How does Easy Tier address this problem?

A. It moves data to cloud storage.

B. It creates space-efficient flash copies.

C. It moves data to the appropriate tier.

D. It archives data to tape

Answer: C

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.

A. Use of a distributed grid architecture

B. Support for multiple versions of OpenStack software

C. Built in performance monitoring of key resources

D. Capacity on Demand addition of useable storage

Answer: A

Explanation:

IBM XIV Cloud Storage for Service Providers, or client hosted cloud solutions require elastic, rapid response, and dynamic demand that is captured within XIV’s 485

TB linear scalability, and the immediate and automatic redistribution, without interruption, of added capacity. The grid design stripes data across all modules and

disks, incorporating data redundancy for consistent and predictable I/O performance that is always load balanced.

Incorrect Answers:

D: With Capacity on Demand (CoD) you effectively buy a certain amount of capacity up front but also get up to 3 more modules shipped with the machine. You can

start using this extra capacity when your business requirements demand it, at which point you will be asked by IBM to purchase it. The advantage here is that you

physically get a bigger machine up front with all the performance benefits that bestows, plus you don't have to contact IBM to start using that extra capacity.

Which IBM XIV benefit should the technical specialist highlight to the customer?

A. Fast rebuild speed

B. Distributed RAID

C. Distributed cache

D. IBM Hyper-Scale

Answer: A

Explanation:

When an IBM XIV disk fails, all disks in the system participate in the rebuild. The outcome? It takes less

time for theXIV system to restore full redundancy. For example, if a disk on a fully used 1 TB drive system

fails, XIV restores full redundancy in an average of 30 minutes or less, and without a significant

performance penalty. Traditional RAID systems might take up to a day to restore data reliability, with

performance compromised during rebuild. The fast XIV rebuild time means that your data spends less

time that is exposed to risk. In this way, the XIV system actually protects your data more than traditional

enterprise storage systems can.

C. Systems purchased with eight 2.9 TB flash modules can be expanded to twelve 2.9 TB flash modules.

D. Systems purchased with eight 1.2 TB flash modules can be expanded to twelve 2.9 TB flash modules.

Answer: C

Explanation:

FlashSystem 900 can be populated with up to 12 x 1.2 TB IBM MicroLatency modules in increments of 4,

6, 8, 10, or 12; or up to 12 x 2.9 TB or 5.7 TB IBM MicroLatency modules in increments of 6, 8, 10, or 12.

These modules of either 1.2 TB, 2.9 TB, or 5.7 TB cannot be intermixed. Capacity can be upgraded by

purchasing the AF23 (1.2 TB), AF24 (2.9 TB)) or AF25 (5.7 TB) IBM MicroLatency module feature codes

as MES upgrades. Here are the upgrade paths:

52.A customer looking for an all-flash solution is evaluating IBM products The primary concern for the customer is the rapid growth of its database environment.

Which IBM flash solution should the specialist recommend to control capacity utilization?

A. IBM XIV Gen3 with SSD

B. IBM DS8886 PFE

C. IBM FlashSystem 900

D. IBM FlashSystem A9000

Answer: C

53. A customer has an existing IBM XIV Gen3 solution with 3 TB drives and nine modules. While performance is acceptable, the customer wants to increase the

performance of small-block reads. The current nine modules are running at 60% of capacity.

Which solution should the technical specialist recommend?

A. Add the SSD caching option on five modules.

B. Add the SSD caching option on all nine modules.

C. Add IBM Spectrum Control Software with an IBM FlashSystem 900.

D. Add three mode data modules to improve performance.

Answer: A

Explanation:

SSD Caching improves small-block random read performance. SSD Caching in the XIV system can improve performance of any workload that is suffering from

high latency due to a high amount of small-block random read misses.

Consider a situation where you do not have an XIV system yet, but you want to know whether you might benefit from by extending the XIV with SSD Caching. On

most storage systems, you can inspect I/O statistics and determine whether a workload can benefit from SSD Caching. If the storage system has granular

reporting, you can take the following steps:

Sort your workload by read and write percentages.

The read portion of the workload can potentially benefit from the SSD Caching. A typical candidate workload for SSD Caching consists of 80% reads and 20%

writes.

Etc.

54.A customer has a two-frame IBM TS4500 Tape Library with 24 IBM TS1150 drives. The L frame is the left-most frame and the customer wants to add slots for 1100 cartridges. The available physical space in the data center is limited, so high density (HD) frames are needed. The customer has some existing IBM TS3500 storage frames that could be repurposed.

What does the customer need to understand about the upgrade?

A. An IBM TS3500 storage frame must be upgraded to HD2 before it can be redeployed.

B. The IBM TS3500 storage frames must be installed to the right of the L frame.

C. One IBM TS3500 storage frame may be installed and must be frame position one

D. A redeployed IBM TS3500 storage frame must be the last (right-most) frame.

Answer: B

Explanation:

Leverage flexibility that enables the library to grow from both the right and the left side of the first L frame since models can be placed in any active position.

55.A customer needs to exchange encrypted data cartridges with another company. A competitor offers a solution that encrypts the data with static keys loaded into the tape drives. IBM proposes IBM TS1150 tape drives using the built-in encryption feature.

Which competitive advantage does the IBM TS115O solution provide?

A. It stores keys in the drive that can then be exported to partners in a secure format.

B. It compresses the data before encrypting to achieve a better compression ratio.

C. It writes a unique encrypted data key on the cartridge using public/private key pairs.

D. It achieves better throughput by encrypting and compressing data at the same time

Answer: C

Explanation:

How the encryption key server processes encryption keys

In system-managed and library-managed tape encryption, unencrypted data (clear text) is sent to the tape

drive (TS1150 Tape Drive, TS1140 Tape Drive, TS1130 Tape Drive or TS1120 Tape Drive), and converted

to ciphertext using a symmetric 256-bit AES Data Key (DK) generated by the encryption key server. The

ciphertext is then written to tape. The encryption key server uses a single, unique Data Key for each

Enterprise Tape Cartridge. This Data Key is also encrypted, or wrapped, by the encryption key server

using the public key from an asymmetric Key Encrypting Key (KEK) pair. This process creates an

Externally Encrypted Data Key (EEDK). The EEDK is written to the cartridge memory and to three

additional places on the tape media in the cartridge. The tape cartridge now holds both the encrypted data

and the means to decrypt it for anyone holding the private part of the KEK pair.

The DK may also be wrapped a second time using the public key of another party to create an additional

EEDK. Both EEDKs can be stored on the tape cartridge. In this way, the tape cartridge can be shipped to

a business partner holding the corresponding private key. That private key would allow the DK to be

unwrapped and the tape decrypted by the business partner.
