    Overview of Virtual LVI/LUN 1.2.1 Virtual LVI/LUN Parameters The Virtual LVI/LUN (VLL) option allows you to configure variable-size volumes, which are usually smaller than normal (fixed-size) volumes. Virtual LVI/LUN improves data access performance by reducing logical device contention and host I/O queue times, particularly when several frequently accessed files are located on the same volume.
  • Page 17 Note: Virtual LVI/LUN used in conjunction with FlashAccess can achieve greater performance improvements than when either of these options is used individually. For more information on FlashAccess, see Hitachi Freedom Storage™ Lightning 9900™ V Series FlashAccess User’s Guide (MK-92RD102). A parity group is called a normal or fixed-size volume (FV) when all of its member LDEVs are fixed-size.

  • Page 18: Figure 1.3 Volume Configuration

    A normal volume consists of a certain number of fixed volumes, depending on the emulation type, and some free space. A Virtual LVI/LUN volume usually consists of at least one fixed volume (FV), customized volumes (CV or VLL volumes), and free space (see Figure 1.3).
