HP Storage & Backup Solutions 2 — Questions and Answers
Question 1: Which HP storage technology uses Non-Volatile Memory Express (NVMe) over Fabrics to extend NVMe's low-latency benefits across a storage network?
- HP StoreOnce VSA
- HP Nimble Storage dHCI
- HP Primera with NVMe-oF (Correct answer)
- HP StoreEver LTO
Correct answer: HP Primera with NVMe-oF
HP Primera supports NVMe-oF, enabling sub-millisecond latency across shared storage fabrics rather than just direct-attached NVMe.
Question 2: In HP StoreOnce, what does the term 'Catalyst' refer to?
- A hardware acceleration chip for deduplication
- A backup protocol that performs deduplication at the source before data is sent (Correct answer)
- A cloud gateway service for offloading cold data
- A RAID controller technology for StoreOnce appliances
Correct answer: A backup protocol that performs deduplication at the source before data is sent
HP StoreOnce Catalyst is a backup protocol that moves deduplication processing to the backup client, reducing network bandwidth usage.
Question 3: An organization needs a backup appliance that can replicate deduplicated data directly to AWS S3. Which HP solution natively supports this capability?
- HP StoreOnce with Cloud Bank Storage (Correct answer)
- HP StoreEver MSL with LTO-9
- HP Nimble Storage replication
- HP 3PAR Remote Copy
Correct answer: HP StoreOnce with Cloud Bank Storage
HP StoreOnce Cloud Bank Storage enables seamless replication of deduplicated backup data to AWS S3 without re-hydrating it.
Question 4: What is the primary advantage of HP Nimble Storage's Adaptive Flash technology compared to a pure all-flash array for mixed workloads?
- Lower cost per GB by tiering cold data to high-capacity HDDs while keeping hot data on flash (Correct answer)
- Faster sequential read speeds for backup restoration
- Elimination of the need for RAID protection
- Native support for tape library integration
Correct answer: Lower cost per GB by tiering cold data to high-capacity HDDs while keeping hot data on flash
Nimble Adaptive Flash uses a hybrid architecture where HDDs store cold data cheaply and flash handles hot random I/O, reducing cost while maintaining performance.
Question 5: Which HP Primera feature automatically moves data between storage tiers without administrator intervention?
- Peer Motion
- Autonomous Data Tiering (ADT) (Correct answer)
- Remote Copy
- Express Protect
Correct answer: Autonomous Data Tiering (ADT)
HP Primera's Autonomous Data Tiering (ADT) uses AI-driven analytics to automatically promote or demote data blocks between NVMe and SAS tiers.
Question 6: When configuring an HP MSL tape library for LAN-free backup, which connectivity type eliminates the backup server as a data path bottleneck?
- iSCSI over 1GbE
- Fibre Channel direct connection between backup client and tape drive (Correct answer)
- CIFS/SMB share mounted on the backup server
- USB 3.0 attached tape drive
Correct answer: Fibre Channel direct connection between backup client and tape drive
LAN-free backup routes data directly from the client over Fibre Channel to the tape drive, bypassing the backup server's LAN interface.
Question 7: HP InfoSight for storage uses which type of analytics to predict drive failures before they occur?
- Reactive analytics that alert after a failure event
- Descriptive analytics showing historical IOPS trends
- Predictive analytics using machine learning trained on millions of sensor data points (Correct answer)
- Prescriptive analytics that automatically replace failed drives
Correct answer: Predictive analytics using machine learning trained on millions of sensor data points
HP InfoSight uses machine learning models trained on data from millions of devices to predict hardware failures days in advance.
