Variables that are sometimes used to determine storage utilization

Storage utilization is a measure of how well the available data storage space in an enterprise is used. There are a number of variables that can be used to determine the storage utilization in a system. The relative priorities assigned to each variable can also affect the utilization figure.

Variables that are sometimes used to determine storage utilization include:

1. the total available storage space in the entire system (raw storage)

2. the time-averaged percentage of raw storage used

3. the percentage of raw storage used at times of peak demand

4. the available storage space in each storage volume

5. the time-averaged percentage of storage used in each volume

6. the peak-demand percentage of storage used in each volume

7. the average time required to store or retrieve a file of a given size

8. the time during peak-demand periods required to store or retrieve a file of a given size

9. the average size of files stored or retrieved

10. the ease with which data can be shared among the servers in a network

11. the microprocessor speed at each server

12. the random-access memory (RAM) capacity at each server

13. the speed (in megabits or gigabits per second) with which data is transmitted among different servers

14. the operating systems used by the servers, and

15. the nature and economic value of data handled by the business.
