On which entity is a Cyclic Redundancy Check (CRC) function repformed when using the HP StoreOnce Backup System?
B. Transferred file
D. Backup job
Correct Answer: D Explanation
Cyclic redundancy check (CRC)
Cyclic redundancy checking (CRC) is an enhanced checksum function. When this option is selected, CRC
checksums are written to the media during backup. CRC checks allow you to verify the media after the
backup. Data Protector re-calculates the CRC during a restore and compares it to the CRC on the
medium. It is also used while verifying and copying the media. This option can be specified for backup,
object copy, and object consolidation operations. The default value is OFF.
Figure 49 shows the default configuration parameters for Ultrium tape drives. CRC checking was OFF.

Which crucial characteristics are true about the HP 3PAR Persistence Port feature? (Select two)
A. The host MPIO software must be reset to restarted after a failover scenario to restore the correct path balance
B. HP 3PAR Persistent Port requires additional failover zone for each node’s guest World Wide Name (WWN)
C. HP 3PAR Persistent Port will maintain connectivity during 3PAR mode upgrade or 3PAR node failure even with a single path host
D. HP 3PAR Persistent Port requires a minimum to two paths per each World Wide Name (WWN) with additional 1:1 zones
E. One a two node array, the HP 3PAR Persistence Port minimum setup requires each fabric switch to be physically connected equally to each in a node pair
Correct Answer: CE Explanation
http://www8.hp.com/h20195/v2/GetPDF.aspx%2F4AA4-4545ENW.pdf Features and benefits: With the
release of HP 3PAR OS version 3.1.2, HP has introduced new functionality called “Persistent Ports” that
supports non disruptive online software upgrades and recovery from node failures, in a manner that is
transparent to any FC fabric connected host accessing the HP 3PAR StoreServ.
The Server HBA ports may be zoned to only a single array Node’s port WWN or it may be zoned to both.
A customer wants to implement a new backup solution. The environment is predominantly Fibre Channel with Windows 2008, Linux hosts, and a number of HPUX hosts attached to a 10 GbE network. They have expressed an interest in the HP StoreOnce technology and its integration with HP Data Protector.
When designing an HP StoreOnce solution for this environment, what needs to be considered?
A. Catalyst integration is only supported on Windows and HPUX hosts.
B. Catalyst gateway are used on the HP-UX hosts.
C. Linux hosts requires Catalyst gateway
D. Fibre Channel hosts may only use VTL emulation.
Correct Answer: D Explanation
Each node has two 8Gb FC connections (used for VTL only), two 10GbE and four 1GbE Ethernet connections (used for NAS shares or Catalyst stores). Figure 4 illustrates these physical connections.

Which HP 3PAR InForm Operating System feature allows you to create point-in-time clones with independent service-level parameters?
A. Virtual Copy
B. Smart Copy
C. Remote Copy
D. Full Copy
Correct Answer: D Explanation
Explanation: http://www8.hp.com/us/en/products/storage-software/product-detail.html?oid=5044394#! tab=features Data Protection and Copy Space Reclamation Features Improve Capacity Utilization HP 3PAR RAID MP (Multi-Parity) uses Fast RAID 6 and the accelerated performance of the HP 3PAR ASIC to prevent data loss as a result of double disk failures. Performance levels are maintained within 15% of RAID 10 and with capacity overheads comparable to popular RAID 5 modes.
HP 3PAR Full Copy is an HP 3PAR Operating System Software feature that allows you to create thinaware, point-in-time clones with independent service level parameters which can be rapidly resynchronized with base volumes as needed.
The HP 3PAR Thin Copy Reclamation feature keeps your storage lean and efficient by reclaiming unused space resulting from the deletion of virtual copy snapshots associated with virtual copy and remote copy volumes.
A company is experiencing performance issues on their four node HP StoreServ 10800 configured with 256x 300 GB Fibre Channel drives. A System Reporter analysis reveals that single tier of Fibre Channel storage is under a lot of I/O pressure from an explosion of VMware servers running high I/O messaging applications used to track package routes daily in an Oracle database.
There are 40x 50GB thin provisioned volumes that make up 90% of mostly read I/O activity during regular business hours. The customer is upset and need a solution to quickly increase performance for these critical applications.
Which solution should you propose to cost-effectively resolve this issue?
A. Upgrade with 256 addition 300 GB drives and Adaptive Optimization to automatically move high I/O volume regions to a RAID 10 CPG for better I/O performance
B. Utilize Peer Motion to non-disruptively move the offending work load to an SSD optimized HP 3PAR StoreServ array.
C. Upgrade with 32x 100GB SSD drives and Adaptive Optimization configured for performance-based placement in two storage tiers.
D. Upgrade with 2 additional nodes and double host-facing Fibre Cannes ports to archive better I/O caching across all array nodes when accessing small volumes
Correct Answer: C Explanation
Explanation: Customer case study This section describes the real benefits that a customer derived from using HP 3PAR Adaptive Optimization. The customer had a system with 96 300 GB 15k rpm FC drives and 48 1 TB 7.2k rpm NL drives. The customer had 52 physical servers connected and running VMware with more than 250 VMs. The workload was mixed (development and QA, databases, file servers) and they needed more space to accommodate many more VMs that were scheduled to be moved onto the array. However, they faced a performance issue: they had difficultly managing their two tiers (FC and NL) in a way that kept the busier workloads on their FC disks. Even though the NL disks had substantially less performance capability (because there were fewer NL disks and they were much slower), they had larger overall capacity. As a result, more workloads were allocated to them and they tended to be busier while incurring long latencies. The customer considered two options: either they would purchase additional 96 FC drives, or they would purchase additional 48 NL drives and 16 SSD drives and use HP 3PAR Adaptive Optimization to migrate busy regions onto the SSD drives. They chose the latter and were pleased with the results (illustrated in Figure 7).
Before HP 3PAR Adaptive Optimization as described in the charts–and even though there are fewer NL drives –they incur greater IOPS load than the FC drives in aggregate and consequently have very poor latency (~40 ms) compared with the FC drives (~10 ms). After HP 3PAR Adaptive Optimization has executed for a little while, as shown in the charts on the right, the IOPS load for the NL drives has dropped substantially and has been transferred mostly to the SSD drives. HP 3PAR Adaptive Optimization moved ~33 percent of the IOPS workload to the SSD drives even though that involved moving only 1 percent of the space. Performance improved in two ways: the 33 percent of the IOPS that were serviced by SSD drives got very good latencies (~2 ms), and the latencies for the NL drives also improved (from ~40 ms to ~15 ms). Moreover, the investment in the 16 SSD drives permitted them to add even more NL drives in the future, because the SSD drives have both space and performance headroom remaining. http:// h20195.www2.hp.com/V2/GetPDF.aspx%2F4AA4-0867ENW.pdf
