Configuration > Creating a Spanned Disk Array

Creating a Spanned Disk Array

Spanning allows you to configure multiple arrays as a single virtual disk. Spanned arrays provide additional levels of data redundancy and storage capacity. MegaRAID Storage Manager supports three types of spanned arrays:

Follow these steps to create a spanned disk array (see Manual Configuration for more information). The example given here is for RAID 10, but the steps are the same for RAID 00 or RAID 50.

  1. Open the Configuration Wizard and select the Manual Configuration option.
  2. On the first Manual Configuration screen, select disks for two or more RAID 1 arrays (2 disks per array).
  3. Select hot spares for the arrays, if desired, and click Next when you have defined all the arrays you want.
  4. On the next screen (Virtual Disk Creation), select two or more of the new arrays from the Arrays with Free Space menu. You can select up to eight arrays for the spanned array.
  5. Select RAID 10 from the drop-down RAID Level menu (or RAID 00 or RAID 50 for the other types of spanned arrays).
  6. Change the virtual disk properties as needed, and then click Accept to accept the spanned array. The newly defined virtual disk appears on the screen.
  7. Click Next to continue, and click Finish in the last screen to complete the process.
