Demo Questions

Question 1

A customer is planning to implement a new IBM Storwize V5030 solution and is evaluating the requirements for implementing disaster recovery with HyperSwap. 
Which HyperSwap configuration requirement needs to be part of installation?


  1. Both I/O groups and managed disks are at the same site.
  2. Configuration with standard topology with all control enclosures are at the same site.
  3. Configure volume mirror relationship with a controller from each I/O group at different sites.
  4. Each I/O group and its managed disks are at different sites.
Correct answer: D
Explanation:
HyperSwap volumes, where copies of a single volume are in different storage pools that are on different sites. The volume is cached in two I/O groups that are on different sites. These volumes can only be created on Storwize V5030 systems when the system topology is HyperSwap.     References: http://www.ibm.com/support/knowledgecenter/STHGUJ_7.7.0/com.ibm.storwize.tb5.770.doc/tbrd4_tbrd4ovr.html

Question 2

A cloud solution is being planned using the IBM Storwize family to provide storage for multiple clients on IBM Power and Intel hosts. 
Which solution provides the necessary storage for the primary site and a disaster recovery location at a data center 1500 kilometers away?


  1. Create a four node IBM Storwize V7000 cluster with one I/O Group at the primary data center and the other at the disaster recovery location. Use FlashCopy to copy the volumes from the primary I/O Group to the disaster recovery I/O Group.
  2. Create volumes on IBM Storwize V7000 storage at the primary data center and use Global Mirror to create copies on an IBM Storwize V7000 at the disaster recovery location.
  3. Create volume mirrors on IBM Storwize V7000 storage at the primary data center with virtualized external IBM Storwize V3700 storage at the disaster recovery location.
  4. Create volumes on IBM Storwize V7000 Storage at the primary data center and use Metro to create asynchronous copies on an IBM Storwize V5030 at the disaster recovery location.
Correct answer: B
Explanation:
Metro Mirror and Global Mirror are technologies that enable you to keep a real-time copy of a disk at a remote site that contains another SVC Cluster or Storwize V7000 system. Incorrect Answers A: FlashCopy is a function that allows you to create a point-in-time copy of one of your SVC disks. This might be helpful when performing backups or application testing. These copies may be cascaded upon one another, read from, written to, and even reversed.These copies are able to conserve storage, if needed, by being space-efficient copies that only record items that have changed from the originals instead of full copies. C: Volume Mirroring is a function designed to increase high availability of the storage infrastructure. It provides the ability to create up to two local copies of a volume.References: IBM System Storage SAN Volume Controller and Storwize V7000 Replication Family Services, page 22http://www.redbooks.ibm.com/redbooks/pdfs/sg247574.pdf

Question 7

What is the minimum of connections that an IBM Storwize node canister should have to a host according to best practices?


  1. 4
  2. 1
  3. 2
  4. 6
Correct answer: C
Explanation:
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.References: http://www.ibm.com/support/knowledgecenter/ST3FR7_7.7.0/com.ibm.storwize.v7000.770.doc/svc_portsandconnect_gen2.html

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. It supports in-place fork-lift system upgrades.
  2. It can virtualize other vendors’ storage for unlimited time and size.
  3. It can scale up and scale out through clustering.
  4. It can perform a software transfer when moving to the next model.
Correct answer: C
Explanation:

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. Real-time Compression
  2. Encryption
  3. Tiered Storage Optimizer
  4. External Virtualization
Correct answer: D
Explanation:
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. References: Implementing the IBM Storwize V5000 Gen2 (including the Storwize V5010, V5020, and V5030), page 51http://www.redbooks.ibm.com/redbooks/pdfs/sg248162.pdf
