Tuning the performance of virtual disks

Tuning the performance of virtual disks

You can tune these parameters in the Virtual Disk Manager:

Cluster size: Cluster size affects the performance of a virtual disk. This effect is also dependent on the average size of I/O operations. Cluster sizes can be changed by reconfiguration, but the length must remain a multiple of the new cluster size. See ``Distribution of I/O''.

Load balancing: If the I/O count is unbalanced, you can add additional disk pieces, move data or change the cluster size to balance the I/O across the array. Using the I/O statistics reported through the Examine Performance item of the Disk menu, you can track the level of activity of different drives used by a virtual disk.
