QUESTION 61
A customer is migrating data to a storage array with 7 TB of storage capacity. They need 6 TB to be presented on this array for an existing database requirement.
Which storage virtualization technology should this customer use to optimize the utilization of their available storage?
A. block-level data compression
B. primary storage deduplication
C. virtual replication
D. thin provisioning
Answer: D
Explanation:
Thin provisioning promises higher capacity utilization rates and is a feature in most storage systems. But buyer beware--not all thin technologies are created equal. HP Converged Storage offers the most comprehensive and advanced set of thin technologies in the industry. With HP, your data center can be lean and efficient.
With HP thin technologies, you can:
* Start thin, so you can get the most from every dollar and disk. Easily utilize 80% or more of your purchased capacity with thin provisioning, which, unlike competitive offerings, does not require pre-planning or space reservations.
* Cut storage capacity needs in half--guaranteed.1
Changes IT refresh cycles by providing simple data mobility across clusters or generations of storage systems without downtime.
* Expect high efficiency and high performance--not tradeoffs. With HP 3PAR StoreServ Storage, thin technologies are embedded in hardware, so you can run all of your workloads in a thin state and still have high performance.
* Reclaim nearly 100% of unused space.
HP's thin reclamation technology continually hunts down wasted space in fine-grained, 16k increments and returns that capacity to the system for use by other applications.

QUESTION 63
A customer is planning to migrate data from an HP EVA4400 to an HP 3PAR StoreServ 7000 Storage System. What should the customer use to migrate the data?
A. Recovery Manager
B. Online Import
C. Peer Motion
D. Remote Copy
Answer: B
Explanation:
EVA to 3PAR Online Import manages the migration of data from a source EVA storage system to a destination 3PAR storage system. Using EVA to 3PAR Online Import, you can migrate EVA virtual disks and host configuration information to a 3PAR destination storage system without changing host configurations or interrupting data access.
Incorrect:
Not C: Peer Motion can be used for HP 3PAR not for HP EVA:
HP 3PAR Peer Motion Software is the first non-disruptive, do-it-yourself data migration tool for enterprise block storage. With Peer Motion, HP 3PAR Storage System customers can load balance I/O workloads across systems at will, perform technology refresh seamlessly, cost- optimize asset lifecycle management, and lower technology refresh capital expenditure.
Unlike traditional block migration approaches, Peer Motion enables customers to migrate storage volumes between any HP 3PAR Storage Systems online, non-disruptively, and without complex planning or dependency on extra tools. Peer Motion leverages HP 3PAR Thin Built InTM technology to power the simple and rapid inline conversion of inefficient, "fat" volumes on source arrays to more efficient, higher-utilization "thin" volumes on the destination 3PAR Storage System.
Peer Motion Manager is an add-on application that orchestrates all stages of the data migration lifecycle to ensure data migration is simple and fool-proof.
QUESTION 64
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 65
A customer is planning to migrate a database to a new site. They need to create an extended SAN in a single fabric namespace by using a dedicated link over a distance of 200 km.
Which network protocol should they use to achieve this goal?
A. FCIP
B. iFC
C. FCoE
D. iSCSI
Answer: A
Explanation:
FCIP connects Fibre Channel fabrics over IP-based networks to form a unified SAN in a single
fabric. FCIP relies on IP-based network services to provide connectivity between fabrics over LANs, MANs, or WANs.
Note:
HP SAN extension technologies include:
* FCIP
(greater than 10 km to 20,000 km)
* FC-ATM
* FC-SONET
* WDM
(greater than 35 km to 100?00 km)
* Fibre Channel using long-wave transceivers
(10 km?5 km)
QUESTION 66
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.

QUESTION 69
A storage administrator needs to perform a gradual migration of large backup volumes and jobs to a remote D2D system over time. Because this data is being replicated for the first time, the administrator needs to populate the target device with all the relevant hash codes.
Which method should the administrator use to achieve this goal?
A. using co-location
B. using removable media
C. seeding data over the WAN link
D. setting initializer to migration
Answer: C
Explanation:
* prior to being able to replicate only unique data between source and target D2D, we must first ensure that each site has the same hash codes or "bulk data" loaded on it ?this can be thought of as the reference data against which future backups are compared to see if the hash codes exist already on either source or target. The process of getting the same bulk data or reference data loaded on the D2D source and D2D target is known as "seeding".
* Seeding is generally is a one-time operation which must take place before steady-state, low bandwidth replication can commence. Seeding can take place in a number of ways:
/ Over the WAN link ?although this can take some time for large volumes of data / Using co-location where two devices are physically in the same location and can use a GbE replication link for seeding. After seeding is complete, one unit is physically shipped to its permanent destination.
/ Using a form of removable media (physical tape or portable USB disks) to "ship data" between sites.
