Which description of OceanStor Pacific HyperGeoEC is correct?

Question

Options

• AOnly one data center is active
• BCan tolerate three site failures
• CAt least 2 sites are required
• DMultiple data centers jointly store one data

• A
  3% (1)
• B
  6% (2)
• C
  81% (26)
• D
  9% (3)

Explanation

Option C is correct because HyperGeoEC (Geo Erasure Coding) is a geo-distributed storage technology that requires a minimum of two sites to function - it encodes data using erasure coding and distributes the chunks across geographically separated locations, making a second site structurally necessary.

Why the distractors are wrong:

• A is wrong because HyperGeoEC operates in an active-active model, meaning all participating sites are simultaneously active and serving I/O - not a single active site with passive standby.
• B is wrong because tolerating three site failures would require a significantly larger number of sites; standard HyperGeoEC configurations typically tolerate one site failure, not three.
• D sounds plausible but mischaracterizes the architecture - erasure coding distributes encoded shards across sites rather than having multiple centers "jointly store" a single piece of data as if it were shared simultaneously in the same way; the framing implies something closer to mirroring or RAID.

Memory tip: Think of HyperGeoEC as the minimum viable geo-redundancy feature - the "at least 2 sites" rule mirrors the basic principle that you need at least two locations to have geo-distribution at all. If you remember "geo = geographically separated = plural sites," option C follows naturally.
