Tape libraries are extremely hard to model, but accurate modeling is critical for system administrators to obtain valid performance estimates for their designs. This research introduces a discrete- event tape simulation platform that realistically models tape library behavior in a networked cloud environment, by incorporating real -world phenomena and effects. The platform addresses several challenges, including precise estimation of data access latency, rates of robot exchange, data collocation, deduplication/compression ratio, and attainment of durability goals through replication or erasure coding. Using the proposed simulator, one can compare the single enterprise configuration with multiple commodity library configurations, making it a useful tool for system administrators and reliability engineers. This makes the simulator a valuable tool for system administrators and reliability engineers, enabling them to acquire practical and dependable performance estimates for their enduring, cost-efficient cold data storage architecture designs.eninfo:eu-repo/semantics/closedAccessFault toleranceSimulatorsTape librariesDistributed systemsCloud storageErasure codingHpc storageArticle10.1016/j.simpat.2024.1029472-s2.0-85192165814
