Transparent cloud tiering is a licensed function that enables volume data to be copied and transferred to cloud storage. The system supports creating connections to cloud service providers to store copies of volume data in private or public cloud storage. With transparent cloud tiering, administrators can move older data to cloud storage to free up capacity on the system. Point-in-time snapshots of data can be created on the system and then copied and stored on the cloud storage. References: https://www.ibm.com/support/knowledgecenter/en/STVLF4_7.8.1/spectrum.virtualize.781.doc/svc_icoverviewtranparentcltier.html

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.

A scale-out NAS system is comprised of multiple NAS storage nodes with internal or external storage. Each NAS storage node represents the same file systems to user applications. Data is stored across all NAS storage nodes, and adding capacity can be achieved by adding more storage nodes. References: https://www-03.ibm.com/systems/storage/spectrum/scale/scale-out-nas.html

Global Mirror is a long-distance remote copy function across two sites using asynchronous technology. Global Mirror processing is designed to provide support for virtually unlimited distance between the local and remote sites, with the distance typically limited only by the capabilities of the network and the channel extension technology. Incorrect Answers:B: Metro Mirror provides real-time mirroring of logical volumes between two DS8000 storage units that can be located up to 300 km from each other.References: https://www.ibm.com/support/knowledgecenter/en/HW213_7.1.0/com.ibm.storage.ssic.help.doc/f2c_copysgintro_1xiohq.html

VMware VMotion: Allows the live migration of running VMs from one physical server to another, one data store to another, or both. This migration has zero downtime, continuous service availability, and complete transaction integrity.References: http://www.redbooks.ibm.com/redpapers/pdfs/redp5425.pdfUsing the IBM Spectrum Accelerate Family in VMware Environments, page 15

The system includes IBM Easy Tier, which is a function that responds to the presence of drives in a storage pool that also contains hard disk drives (HDDs). The system automatically and nondisruptively moves frequently accessed data from HDD MDisks to flash storage MDisks, thus placing such data in a faster tier of storage. The system supports these tiers:* Tier 0 flash Tier 0 flash tier exists when the pool contains high-cost, high performance flash drives. * Tier 1 flash Tier 1 flash tier exists when the pool contains tier 1 flash drives. Tier 1 flash drives are lower-cost flash drives, typically with larger capacities, but slightly lower performance and write endurance characteristics. * Enterprise tier Enterprise tier exists when the pool contains enterprise-class MDisks, which are disk drives that are optimized for performance. * Nearline tier Nearline tier exists when the pool contains nearline-class MDisks, which are disk drives that are optimized for capacity. References:  https://www.ibm.com/support/knowledgecenter/STVLF4_7.8.0/spectrum.virtualize.780.doc/svc_easy_tier.html

TCOnow! for Disk is designed for storage architects to compare the initial costs and TCO of the most popular arrays from EMC, IBM, HPE, NetApp and Hitachi. Incorrect Answers:A: Comprestimator is a command line host-based utility that can be used to estimate an expected compression rate for block devices.References: http://cioview.com/disk.html
