Question

Options

• DActive-passive gateway

• D

Explanation

HyperMetro on OceanStor Dorado V6 is active-active because both storage arrays simultaneously serve I/O - there is no standby node sitting idle - and gateway-free because hosts connect directly to both arrays using multipathing software (e.g., UltraPath) without requiring a separate mediating gateway appliance between them. This peer-to-peer design eliminates the gateway as a single point of failure and reduces latency.

Why the distractors are wrong:

• B (Active-active gateway): HyperMetro does not require a dedicated gateway device; it uses quorum arbitration (a witness/quorum server) which is a lightweight tiebreaker, not a data-path gateway.
• C (Active-passive gateway-free): "Active-passive" implies one array is in standby - HyperMetro serves reads and writes from both sites concurrently, so passive is incorrect.
• D (Active-passive gateway): Wrong on both counts - it is neither passive nor gateway-based.

Memory tip: Think of HyperMetro as two co-equal peers shaking hands directly - no middleman (gateway-free), no sleeping partner (active-active). "Metro" = two sites, both working, no bouncer at the door.
