3: Identify Key Resources To Be Measured
Once the process owner is selected, one of his or her first tasks will be to identify the infrastructure resources whose utilizations or performance need to be measured. This determination is made based on current knowledge about which resources are most critical to meeting future capacity needs. In many shops, these resources will revolve around network bandwidth; the number and speed of server processors; or the number, size, or density of disk volumes comprising centralized secondary storage. Following are some other resources often identified for consideration:
- Channels
- Tape drives
- Centralized memory in servers
- Centralized printers
- Desktop processors
- Desktop disk space
- Desktop memory
