QUESTION 11A customer wishes to provide a VMware administrator with storage capacity to manage the volume creation. The system only has one storage pool.How should the customer configure the existing system to limit the capacity provided to the administrator?

A. Use IBM Spectrum Control Base

B. Create one large volume

C. Create another storage pool with new storage

D. Create a child pool


Explanation/Reference: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 astorage pool is not possible and a user cannot freely make a storage pool with a particular capacity they want. A child pool is a new logical object that is createdfrom a physical storage pool and provides most of the functions that Pools have (for example, volume creation), but the user can specify the capacity of the childpool 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.

QUESTION 15A customer is implementing an IBM Storwize V7000 Unified solution and will access both file and block storage. Two fibre channel adapters are included withineach controller.What is the maximum number of fibre channel connections the customer can connect to its SAN fabrics?

A. 12

B. 6


C. 4

D. 16


Explanation/Reference:With the introduction of the 2076-524 nodes, and the ability to have up to eight FC ports per node, there are several different options that are valid for attachingstorage to the Storwize V7000 Gen2 cluster.

Apply these Storwize V7000 Unified configuration details for Fibre Channel and Fibre Channel Over Ethernet (FC/FCoE Gateway, FCF) switches to ensure that youhave a valid configuration.Configuring your SAN with at least two independent switches, or networks of switches, ensures a redundant fabric with no single point of failure. If one of the twoSAN fabrics fails, the configuration is in a degraded mode, but is still valid. You should maintain separate fabrics for FCoE and FC. If you attempt to combine thesefabrics, you might risk adding additional paths to the volumes. Supported configurations allow a maximum of eight paths.

QUESTION 19How does the IBM Storwize native IP replication provide optimal utilization of the IP network?

A. It communicates with external WAN Optimization devices to achieve maximum efficiency.

B. It uses Real-time Compression of data prior to replication.

C. It uses artificial intelligence and sends multiple parallel streams.

D. It utilizes intelligent switches in the network to minimize latency.


Explanation/Reference:The native Internet Protocol (IP) replication feature enables replication between any SVC/Storwize family member running code version 7.2 or higher, using thebuilt-in networking ports of the cluster nodes. Following a recent partnership with IBM, it uses SANslide technology developed by Bridgeworks Limited ofChristchurch, UK. They specialize in products that can bridge storage protocols and accelerate data transfer over long distances.Adding this technology at each end of a wide area network (WAN) Transmission Control Protocol/Internet Protocol (TCP/IP) link significantly improves the usage ofthe link. It does this by applying patented Artificial Intelligence (AI) to hide latency normally associated with WANs.

The technology built into the SVC/Storwize code uses TCP/IP latency to its advantage.Rather than wait for the acknowledgment to come back, it sends more sets of packets across other virtual connections. The number of virtual connections iscontrolled by the AI engine.This improves WAN connection use, which results in a data transfer rate approaching full line speed.

QUESTION 29A customer is looking to replicate data to its disaster recovery location. The customer has gathered data about I/O and throughput to the storage.Which piece of information is needed to properly size the bandwidth needed between the two locations?

A. Peak write IOPS

B. Peak write MBps

C. Peak read IOPS

D. Peak read MBps


Explanation/Reference: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 beingreplicated via Global Mirror. The main cause of increased write response time is spikes of host write IO that there's insufficient partnership bandwidth to replicateinstantly, but we have seen cases where the increased overhead of the Global Mirror processing has made a workload unusable.

Explanation/Reference:Note:IBM Spectrum Virtualize includes IBM Easy Tier, a function that responds to the presence of drives in a storage pool that also contains hard disk drives (HDDs). Thesystem automatically and nondisruptively moves frequently accessed data from HDD MDisks to flash storage MDisks, thus placing such data in a faster tier ofstorage.

The system supports these tiers:* Flash tierThe flash tier exists when flash MDisks are in the pool. The flash MDisks provide greater performance than enterprise or nearline MDisks.* Enterprise tierThe enterprise tier exists when enterprise-class MDisks are in the pool.* Nearline tierThe nearline tier exists when nearline-class MDisks are used in the pool.

Note 2: The formal distinction between online, nearline, and offline storage is:* Online storage is immediately available for I/O.* Nearline storage is not immediately available, but can be made online quickly without human intervention.* Offline storage is not immediately available, and requires some human intervention to become online.

QUESTION 38A customer is complaining about poor disk performance and has updated the controller code to the 7.3 release in an attempt to resolve this concern. A review of thestorage identifies a disk pool which contains seven MDisks as the potential problem.The MDisk assignment is:Four MDisks are configured as 8-drive RAID 5Three MDisks are configured as 6-drive RAID 5

You point out that his practice may be the cause of the performance concern.Which steps should be recommended to the customer?


A. 1. Create new MDisks constructed as an 8-drive RAID 5, add them to the disk pool.2. Remove each of the 6-drive MDisks from the pool.3. Let the automatic disk pool rebalance feature in the 7.3 code rebalance in the data across the MDisks.

B. 1. Add two extra drives to each MDisk containing only sex drives.2. Use the automatic disk pool rebalance feature in the 7.3 code to rebalance the data across the MDisks.

C. 1. Create new MDisks constructed as an 8-drive RAID 5, add them to the disk pool.2. Use a script to rebalance the data across the MDisks.3. Remove each of the 6-drive MDisks from the pool.

D. 1. Add two extra drives to each MDisk containing only six drives.


2. Use a script to rebalance the data across the MDisks.


Explanation/Reference:What you have to do is create a new Disk Group (mdisk) and add to your existing Pool (mdiskgrp).

The new versions of SVC / Storwize Version 7.3 can automatically rebalance the workloads across the mdisks. If you have switched this on, this rebalance scriptshould no longer be used.

Incorrect Answers:C, D: The new versions of SVC / Storwize Version 7.3 can automatically rebalance the workloads across the mdisks. If you have switched this on, this rebalancescript should no longer be used.

Note: A managed disk (MDisk) is a logical unit of physical storage. MDisks are either arrays (RAID) from internal storage or volumes from external storage systems.MDisks are not visible to host systems.An MDisk might consist of multiple physical disks that are presented as a single logical disk to the storage area network (SAN). An MDisk always provides usableblocks of physical storage to the system even if it does not have a one-to-one correspondence with a physical disk.

QUESTION 47Which network authentication protocol is supported on the IBM Storwize V7000 Unified storage system, is used for client/server applications, and providessymmetric key cryptography?

A. Network Information Service (NIS)

B. Kerberos

C. Services for UNIX (SFU)

D. POSIX


Explanation/Reference:KerberosTo provide heterogeneous file sharing for Unix and Windows, the Storwize V7000 Unified system must support authentication methods for Unix and Windows. TheStorwize V7000 Unified system uses Windows authentication for incoming CIFS connections and Unix authentication for incoming NFS, HTTP, SFTP and SCPconnections.

Kerberos is a network authentication protocol for client/server applications that uses symmetric key cryptography.

Note: User password in clear text format is never sent over a network; the Kerberos server grants a ticket to the client for a short span of time. This ticket is usedwhile communicating with the server to obtain access to the service, such as a file server. The Windows based authentication is based on Kerberos. MIT Kerberosis a free implementation of the Kerberos protocol, which is provided by the Massachusetts Institute of Technology.
