Description

This seminar presents the fundamental principles necessary for setting up and administering a storage network. It addresses the key points of all phases of a SAN/NAS implementation project: collection of storage needs for company applications, choice of a supplier, definition of the architecture, migration of applications on the SAN, and finally administration. The main aspects of the course concern both technical and organizational aspects. Technological developments are evaluated from the point of view of their use by the company.
