QUESTION 5
A large enterprise is experiencing exponential growth of data but shrinking backup windows. They need to design, plan, and integrate a comprehensive disaster recovery solution for all their data centers. Part of their disaster recovery solution must include data migration to a remote site.
How does the HP StoreOnce 6200 Backup System respond to this customer’s requirements?
A. by supporting more than 32 concurrent data streams to a single VTL or NAS share device
B. by supporting a single fabric with dual switches where the drives are presented to a single port for
no single point of failure
C. by requiring a smaller volume of seeding data to be sent over a WAN link than previous StoreOnce
D2D models
D. by providing built-in low-bandwidth replication for cost-effective copies of data offsite
Answer: D
Explanation:
Challenges in Enterprise Data Protection Requirements for a modern Enterprise Data Protection solution have many drivers:-
* Exponential growth of data Shrinking backup windows
* The need to design, plan and integrate a comprehensive Disaster Recovery capability
* The need for backup devices to be more available than ever before
The HP B6200 StoreOnce Backup System responds to all these requirements by providing:
* Deduplication to drive more efficient storage of data
* Large device scalability to ensure every backup has access to devices and, so, reduce queuing time
* (D) In-built low bandwidth replication for cost-effective copies of data offsite as part of a Disaster Recovery plan
* HP Autonomic failover (with appropriate ISV software) to allow backups to continue, even if a node in an HP B6200 StoreOnce Backup System fails.
* High scalability in terms of capacity, performance and replication to ensure the system grows as your business grows.

QUESTION 7
A company with a first-generation deduplication appliance is migrating to an HP StoreOnce 6200 Backup System. After migration, what will be the size of the deduplication block?
A. 4 kb
B. 8 kb
C. 16 kb
D. 32 kb
Answer: A
Explanation:
Deduplication Optimization
HP created a highly-optimized deduplication approach that introduces time- and space-saving techniques. With the goal of eliminating the maximum amount of redundancy in its data inspection, while also maintaining a small index to deliver the fastest performance, the company focused on two components of its deduplication approach: an average variable chunk size of 4K, and a sparse index.
HP’s Adaptive Micro-Chunking uses variable-length data segments or chunks. The backup stream is broken down into approximately 4K variable-length segments that are examined for redundancy versus previously stored information. Smaller segments means there are more chunks and index comparisons, which also means a higher potential to locate and eliminate redundancy (and produce higher reduction ratios). Comparative solutions use block sizes that range from 8K to 32K. The tradeoff with small chunk sizes is a greater number of index look-ups–which could mean slower deduplication performance. However, HP Labs developed HP Predictive Acceleration technology to maintain performance and reduce RAM requirements. By using a subset of key values stored in memory, StoreOnce determines a small number of sequences already stored on disk that are similar to any given input sequence–what HP refers to as sparse indexing. Then each input sequence is only deduplicated against those few sequences. This minimizes disk IO and uses less disk and little memory, creating more efficiency and enabling faster ingest and, importantly, restoration of data. HP’s approach accelerates reads/writes, and delivers rapid ingest rates of up to 28 TB/hour. Predictive Acceleration has enabled HP to require up to 50% less RAM than comparable solutions.
QUESTION 8
A customer plans to migrate data from an HP EVA4400 to an HP 3PAR StoreServ 7000. The customer has VMware vSphere 5 that uses the HP EVA4400.
How can the customer migrate the VMware storage without disruption?
A. by configuring load-balancing between storage systems
B. by verifying the EVA is running a supported firmware
C. by upgrading the VMware vSphere version
D. by configuring multipathing between storage systems
Answer: A
Explanation:
The concept of a storage profile, introduced in vSphere 5, extends the base VASA functionality. These profiles are used in conjunction with the capabilities of the LUN to determine which LUNs meet the needs of a VM. vSphere 5 can use this information to migrate virtual machines between LUNs for load balancing using Storage Distributed Resource Scheduler (DRS) while maintaining the storage performance and availability needs (RAID level, etc.) of the virtual machine. These profiles also allow vSphere to make placement decisions automatically based on the needs of the VM and the available datastores, further reducing the administration impact.
