What is a file virtualization?
File virtualization is a method of allowing access to stored information in the network. Users of the File Virtualization Network are able to access files and folders that are located on multiple servers as if they were all in the same place. This allows you to move data without disturbing the user's access to it. There are two different types of file virtualization systems: outside the band and in the band.
One of the major problems of the modern computer worldwide is how to ensure that everyone has access to all information needed to work. In order to access this information, the staff must know the name space of the information or its location on the storage device. Project data can exist on several different servers located in different buildings or even in different countries.
File virtualization is a way to access files on different servers using a single access key. The user will send a request to the globalnames. Theglobal Namespace is a virtual area created by a network of file virtualization. He knows where all the files are on each server. When the user sends a request, the global name corresponds to the user to display all information associated with this access key, regardless of which server stores the data.
This system has several advantages over traditional data storage methods. The most important for users is all related information in the same place, although half is on the server in New York and the other half is on the server in Moscow. The file virtualization also allows network administrators to move data without the user knowing that this happened. As long as global names know where the data is, the user finds it using the same access key.
There are two different types of file virtualization systems. Out-of-band systems are based on software. They create virtual proxy server, withCRE to which the data is accessible. It is an older style of virtualization and only works when all files are in the system of the same type. It has difficulty coverage of large geographical areas. Files in the Band system can only be moved if users are accessible to them.
In-Band Systems inserts a physical access point on the network between users and servers. Users send to this application field to get access to files on servers. This style of virtualization works well with heterogeneous files. This is a newer technology whose main disadvantage is that if the physical access point fails, access to the virtual network is not impossible until the box is replaced.
