A network-based file sharing environment is composed of multiple file servers or NAS devices. It might be required to move the files from one device to another due to reasons such as cost or performance. File-level virtualization, implemented in NAS or the file server environment, provides a simple, non-disruptive file-mobility solution. File-level virtualization enables the movement of files across NAS devices, even if the files are being accessed by the clients.
File-level virtualization eliminates the dependencies between the data accessed at the file level and the location where the files are physically stored. It creates a logical pool of storage, enabling users to use a logical path rather than a physical path, to access files. A global namespace is used to map the logical path of a file to the physical path names. Leave a Reply Cancel reply.

Greatly simplified, the three look something like this: Of course, those aren't the only way things can be done.

In the block level world, you need to create a volume, deploy an OS, and then attach to the created volume; in the file level world, the storage device handles the files and folders on the device. This also means that, in many cases, the file level storage device or NAS needs to handle user access control and permissions assignment. Some devices will integrate into existing authentication and security systems. On the backup front, file level storage devices sometimes require special handling since they might run non-standard operating systems, so keep that in mind if you decide to go the file level route.
With the caveat that you may need to take some steps with regard to authentication, permissions, and backup, file level-only devices are usually easier to set up than block level devices. In many cases, the process can be as simple as walking through a short configuration tool and moving forward.
If you're looking for storage that screams -- that is, if you need high levels of storage performance -- be very careful with the file level option. In most cases, if you need high levels of performance, you should look at the block level options. Block level devices are generally configurable for capacity and performance. Although file-level devices do have a performance component, capacity is usually the bigger consideration. The block and file worlds are converging. Some new storage devices include both block and file-level capabilities.
