Not accurate Question... Dell EMC ViPR Controller A software-defined storage platform that abstracts, pools, and automates a data center’s physical storage infrastructure. It delivers block and file storage services on demand through a self-service catalog. It supports data protection across geographically dispersed data centers. It provides a single control plane to manage heterogeneous storage environments, including Dell EMC and non-Dell EMC block and file storage

should be power max

PowerMax Supported Storage Type = Block, file, open systems, IBM i, and mainframe

It is PowerMax

Right answer is PowerMax

VPLEX does not support NAS (Files) , FASTvp is a data service in old VNX, XtremeIO does not support NAS, Powermax support block&file .. and it is software defined since it is unified (One question earlier asks about definition of software defined and it was unified mgmt) so correct answer should be powermax but it is confusing since you think software defined can be run on any hardware but it is not correct.

Consolidation of block and file storage using eNAS Embedded NAS (eNAS) data service extends the value of PowerMax to file storage by enabling customers to leverage vital enterprise features including flash level performance for both block and file storage, as well as simplify management, and reduce deployment costs. PowerMax, with the eNAS data service, becomes a unified block and file platform, using a multi-controller, transactional NAS solution Correct answer is A

I think the right answer is PowerMax
