Demo Questions
Question 1
An IBM DS8886 customer wishes to replicate data from the primary data center to a new secondary data center 310 miles (500km) away while maintaining a low recovery point objective.
Which offering should the technical specialist recommend?
- SnapMirror
- Metro Mirror
- Global Mirror
- FlashCopy
Correct answer: C
Explanation:
Global Mirror is a long-distance remote copy function across two sites using asynchronous technology. Global Mirror processing is designed to provide support for virtually unlimited distance between the local and remote sites, with the distance typically limited only by the capabilities of the network and the channel extension technology. Incorrect Answers:B: Metro Mirror provides real-time mirroring of logical volumes between two DS8000 storage units that can be located up to 300 km from each other.References: https://www.ibm.com/support/knowledgecenter/en/HW213_7.1.0/com.ibm.storage.ssic.help.doc/f2c_copysgintro_1xiohq.html Global Mirror is a long-distance remote copy function across two sites using asynchronous technology.

Question 2
A customer has existing fiber attached storage that has reached the end of life. The customer wants a scalable solution that is easy to manage and integrates with VMware. The customer prefers an IBM A9000R based solution, but is concerned about migrating the virtual machines and ESX boot volumes.
Which explanation addresses the customer’s concern?
- Use VMware Storage vMotion to migrate virtual machines and boot volumes.
- IBM A9000R has both a vCenter and VAAI plug in.
- Use IBM Spectrum Control to virtualize and move existing storage to the new IBM A9000R.
- IBM A9000R has a built in capability to copy the existing data.
Correct answer: A
Explanation:
VMware VMotion: Allows the live migration of running VMs from one physical server to another, one data store to another, or both. This migration has zero downtime, continuous service availability, and complete transaction integrity.References: http://www.redbooks.ibm.com/redpapers/pdfs/redp5425.pdfUsing the IBM Spectrum Accelerate Family in VMware Environments, page 15 VMware VMotion: Allows the live migration of running VMs from one physical server to another, one data store to another, or both.

Question 3
A customer is purchasing an IBM 3952 Tape Frame for an IBM TS3500 Tape Library.
In which resource can you find the customer’s detailed worksheets to complete the installation?
- IBM 3952 Tape System SAPR Guide
- IBM TS3500 Tape Library with System z Attachment Guide

Correct answer: A
Question 4
IBM has proposed Easy Tier as part of a storage solution to address less-active data on flash in a storage environment.
How does Easy Tier Address this problem?
- It moves data to the appropriate tier.
- It moves data to cloud storage
- It creates space-efficient flash copies.
- It archives data to tape.
Correct answer: A
Explanation:
The system includes IBM Easy Tier, which is a function that responds to the presence of drives in a storage pool that also contains hard disk drives (HDDs). The system automatically and nondisruptively moves frequently accessed data from HDD MDisks to flash storage MDisks, thus placing such data in a faster tier of storage. The system supports these tiers:* Tier 0 flash Tier 0 flash tier exists when the pool contains high-cost, high performance flash drives. * Tier 1 flash Tier 1 flash tier exists when the pool contains tier 1 flash drives. Tier 1 flash drives are lower-cost flash drives, typically with larger capacities, but slightly lower performance and write endurance characteristics. * Enterprise tier Enterprise tier exists when the pool contains enterprise-class MDisks, which are disk drives that are optimized for performance. * Nearline tier Nearline tier exists when the pool contains nearline-class MDisks, which are disk drives that are optimized for capacity.

Question 5
A customer is considering a storage consolidation project. The IBM technical specialist wants to show how the IBM solution will be more cost-effective than the competitors.
Which tool should the technical specialist use?
- IBM Compresimator
- IBM TCOnow!
- IBM Disk Magic
- IBM Spectrum Scale Discovery Checklist
Correct answer: B
Explanation:
TCOnow! for Disk is designed for storage architects to compare the initial costs and TCO of the most popular arrays from EMC, IBM, HPE, NetApp and Hitachi. Incorrect Answers:A: Comprestimator is a command line host-based utility that can be used to estimate an expected compression rate for block devices.References: http://cioview.com/disk.html TCOnow! for Disk is designed for storage architects to compare the initial costs and TCO of the most popular arrays from EMC, IBM, HPE, NetApp and Hitachi.

Question 7
What should a technical specialist request to provide latency analysis for an Oracle DB system and help predict performance impact of IBM Flash Systems?
- DB Trace report
- nmon analyzer report
- Perfrep report
- AWR report
Correct answer: D
Explanation:
IBM FlashSystem offers customers the ability to speed up databases to rates that may not be possible even by over provisioning the fastest spinning disk arrays. You can use native Oracle Database tools to determine the effects that flash storage can have on Oracle Database environments. Oracle utilities—Statspack and now Automatic Workload Repository (AWR) reports —provide database administrators with detailed information concerning a snapshot of database execution time. This snapshot provides statistics on wait events, latches, storage input and output volumes, and timings as well as various views of memory and SQL activities.

Question 8
A customer has a requirement to add high availability to all systems in the data center. It has an IBM TS4500 tape Library in use.
What must be added to the library to meet the high availability requirement?
- Additional convenience I/O stations
- Redundant Library Managers
- Dual accessors
- Dual grippers
Correct answer: C
Explanation:
When an optional second accessor is installed, the TS4500 tape library features high availability (HA) which enhances the library performance.
