TALICS^3: Tape Library Cloud Storage System Simulator

High performance computing data is surging fast into the exabyte-scale world, where tape libraries are the main platform for long-term durable data storage besides high-cost DNA. 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. The suggested simulator has the capability to compare the single enterprise configuration with multiple commodity library (RAIL) configurations, making it a useful tool for system administrators and reliability engineers. They can use the simulator to obtain practical and reliable performance estimates for their long-term, durable, and cost-effective cold data storage architecture designs.
