This courselet explores how to improve storage performance in Linux using Logical Volume Manager (LVM) and RAM-based caching. Learners will configure logical volumes to manage block devices flexibly and set up a caching layer to accelerate disk I/O. They will then use sysbench to benchmark performance with and without caching, measuring metrics such as throughput, latency, and transactions per second. Through hands-on exercises, learners will gain practical skills in storage configuration, performance tuning, and interpreting real-world benchmarking results.
