An architect is considering whether to specify vSCSI or NPIV for the rootvg disks in a new

virtualized environment. Storage is to be provided by an IBM San Volume Controller (SVC) and
controlled using SDDPCM.
Which of the following is an advantage of using vSCSI technology instead of NPIV?

A.
Support for vSCSI devices is included within base AIX, removing the need to install device
drivers at the client level.

B.
Queue depths higher than 20 for rootvg disks are supported with vSCSI.

C.
vSCSI allows for client level logical volume mirroring for rootvg, providing enhanced protection.

D.
vSCSI provides active/active multi pathing, allowing I/O requests to be distributed between dual
VIOS partitions
