HP0-J73 · Question #15

Which HP strategy supports a storage customer during migrations to prevent downtime?

The correct answer is A. federated storage. HP's federated storage strategy uses technologies like Peer Motion to interconnect storage arrays and enable transparent, non-disruptive data migration so hosts remain online throughout the process.

Why each option

HP's federated storage strategy uses technologies like Peer Motion to interconnect storage arrays and enable transparent, non-disruptive data migration so hosts remain online throughout the process.

Afederated storageCorrect

HP's federated storage strategy treats multiple storage arrays as a unified pool, using tools such as Peer Motion and Virtual Storage Appliance to move data between systems while maintaining continuous host access. This strategy specifically addresses the risk of downtime during migrations by abstracting the underlying array transitions from the connected hosts. It is HP's architectural answer to non-disruptive storage transitions at the enterprise level.

Bstorage tiering

Storage tiering automatically moves data between performance tiers (SSD, SAS, NL-SAS) based on access frequency and has no role in preventing downtime during array-to-array migrations.

CReduplication

Reduplication is not a recognized HP storage strategy - deduplication eliminates redundant data blocks to save capacity but does not address migration downtime.

DLUN-binding

LUN-binding restricts LUN visibility to specific host initiator ports for security and zoning purposes and is unrelated to migration planning or preventing downtime.
