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 IBM LTFS Library Edition using LTO-5orTS1140 tape drives in the library

B.
Implement SAN Volume Controller with LTFS enabled, allowing IBM LTO drives to act as
vdisks

C.
Implement IBM LTFS Single Drive Edition on all IBM-supplied LTO-4 or LTO-5 drives in the
library

D.
Implement ProtecTIER with LTFS, allowing the management of tape and VTL disk under a
single controller
