Ceph is a distributed object, block, and file storage platform

etmem, the memory vertical expansion technology, uses DRAM and high-performance storage new media to form multi-level memory storage. By grading the stored data, etmem migrates the classified cold storage data from memory to the high-performance storage medium, so as to achieve the purpose of memory capacity expansion and memory cost reduction.

damo is a user space tool for DAMON. Using this, you can monitor the data access patterns of your system or workloads and make data access-aware memory management optimizations.

The openEuler kernel is the core of the openEuler OS, serving as the foundation of system performance and stability and a bridge between processors, devices, and services.

Storprototrace (storage protocol trace) is a tracing function for IO events entering the iscsi protocol driver layer based on libbpf.
