Figure 15 Storage management process example
Physical storage elements
The lowest level of storage management occurs at the physical drive level. Minimally, choosing the
best disk carving strategy includes the following policies:
•
Analyze current corporate and departmental structure.
•
Analyze the current file server structure and environment.
•
Plan properly to ensure the best configuration and use of storage.
•
Determine the desired priority of fault tolerance, performance, and storage capacity.
•
Use the determined priority of system characteristics to determine the optimal striping policy
and RAID level.
