A customer is having major issues backing up a Microsoft SQL Server database whose data is resident on a DCS3700 They are interested in point-in-time copies and integration with Tivoli Storage Manager.
What two products should the technical specialist recommend as a solution? (Select two)

• A. Tivoli Storage Manager for Storage Area Networks
• B. DCS3700 FlashCopy/VolumeCopy
• C. DCS3700 Remote Mirroring
• D. Tivoli Storage Productivity Center for Data
• E. Tivoli Storage FlashCopy Manager

Which of the following is a feature of LTFS (Linear Tape File System)?

• A. presents a single virtual tape cartridge from multiple physical tape cartridges
• B. accelerates sequential disk access by emulating LTO-5 tape streaming
• C. provides file system access at the OS level to data stored in tape media
• D. creates a virtual tape library with de-duplication using disk storage

The exhibit shows a non-IBM tape library setup, where Fabric A, in addition to controlling tape drives 1 through 3, also controls the tape library controller. In the event of Fabric A loss, all control between host and library would be lost and all drives become inaccessible.
With an equivalent IBM library, in the event of Fabric A failure, which drives would be affected?

• A. Drives 1 through 3 would be inaccessible, but drives 4-6 would continue to function due to the redundant control path on Fabric B (all IBM libraries provide dual-path controllers as standard)
• B. All drives would be accessible due to the redundant control path on Fabric B (all IBM libraries provide dual-path controllers as standard)
• C. All drives would be inaccessible, as the only path to the controller is lost
• D. All drives would be accessible as IBM provides control paths via the tape devices meaning multiple control paths exist

A customer has an installed DS3524 and requests advice on how to add capacity to an existing logical drive. The technical specialist advises that hard drives need to be added to the array group first to provide the capacity to do the update.
What operations are performed within the DS3524 operating system to achieve the upgrade?

• A. Dynamic RAID migration
• B. Dynamic Volume Expansion only
• C. Dynamic Array Expansion only
• D. Dynamic Array Expansion and then Dynamic Volume Expansion

As part of a customer data management solution, it is necessary to store unused data on a low cost device to achieve the necessary cost benefit. While a tape library solution would provide low cost, the customer application is not capable of writing directly to tape.
What recommendation should the technical specialist make to allow the POSIX capable application to access tape devices?

• A. Implement SAN Volume Controller with LTFS enabled, allowing IBM LTO drives to act as vdisks
• B. Implement ProtecTIER with LTFS, allowing the management of tape and VTL disk under a single controller
• C. Implement IBM LTFS Library Edition using LTO-5orTS1140 tape drives in the library
• D. Implement IBM LTFS Single Drive Edition on all IBM-supplied LTO-4 or LTO-5 drives in the library
