HP0-J73 · Question #299

Which statement describes a key benefit of HP 3PAR Thin Provisioning in Exchange environments?

The correct answer is D. It helps cut storage capacity requirements by 50% or more. HP 3PAR Thin Provisioning allocates physical storage only as data is actually written, which routinely cuts required storage capacity by 50% or more in Exchange environments where databases are significantly under-utilized.

Why each option

HP 3PAR Thin Provisioning allocates physical storage only as data is actually written, which routinely cuts required storage capacity by 50% or more in Exchange environments where databases are significantly under-utilized.

AIt makes deduplication more efficient because it uses a smaller block size

Thin Provisioning operates at the LUN allocation layer and has no effect on deduplication block size or the efficiency of the deduplication process.

BIt enables multi-node global deduplication and reduces time o restore

Multi-node global deduplication and faster restore times are features of HP StoreOnce deduplication technology, not HP 3PAR Thin Provisioning.

CIt automatically migrates the busiest data to the lowest performing storage and those with low

Automatically migrating active data to appropriate storage tiers is the function of HP 3PAR Adaptive Optimization (automated tiering), which is a separate feature from Thin Provisioning.

DIt helps cut storage capacity requirements by 50% or moreCorrect

Thin Provisioning presents Exchange mailbox databases with a large virtual volume size while consuming only the physical blocks actually written with live data. Exchange environments typically have substantial amounts of white space and deleted-item overhead, so on-demand physical allocation regularly results in 50% or greater reduction in actual storage consumed versus thick-provisioned volumes of the same size.
