One of key methods to increase the efficiency of computing resources utilization in supercomputer centers is to link them into a distributed network. For user jobs and data to be able to migrate in a supercomputer center network, there should be a distributed storage system providing a single file space for all centers.

The paper considers the existing methods and means of implementing distributed storage systems and analyzes their applicability to a supercomputer center network. It states the requirements to a distributed storage system for different aspects of its development and use: data and its metadata storage, user job life cycle support, and data security. Additionally, the paper defines possible options and techniques of implementing stated requirements into a distributed storage system of supercomputer center network.
