Frequently asked questions-NAS FAQNAS applications <<previous|next>> :What about server virtualization and NAS integration?
When do you think a higher level of integration with different storage protocols will happen?
But there is real value when these protocols work together. I'm not talking about having a storage controller that supports a SAN [storage area network] and NAS [network attached storage], I'm talking about file-level awareness, understanding different file attributes, being able to act on the data (aka NAS) but then moving data using SAN protocols. If you think about it, that's the best of both worlds that combines intelligence and performance. This enables the platform to run any application in any environment without worrying about the latency of 'intelligence.'
We can potentially refer to this integration of SAN and NAS as unified storage, though this often means a single controller that can host a variety of separate protocols -- combining NAS, SAN and DAS [direct attached storage] support using iSCSI and Fibre Channel through CIFS and NFS. The 'unification' that I'm talking about is even deeper, actually allowing NAS and SAN protocols to interoperate, allowing file-level intelligence across a block-based infrastructure.
