A customer is impressed by the cost savings shown in the IBM proposal to consolidate their tape infrastructure replacing Oracle 9840 and 9940 tape drives with TS1140. However they are concerned about replacing their 9840 drives as they have a specific workload which requires fast access to the data. What is the best response to this concern?

A. the 9840 does not provide fast access so there is no issue

B. the TS1140 has a faster data rate than the 9840 so it will provide faster access to first byte of data

C. instead of a specific drive type for the workload, using the IBM Economy Data Cartridge provides the required fast access

D. the newer drive technology in the TS1140 will fail less frequently than the 9840 so overall provide faster access capability

A customer has replaced an old virtual tape subsystem with a new TS7740 and would like to compare the batch run times before and after the change. What tool is available in IBM Tape tools to do this?

A. VEHSTATS

B. IOSTATS

D. Batch Magic

A customer wants to double the capacity and throughput capability of the existing TS3510 Tape Library. The available free space in the data center is limited so 324 frames must be included in the proposal. Which fact must the technical specialist take into account in order to meet the customer requirements?

A. 324 frames do not provide the option for adding tape drives

B. 324 frames cannot be placed at either end of the tape library

C. 324 frames provide 2.5 times more cartridge slots compared to D frames

D. 324 frames offer reduced `amounts per hour' when using cartridges in tiers 0 and 1

What function does the TS7700 Sync Mode Copy enable or perform?

A. It copies the synchronized volumes between the clusters

B. It synchronizes the copies of the TS7700 databases between clusters

C. After writing the entire volume the TS7700 uses Sync Mode Copy to synchronize the data between all clusters

D. When the host application issues an explicit synchronize operation all previously written records are replicated to another cluster

A customer has TS1120 tape drives used with an inventory of 200 JA cartridges and 200 JB cartridges, all currently written by the TS112O drives at the highest density format.
