11.12 Disk/DASD

When moving existing workloads to other servers, the disk requirement is a known factor. In the following example, root requires 1507 megabytes of space. If this is shared between many servers, then this space is only required one time. Other volumes are more volatile, and disk space utilization of greater than 60 or 70% (such as in /domserva/notdesd at 94% space utilization) may be a risk. Thus, this data provides two items of importance in capacity planning for disk space: the information needed to transport workloads, and a value to check on a regular basis to avoid outages from disk full conditions.
