Outline of Final Research Achievements

High reliability and availability are required for all services, not just mission critical services. The purpose of this research is to realize a resilient storage infrastructure that utilizes relatively new memory devices such as non-volatile DIMMs (NVDIMMs). Managing the journaling area on the NVDIMM reduces the data journaling overhead that was traditionally not practical from a performance point of view, and it is also expensive to do frequent synchronous writes to maintain file consistency. It became possible to obtain performance. In particular, it is effective for workloads that require high data integrity.
