The Future of Storage Network Technologies

Storage is a serious issue in today’s IT world. Companies depend on information storage systems. It is important that data is available at the right time to any person who needs access to it from any location. This leads to storage-centric architecture which is different from the previous processor-centric architecture. Data in various formats like texts, images, audio and video are used in applications and it is valuable and must be stored securely. Network storage becomes important to store large repositories of data. A network based smart storage system is required and the key factors for deciding the storage solution are availability, scalability, capacity, efficient utilization, flexibility, accessibility, protection and performance. This paper discusses the primary configurations of storage network - SAN, NAS and DAS and the problems related to SAN. It focuses on the recent developments – NVMeoF mainly and the next generation of storage network like SDS, RDMA.
