Understanding Virtual Disk Parameters
This section describes the Virtual Disk Parameters that you can set when you use the Guided Configuration or Manual Configuration modes of the Configuration Wizard. You should change these parameters only if you have a specific reason for doing so. It is usually best to leave them at their default settings.
•Stripe Size: A stripe size of 64 Kbytes is supported.
•Disk Cache Policy: Select a cache setting for this disk: Unchanged, Enabled, or Disabled.
•Init State:
–No Initialization: The new configuration is not initialized and the existing data on the disks is not overwritten.
–Fast Initialization: MegaRAID Storage Manager software quickly writes zeroes to the first and last 8 Mbyte regions of the new virtual disk.
–Full Initialization: A complete initialization is done on the new configuration. This may take a long time if the disks are large.
