OceanProtect system level reliability includes: (Multiple-choice)

Question

Options

• AWear leveling and anti wear leveling
• BActive-active controller
• CRAID-TP
• DSync and async remote replication

• A
  19% (11)
• B
  81% (46)

Explanation

OceanProtect's system-level reliability covers architectural and data protection mechanisms that ensure availability and recoverability across the storage system as a whole. Active-active controllers (B) eliminate single points of failure by having both controllers process I/O simultaneously, so the system keeps running if one controller fails. RAID-TP (C) is a triple-parity RAID scheme that tolerates up to three simultaneous drive failures, far exceeding the protection of traditional RAID-5 or RAID-6. Sync and async remote replication (D) are disaster recovery mechanisms that mirror data to a remote site-synchronously for zero RPO, or asynchronously for lower bandwidth cost-ensuring business continuity after a site-level failure.

Option A is wrong on two counts: wear leveling is a flash media lifespan management technique (component-level), not a system-level reliability feature, and "anti wear leveling" is not a real storage concept-it's a nonsense distractor designed to sound plausible alongside a real term.

Memory tip: Think "System = Structure + Strategy." B (active-active) is structural redundancy, C (RAID-TP) is structural data protection, and D (replication) is the disaster recovery strategy. Wear leveling belongs to media longevity, not system reliability-it keeps drives healthy, not the system available.
