Ceph入门到精通-高功性能文件系统hpfs

This is a metadata server for a distributed file system that supports concurrent operations from multiple metadata instances. Its primary use case is scenarios with extremely large metadata volumes (with tens of millions to billions of files) and high-frequency metadata operations, where it demonstrates significant effectiveness. In our tests, using 8 machines with 32 cores each as clients, running 128 threads per machine for operations like open, write 4096 bytes, and close, hpfs-srvr utilizes 2 machines with 64 cores each, and the Ceph cluster consists of 6 servers each with 8 NVMe disks. Our IOPS are tens of times higher than those of a similarly configured CephFS. Theoretically, with an increase in hpfs-srvr instances, IOPS linearly scale up, as long as the backend RADOS can support this level of IOPS capability. We are now offering core functionalities
