Abstract
A Storage Area Network (SAN) is a dedicated high-speed network architecture designed to facilitate block-level storage access for servers. By interconnecting storage devices, such as disk arrays, with servers, SAN enables efficient and rapid data retrieval. SAN differs from traditional NAS, which operates at the file level, by providing block-level access to storage. This enables greater performance, scalability, and flexibility—especially for applications that process large volumes of data. Due to its centralized storage management capabilities and reliability, SAN is widely deployed in enterprise environments, especially for disaster recovery and large-scale data processing. This study introduces an improved SAN backup technique aimed at optimizing CPU utilization and reducing link load. This study evaluates an enhanced SAN backup framework using the OPNET 14.5 simulation tool. A dedicated Fibre Channel (FC)-based architecture was modeled and tested against a conventional Ethernet-linked SAN. Simulation results show a 37% improvement in FTP response time (from 0.022s to 0.014s) and a 4% throughput increase (from 137 to 142 bytes/sec). These findings support the system’s effectiveness in reducing congestion and enhancing backup operations in enterprise-like conditions.
