping with Dedicated Parity RAID level 3 organizes data across the disk drives of the logical drive, and stores parity information on to a disk drive dedicated to this purpose. This organization allows increased performance by accessing multiple disk drives simultaneously for each operation, as well as fault tolerance by providing parity data.

  • Page 201: Raid 5 - Block Striping With Distributed Parity

    Chapter 7: Technology Background RAID 5 – Block Striping with Distributed Parity RAID 5 is similar to RAID 3 as described above except that the parity data is distributed across the disk drives along with the data blocks. In each case, the parity data is stored on a different disk than its corresponding data block.

  • Page 202: Raid 10 - Mirroring / Striping

    VTrak 15200 User Manual RAID 10 – Mirroring / Striping Mirroring/Striping combines both of the RAID 0 and RAID 1 logical drive types. It can increase performance by reading and writing data in parallel while protecting data with duplication. At least four disk drives are needed for RAID 10 to be installed.

    Chapter 8: Troubleshooting Critical & Offline Logical Drives A fault-tolerant logical drive—RAID 1, 3, 5, 10 and 50—goes critical when a drive is removed or fails. Due to the fault tolerance of the logical drive, the data is still available and online. However, once the logical drive goes critical, the logical drive has lost its fault tolerance, and performance may be adversely affected.
