Correct Answer: D

The IBM Storage Tier Advisor Tool is a Windows console application that analyzes heat data files produced by Easy Tier and produces a graphical display of the amount of "hot" data per volume and predictions of how additional Solid State Drive (SSD) capacity, Enterprise Drive and Nearline Drive could benefit performance for the system and by storage pool.

Correct Answer: D

Remote-copy port groups are unique to IP partnerships, and are the local and remote IP addresses accessible to each other through an IP partnership. A remote-copy port groupmust contain at least one IP address in the local system and one IP address in the remote system. You must configure ports and assign to them a remote-copy port group number before establishing the IP partnership.

A remote-copy port group is designatedby a number between 0 and 2 inclusive that identifies a set of IP addresses. These port groups are defined as follows:

Group 0 ?These ports are not configured for remote copy (supports iSCSI host attachment by default) Group 1 ?Ports that belong to remote-copy port group 1 Group 2 ?Ports that belong to remote-copy port group 2 The system will select one pair of IP addresses within port groups 1 and 2, one address on each system, and will open a remote copy connection between them.

Correct Answer: C

Storwize V7000 is designed for all-flash or hybrid storage, while Storwize V7000 Unified isdesigned for block and file needs.

When you choose Storwize V7000 Unified and Storwize V7000, you gain the most advanced storage technologies to unlock the business value of your stored data, including virtualization and IBM Real-time Compression.

Correct Answer: A

Sizing the systems for replication

*

Metro Mirror has the least impact to the amount of IO a system can handle, as it has the lowest overhead.

*

Regular Global Mirror further lowers the maximum throughput of the system, and the increase in host write response time depends on the quantity of IO being replicated via Global Mirror. The main cause of increased write response time is spikes of host write IO that there's insufficient partnership bandwidth to replicate instantly, but we have seen cases where the increased overhead of the Global Mirror processing has made a workload unusable.

Correct Answer: B

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 createup to two local copies of a volume.

Correct Answer: A

The IBM System Storage Interoperation Center (SSIC) is used to check for hardware and software compatibility.

Correct Answer: A

Store up to five times as much active data in the same physical space with IBM Real-time Compression. It is supported by the three StorwizeV5000 hybrid models: IBM Storwize V5030, IBM Storwize V5020 and IBM Storwize V5010.

Correct Answer: D

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.

Correct Answer: D

Before V7.4, the disk space of a storage pool was provided from MDisks, so the capacity of a storage pool depended on the MDisks' capacity. Creating or splitting a storage pool is not possible and a user cannot freely make astorage pool with a particular capacity they want. A child pool is a new logical object that is created from a physical storage pool and provides most of the functions that Pools have (for example, volume creation), but the user can specify the capacity ofthe child pool at creation.

A child pool is an object similar to a storage pool, and can be used interchangeably with a storage pool. It supports volume copy and migration.

Correct Answer: B

Using the NFS protocol, you can transfer files between computers running Windows and other non-Windows operating systems, suchas Linux or UNIX.

Note:Shares and exports can be managed through the GUI or CLI by Storwize V7000 Unified administrative users that have a user role definition that is authorized to perform share and export management functions.

A share or export results from making a disk space accessible through the protocols specified during its creation. HTTP, SCP, FTP, CIFS and NFS shares and exports can be created, provided that the corresponding protocol is enabled for the system. Shares and exports can only be created for data that is stored in the GPFS file system of the Storwize V7000 Unified system. Non-GPFS file system content cannot be shared or exported.
