Storage Management
Question
A customer wants to present a LUN to a server totaling 5TB. The server will initially use only 100GB. The storage administrator will upgrade the SAN as more storage is needed. Which of the following is the BEST feature to use to present storage to the server while maximizing storage flexibility?
Options
- ALUN Masking
- BLUN Snapshot
- CThin Provisioning
- DThick Provisioning
Explanation
LUN Masking enables storage administrators to control which servers can access specific LUNs, providing critical flexibility in managing secure and segmented storage presentation within a SAN environment.
Common mistakes.
- B. LUN Snapshot creates point-in-time copies of a LUN for backup and recovery purposes, not for initial storage presentation or maximizing flexibility related to storage capacity growth.
- C. Thin Provisioning optimizes physical storage utilization by allocating space on demand rather than upfront, which enhances storage efficiency and defers physical upgrades, but it does not directly relate to the flexibility of controlling access to the LUN for a server.
- D. Thick Provisioning allocates all physical storage for a LUN upfront, which reduces flexibility by consuming physical capacity immediately, regardless of actual usage.
Concept tested. SAN LUN management and access control
