Question #21
A customer has existing SAP HANA production nodes connected to an IBM Elastic Storage Server (ESS). The customer needs to scale out additional ESS nodes to maintain the high I/O throughput requirement.
Which type of nodes should be proposed?
Which type of nodes should be proposed?
- AStorage nodes with SAS drives
- BStorage nodes with SSD drives
- CProtocol nodes with SAS drives
- DProtocol nodes with SSD drives
Correct Answer:
B
A scale-out NAS system is comprised of multiple NAS storage nodes with internal or external storage. Each NAS storage node represents the same file systems to user applications. Data is stored across all NAS storage nodes, and adding capacity can be achieved by adding more storage nodes.

Question #22
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?
Which offering should the technical specialist recommend?
- ASnapMirror
- BMetro Mirror
- CGlobal Mirror
- DFlashCopy
Correct Answer:
C
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.

Question #23
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 customers concern?
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 customers concern?
- AUse VMware Storage vMotion to migrate virtual machines and boot volumes.
- BIBM A9000R has both a vCenter and VAAI plug in.
- CUse IBM Spectrum Control to virtualize and move existing storage to the new IBM A9000R.
- DIBM A9000R has a built in capability to copy the existing data.
Correct Answer:
A
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.

Question #25
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?
How does Easy Tier Address this problem?
- AIt moves data to the appropriate tier.
- BIt moves data to cloud storage
- CIt creates space-efficient flash copies.
- DIt archives data to tape.
Correct Answer:
A
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.
