Not D: The SAN toolbox is used to provide a simple and effective way to represent the various components of a SAN configuration.

Not A: Want to reduce IT costs and management complexity for your arrays and SANs? Need to be ready for the next set of changes?

HP Command View EVA Software provides you with a powerfully simple storage management experience, automates and aggregates storage management to reduce complexity and increase productivity. Quickly and easily automate tasks

such as configuring RAID groups.

Provisioning capacity is simple, and you can dynamically expand LUNs and add drives online without downtime to quickly meet changing business needs. HP Command View EVA Software is a comprehensive software suite designed to

simplify array provisioning and management of all HP EVA family of storage array products.

You can easily create Vdisks and grow or shrink LUNs, all without downtime. Command View EVA Software allows you to replicate data with snapshots for immediate use.

And you can feel secure about your data with the industry-leading security features.

Correct Answer: B

Note:

*

In RAID 10, often referred to as RAID 1+0 (mirroring and striping), data is written in stripes across primary disks that have been mirrored to the secondary disks.

*

RAID 10: Mirroring without parity, and block-level striping

*

RAID 1+0: (a.k.a. RAID 10) mirrored sets in a striped set (minimum four drives; even number of drives) provides fault tolerance and improved performance but increases complexity.

*

By its definition, a Network RAID 10 volume consumes capacity at twice the rate of a Network RAID 0 volume.

Correct Answer: C

Tiered storage is the assignment of different categories of data to different types of storage media in order to reduce total storage cost. Categories may be based on levels of protection needed, performance requirements, frequency of use,

and other considerations. Since assigning data to particular media may be an ongoing and complex activity, some vendors provide software for automatically managing the process based on a company-defined policy.

As an example of tiered storage, tier 1 data (such as mission-critical, recently accessed, or top secret files) might be stored on expensive and high-quality media such as double-parity RAIDs (redundant arrays of independent disks). Tier 2

data (such as financial, seldom-used, or classified files) might be stored on less expensive media in conventional storage area networks (SANs). As the tier number increased, cheaper media could be used. Thus, tier 3 in a 3-tier system might

contain event-driven, rarely used, or unclassified files on recordable compact discs (CD-Rs) or tapes.

Not B:

Much like vMotion in VMware environments, storage federation goes beyond the capabilities of storage virtualization. Storage federation from HP enables the online non-disruptive movement of storage volumes between arrays in a metro

area. Unlike external storage virtualization appliances that add cost, complexity and downtime, storage federation from HP creates a persistent pool of capacity using native communication between system controllers.

Correct Answer: A

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.

Correct Answer: C

Mapping the same data type to the same device improves deduplication ratios, even if it comes from multiple media servers. Reference; HP B6200 Backup System, Recommended Configuration Guidelines
