In the VSP Midrange family, which module provides power to the Cache Flash Memory (CFM) and to the cache in case of a power outage?

• APower Supply Module

• D

Explanation

Backup Module (C) serves as the emergency power source in the VSP Midrange family, specifically designed to supply power to the Cache Flash Memory (CFM) and cache during a power outage - its sole purpose is fault tolerance for data protection during unexpected failures.

Why the distractors are wrong:

• A. Power Supply Module - provides primary AC-to-DC power conversion under normal operation; it doesn't have a backup/failover role for cache protection.
• B. Power Module - a generic term not specific to this function in the VSP architecture; this is a distractor that sounds plausible but doesn't map to the dedicated backup role.
• D. Cache Module - stores data in cache memory but does not supply power; it's the recipient of power, not the source.

Memory tip: Think "Backup = Battery backup" - the Backup Module is the emergency lifeline that keeps cache data safe when the lights go out, much like a UPS keeps your PC alive during an outage. If you see "power outage + cache protection," the answer is always the Backup Module.
