Question #6
An IBM i customer decided to take advantage of the performance of flash-based storage and is implementing an IBM FlashSystem V9000. The customer plans to move all data to the V9000 with native IBM i attachment.
Which connection protocol is required for this environment?
  1. A
    FC
  2. B
    FTP
  3. C
    10 Gb FCoE
  4. D
    InfiniBand

Correct Answer:
A
IBM FlashSystem V9000 can be attached to IBM i in the following ways:
* Native connection without using Virtual I/O Server (VIOS)
Native connection with SAN switches can be done with these adapters:
4 Gb Fibre Channel (FC) adapters, feature number 5774 or 5276
8 Gb FC adapters, feature number 5735 or 5273
16 Gb FC adapters, feature number EN0A or EN0B
Direct native connection without SAN switches can be done with these adapters:
4 Gb FC adapters in IBM i connected to 8 Gb adapters in IBM FlashSystem V9000
16 Gb adapters in IBM i connected to 16 Gb adapters in IBM FlashSystem V9000
* Connection with VIOS in N_Port ID Virtualization (NPIV) mode
There are rules for mapping server virtual FC adapters to the ports in VIOS when implementing IBM i in VIOS NPIV connection.
* Connection with VIOS in virtual SCSI (VSCSI) mode

Question #7
What is the minimum of connections that an IBM Storwize node canister should have to a host according to best practices?
  1. A
    4
  2. B
    1
  3. C
    2
  4. D
    6

Correct Answer:
C
The system contains a Storwize V7000 storage system. Each Storwize V7000 single processing unit is a node canister, which is also called a node. The two nodes within their canisters make an I/O group that is attached to the SAN fabric.
Each Storwize V7000 control enclosure requires two Ethernet cables to connect it to an Ethernet switch or hub. One cable connects to port 1 of the left node canister, and the other cable connects to port 1 of the right node canister. A 10/100/1000 Mb Ethernet connection is required for each cable. Both Internet Protocol
Version 4 (IPv4) and Internet Protocol Version 6 (IPv6) are supported.
Note: For increased redundancy, an optional second Ethernet connection is supported for each Storwize V7000 node canister.

Question #8
A customer has purchased an IBM Storwize solution and needs to externally virtualize a Dell EqualLogic PS6210E.
Which connection protocol is required?
  1. A
    FCoE
  2. B
    iSCSI
  3. C
    SAS
  4. D
    FCIP

Correct Answer:
B
Support for iSCSI backend storage attachment for SAN Volume Controller and the Storwize storage virtualisation family include the Dell Equallogic PS6210 storage model.

Question #9
A customer with excessive annual growth is looking at a storage refresh.
Which benefit does the IBM Storwize V7000 offer this customer?
  1. A
    It supports in-place fork-lift system upgrades.
  2. B
    It can virtualize other vendors’ storage for unlimited time and size.
  3. C
    It can scale up and scale out through clustering.
  4. D
    It can perform a software transfer when moving to the next model.

Correct Answer:
C
v6.2 Storwize V7000 offers both Scale-Up and Scale-Out possibilities for ultimate flexibility.
Control enclosures support attachment of up to nine expansion enclosures with configurations up to 360 TB physical internal storage capacities (for Storwize
V7000, up to 1.44 PB in clustered systems)
Flex System V7000 can scale up to 240 (2.5" disks) per control enclosure; 960 (2.5" disks) per clustered system.

Question #10
A company just completed an acquisition and now has FC attached storage from multiple vendors. The environments are isolated and storage administrators are unable to share resources across these environments.
Which IBM Storwize solution feature helps improve this situation?
  1. A
    Real-time Compression
  2. B
    Encryption
  3. C
    Tiered Storage Optimizer
  4. D
    External Virtualization

Correct Answer:
D
By using external virtualization, you can consolidate FC SAN-attached disk controllers from various vendors into pools of storage. In this way, the storage administrator can manage and provision storage to applications from a single user interface and use a common set of advanced functions across all of the storage systems under the control of the IBM Storwize.
