Abstract: Disclosed herein are a method for automatically allocating IP addresses for a distributed storage system in a large-scale torus network and an apparatus for the method. The method for automatically allocating IP addresses includes acquiring neighboring-node information from multiple storage nodes that constitute the system; generating torus network topology for the multiple storage nodes by combining the neighboring-node information; generating IP address information through which a position of each of the multiple storage nodes in a structure corresponding to the torus network topology can be identified; and allocating IP addresses to the multiple storage nodes by delivering the IP address information to the multiple storage nodes.

Abstract: Disclosed herein is a network selecting apparatus including: a determining unit checking an operation state of a cache server in which replicated data corresponding to a data request signal are stored and determining whether the cache server is normally operated, when the data request signal is received from a client; and a selecting unit selecting a first network so that the replicated data are transmitted to input and output devices when the cache server is normally operated and selecting a second network so that original data corresponding to the data request signal are transmitted from a storage server in which the original data are stored to the input and output devices when the cache server is not normally operated.

Abstract: There are provided a system and method for providing a virtual desktop service using a cache server. A system for providing a virtual desktop service according to the invention includes a host server configured to provide a virtual desktop service to a client terminal using a virtual machine, a distributed file system configured to store data for the virtual machine, and a cache server that is provided for each host server group having at least one host server, and performs a read process or a write process of data using physically separate caches when the read process or write process of the data is requested from the virtual machine in the host server.
