Abstract: Veritas Clustered File System (VxCFS) is a high-performance, fault-tolerant shared-disk file system designed to ensure high availability and data consistency in clustered environments. As part of the Veritas InfoScale product suite, VxCFS facilitates concurrent data access across multiple nodes in a cluster while maintaining integrity and minimizing downtime. This review explores the key fault tolerance mechanisms implemented by VxCFS, including its cluster architecture, journaling system, fencing mechanism, high availability and failover processes, data replication, and distributed locking mechanisms. The system's ability to handle mission-critical workloads in diverse industries such as banking, telecom, healthcare, and government is highlighted. Despite its robust features, VxCFS presents challenges in terms of complex configuration, licensing costs, and hardware dependencies. Nevertheless, its scalability, low-latency operations, and high reliability make it a leading solution for organizations seeking fault-tolerant infrastructure to ensure continuous data access and business continuity in the face of failures.
