This example illustrates how to monitor disk space on a volume when you create a LUN without using Snapshot copies.
For this example, assume that you require less than the minimum capacity based on the recommendation of creating a seven-disk volume.
For simplicity, assume the LUN requires only three GB of disk space. For a traditional volume, the volume size must be approximately three GB plus 10 percent. The recommended volume size is approximately 2*3 GB plus the rate of change of data.
