문제5

A customer builds a solution with SAN Volume Controller and an XIV system.
For best performance how many paths should be used between the SVC and the XIV system?

A. all XIV interface module FC ports should be zoned to each FC port on each SVC node

B. each SVC port should have one path to all available XIV interface modules

C. each I/O group must have one path to all available XIV interface modules

문제7

A storage administrator wishes to migrate a legacy storage controller's volumes to a SAN Volume Controller. The controller can provide SAS or iSCSI host connections only. An XIV is virtualized by the SVC and has been upgraded from six modules to nine to assist with the migration project. The additional storage is yet to be presented to the SVC.
What would be the best method to transfer the data?

A. Present volumes to the SVC using iSCSl. Mirror the volumes onto the newly-presented XIV storage.

B. Present volumes to the XIV using SAS. Migrate the volumes to XIV using the availablecapacitythen to the SV

C. Presentvolumestothe SVC using SAS. Mirrorthe volumes onto the newly-presented XIV storage.

D. Present volumes to the XIV using iSCSl. Migrate the volumes to XIV using the availablecapacitythen to the SVC.

정답: D
