QUESTION 52
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 53
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.

QUESTION 55
A company is experiencing performance problems on a third-party storage system with a large VMware environment. The company plans to migrate to an HP 3PAR StoreServ 7000.
Which benefit will the company realize from this migration?
A. ability to handle demand spikes
B. automated operating system deployment
C. support for VMware VAAI
D. built-in virtual machine management
Answer: C
Explanation:
HP 3PAR Application Software Suite for VMware The HP 3PAR Application Software Suite for VMware provides everything you need to make your VMware environment more agile and efficient-including Recovery Manager for VMware, Host Explorer for VMware, VASA support, and three essential plug-ins: the VMware Site Replication Manager (SRM) Adapter, the 3PAR VAAI plug-in, and the 3PAR management plug-in for VMware View. Application Software Suite for VMware uses system-based licensing.

QUESTION 56
A customer is planning to implement an HP StoreVirtual 4330FC Storage System
Which type of cable do they need to connect the storage system to the fabric?
A. SC Fibre Channel
B. LC Fibre Channel
C. iSCSI
D. SAS
Answer: D
Explanation:
Note:
* To prevent losing access to data during any maintenance operation on components of the SAS fabric, including the SAS switches, SAS cables, and I/O modules on the disk enclosure, first power down the storage blades using the procedures to shut down the management group in the HP StoreVirtual Storage Online Help or the HP StoreVirtual Storage User Guide.
QUESTION 57
A customer uses HP 3PAK System Reporter and Adaptive Optimization with an HP 3PAR StoreServ 10000 Storage System that runs HP 3PAR OS 3.1.1. The customer is planning to upgrade the storage system to HP 3PAR OS 3.1.2. The customer needs to use System Reporter and Adaptive Optimization on the storage system after the upgrade.
Which complications will the customer encounter after performing the upgrade? (Select two)
A. System Reporter backups must be reconfigured
B. System Reporter data does not migrate
C. Adaptive Optimization is disabled
D. System Reporter databases become corrupt
E. Adaptive Optimization must be reconfigured.
Answer: BC
Explanation:
B: Recreation of the AO configuration on the nodes is a manual process. There is no automated means of transferring AO configurations from System Reporter onto the HP 3PAR OS 3.1.2 system.
C: AO behavior continues unchanged for HP 3PAR OS 3.1.1 and earlier. For HP 3PAR OS 3.1.2 systems, Adaptive Optimization behaves as follows:
* AO configurations for HP 3PAR OS systems are allowed insofar as they are not deleted following an upgrade from HP 3PAR OS 3.1.1. However, these AO configurations are not executed by regionmover and are marked as inactive.
* Following an upgrade from HP 3PAR OS 3.1.1, AO configurations remain and can be used by administrators as a reference to recreate the AO configurations on the nodes.
