Open-CAS/open-cas-linux ★ 300 103 APPLICATION

Open CAS Linux is a production-grade block-layer cache acceleration solution for Linux. It consists of a kernel module (`cas_cache`) implementing caching logic on top of the OCF (Open Cache Framework), a block device module (`cas_bd`), and a user-space management CLI (`casadm`). The system accelerates block I/O by caching hot data on fast storage (e.g., NVMe/Optane) while using slower backing storage, with support for multiple cache modes, cleaning policies, I/O classes, and statistics reporting. Management is performed via ioctls through `/dev/cas_ctrl` and netlink-based communication, with a comprehensive CLI (`casadm`) for cache/core lifecycle operations and statistics output in text, CSV, and raw CSV formats.
