A customer says his business wouldn't benefit from buying ARX because it already has block based storage virtualization in place. Is he right? Why or why not?

Block-based storage virtualization operates at the disk block level and abstracts physical LUNs, while file virtualization operates at the NAS and file level; they are distinct abstraction layers with entirely different capabilities.

The customer's block-based virtualization solution does not replicate ARX's file-level interception, metadata-aware policy engine, or ability to migrate files transparently across heterogeneous NAS systems.

Block-based storage virtualization cannot interpret file metadata, apply file-based migration policies, or manage files across NAS namespaces the way ARX's file virtualization engine does.

Both ARX and block-based storage virtualization abstract storage resources from servers, but they operate at different layers - ARX works at the file and NAS level, enabling policy-based file migration, tiering, and lifecycle management across heterogeneous NAS environments that block-level virtualization cannot address.
