QUESTION NO: 1
A customer is preparing to migrate data between their data centers. They need to perform
deduplicalion at the data creation point and eliminate the need for specialized deduplication hardware in their data centers. How does HP StoreOnce Catalyst enable the customer to achieve this goal?

A. by performing source-side deduplication
B. by performing switch-side deduplication
C. by performing server-side deduplication
D. by performing target-side deduplication

Answer: A

Explanation:
By enabling source-side deduplication (Dedupe 2.0), HP has the advantage of
performing deduplication at the data creation point. Source-side deduplication eliminates the need for specialist deduplication hardware at remote and branch office sites. StoreOnce Catalyst allows customers to align backup with data protection needs, such as minimizing bandwidth utilization when moving data between sites or data centers.

QUESTION NO: 3
A customer is extending a SAN by using wavelength division multiplexing (WDM) to migrate their master database to a new data center. They need to ensure that there is adequate line speed to perform the migration in the event of a primary path failure.
What should the customer do to achieve this goal?

A. Ensure that all SAN devices use the same Fibre Channel speed.
B. Ensure that all SAN switches have the same core PID number.
C. Ensure that there are separate WDM paths for transmitting and receiving packets
D. Ensure that a secondary path with sufficient buffer-to-buffer credits is available

Answer: D

Explanation:
WDM devices extend the distance between two FICON directors. The devices are
transparent to the directors and do not count as an additional hop.
To accommodate WDM devices, you must have enough Fibre Channel BB_credits to maintain line-speed performance. WDM supports Fibre Channel speeds of 10 Gb/s, 8 Gb/s, 4 Gb/s, 2 Gb/s, and 1 Gb/s. When planning for SAN extension, BB_credits are an important consideration in WDM network configurations. Typical WDM implementations for storage replication include a primary and secondary path. You must have enough BB_credits to cover the distances for both the primary path and secondary path so that performance is not affected if the primary path fails.
