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.
• Include the appropriate number of physical drives in the arrays to create logical storage elements
of desired sizes.
