  • Page 33: Sequential Data Striping

    Sequential data striping The Virtual Storage Platform’s enhanced RAID 5+ implementation attempts to keep write data in cache until parity can be generated without referencing old parity or data. This capability to write entire data stripes, which is usually achieved only in sequential processing environments, minimizes the write penalty incurred by standard RAID 5 implementations.

  • Page 34: Cu Images, Lvis, And Logical Units

    Figure 2-5 LDEV Striping Across 4 RAID 5 (7D+1P) Array Groups All data drives and device emulation types are supported for LDEV striping. LDEV striping can be used in combination with all Virtual Storage Platform data management functions. CU images, LVIs, and logical units This section provides information about control unit images, logical volume images, and logical units.

  • Page 35: Logical Units

    The LVI configuration of the Virtual Storage Platform storage system depends on the RAID implementation and physical data drive capacities. The LDEVs are accessed using a combination of logical disk controller number (00-01), CU number (00-FE), and device number (00-FF). All control unit images can support an installed LVI range of 00 to FF.
