When an XIV mirror coupling is first activated, all actual data on the source is either copied to the destination (normal initialization) or verified to be on the destination, and only changed data is copied (offline initialization). This process is referred to as initialization. References: https://www.redbooks.ibm.com/redbooks/pdfs/sg247759.pdf, page 83

The Technical Delivery Assessment (TDA) pre-installation checklist and worksheets document provides several worksheets that the customer must complete for each XIV system. References: https://www.ibm.com/support/knowledgecenter/en/STJTAG/com.ibm.help.xivgen3.doc/Gen3/PG/xiv_pln3overview.html

You can create an IBM HyperSwap topology system configuration where each I/O group in the system is physically on a different site. When used with active-active relationships to create HyperSwap volumes, these configurations can be used to maintain access to data on the system when power failures or site-wide outages occur. References: https://www.ibm.com/support/knowledgecenter/en/STVLF4_7.7.1/spectrum.virtualize.771.doc/svc_hyperswap_configuration.html

IBM FlashSystem A9000 is a highly parallel, all-flash storage solution for cloud-scale businesses:Harness the performance of highly parallel architecture and IBM FlashCore technology in one innovative system Optimize storage economics with pattern removal, deduplication, and compression Incorrect Answers:B: IBM FlashSystem(R) A9000R is a grid-scale, all-flash storage platform.References: https://www-01.ibm.com/common/ssi/rep_ca/7/872/ENUSAG16-0087/ENUSAG16-0087.PDF

IBM Virtual Storage Center is a storage virtualization platform and a storage management solution for cloud-based and software-defined storage. Virtual Storage Center enables organizations to monitor, automate and analyze storage. Incorrect Answers:B: IBM FlashSystem 900 all-flash storage arrays accelerate applications in mission-critical environments.D: Use IBM Spectrum Accelerate to build a flexible, cost-effective cloud environment: deploy on any x86 server.References: http://www-03.ibm.com/software/products/en/ibm-virtual-storage-center

IBM FlashSystem 900 is designed to accelerate the applications that drive business – like those using an Oracle Database. IBM FlashSystem 900 can scale usable capacity from as low as 2 TB to as much as 57 TB in a single system. FlashSystem 900 delivers Tier 0 top application performance with up to 1.1 million 100% random read IOPS and 600,000 100% random write IOPS. References: https://www.ibm.com/us-en/marketplace/flash-storage

Capacity Magic calculates the effective storage capacity of your current and future IBM Disk Subsystems through an easy-to-use graphical dialog. This tool is available to IBM Business Partners. Incorrect Answers:B: The Comprestimator utility uses advanced mathematical and statistical algorithms to perform the sampling and analysis process in a very short and efficient way. The utility also displays its accuracy level by showing the maximum error range of the results achieved based on the formulas it uses. The utility runs on a host that has access to the devices that will be analyzed, and performs only read operations so it has no effect whatsoever on the data stored on the device. C: Disk Magic provides you with a thorough understanding of your current Disk Subsystem performance and enables you to make better purchase and configuration decisions. D: The IBM Storage Tier Advisor Tool predicts whether the addition of Solid State Drive (SSD), Enterprise Drive and Nearline Drive capacity in conjunction with the Easy Tier function. References: https://www.codeweavers.com/compatibility/crossover/ibm-capacity-magic

With Spectrum Scale multiple Spectrum Protect instances use the same storage Capacity and performance management is seamless within a global name space Scalability is seamless and transparent File system replication is integrated with Spectrum Scale for different platforms Central administration of TSM storage     Note: Multiple Spectrum Protect (TSM) instances store DB and storage pools in a Spectrum Scale file system (GPFS)Spectrum Scale provides global name space for all Spectrum Protect instances Instances share all file system resources Spectrum Protect instances run on cluster nodes accessing the file system and disk directly Spectrum Scale file systems balances the workload and capacity for all TSM instances on disk Provides standardized, scalable and easy to use storage infrastructure for the multiple instances Incorrect Answers:A: IBM Spectrum Scale HDFS transparency offers a set of interfaces that allows applications to use HDFS Client to access IBM Spectrum Scale through HDFS RPC requests. References: https://www-03.ibm.com/support/techdocs/atsmastr.nsf/5cb5ed706d254a8186256c71006d2e0a/3264fd1e3716c13586257f460072493d/$FILE/SpectrumProtect_on_Spectrum%20Scale_Intro_v6.3.pdf

The TS7700 is a member of the TS line of products and builds upon previous implementations of tape storage virtualization. For example, the TS1155 Tape drive is not compatible with IBM TS7700 or Enterprise Tape Control Unit environments. References: http://www.redbooks.ibm.com/redbooks/pdfs/sg245946.pdf, IBM Tape Library Guide for Open Systems (August 2017), page 127

IBM invented the z Systems I/O architecture. Systems, SAN and DS8880 are jointly developed.
