Measure - Storage Utilization
The Storage-Utilization measure reports the
proportion of storage capacity used. The measure provides an indication of whether storage resources are sufficient to store
projects and/or the anticipated volume of operational data
generated by the system. The term "storage" refers to magnetic and optical
media (e.g. disk, tapes, hard drives, CD-ROM, etc.), but
specifically excludes all types of random access memory (RAM), read only
memory (ROM), or any other forms of electronic
Applicable to all
domains. Primarily used for weapon systems
Critical for storage
