The TS4500 tape library offers high-density (HD), drive-capable and storage-only frame models that are designed to greatly increase storage capacity without increasing frame size or required floor space. The top rack, 3584 Model TR1, provides an extra 10U of rack space on any frame in a library without requiring more floor space. References: https://www.ibm.com/support/knowledgecenter/en/STQRQ9/com.ibm.storage.ts4500.doc/ts4500_library_structure.html

IBM Spectrum Protect, formerly Tivoli Storage Manager family, provides backup, snapshot, archive, recovery, space management, bare machine recovery and disaster recovery capabilities. Incorrect Answers:A: IBM Spectrum Control Standard and Advanced Editions are integrated data and storage management software solutions that provides monitoring, automation and analytics for multiple storage systems. B: IBM Spectrum Archive Single Drive Edition features IBM Linear Tape, not disk-based, File System.D: IBM Spectrum Control Base Edition is a centralized cloud integration system that consolidates a range of IBM storage provisioning, virtualization, cloud, automation, and monitoring solutions through a unified server platform. References: https://www.ibm.com/us-en/marketplace/data-protection-and-recovery

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

How the encryption key server processes encryption keys In system-managed and library-managed tape encryption, unencrypted data (clear text) is sent to the tape drive (TS1150 Tape Drive, TS1140 Tape Drive, TS1130 Tape Drive or TS1120 Tape Drive), and converted to ciphertext using a symmetric 256-bit AES Data Key (DK) generated by the encryption key server. The ciphertext is then written to tape. The encryption key server uses a single, unique Data Key for each Enterprise Tape Cartridge. This Data Key is also encrypted, or wrapped, by the encryption key server using the public key from an asymmetric Key Encrypting Key (KEK) pair. This process creates an Externally Encrypted Data Key (EEDK). The EEDK is written to the cartridge memory and to three additional places on the tape media in the cartridge. The tape cartridge now holds both the encrypted data and the means to decrypt it for anyone holding the private part of the KEK pair. The DK may also be wrapped a second time using the public key of another party to create an additional EEDK. Both EEDKs can be stored on the tape cartridge. In this way, the tape cartridge can be shipped to a business partner holding the corresponding private key. That private key would allow the DK to be unwrapped and the tape decrypted by the business partner. References: https://www.ibm.com/support/knowledgecenter/en/STFS69_3.3.0/ts7740_encryption_keys.html

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

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
