Benefits¶
Hwameistor cloud-native local storage¶
IO localization
100% local throughput, no network overhead, Pod starts on the replica node when the node fails, and uses the replica data volume for local IO read and write.
High Performance, High Availability
- 100% IO localization to achieve high-performance local throughput
- 2 copies of data volume redundant backup to ensure high availability of data
Linear expansion
- Independent node unit, minimum 1 node, unlimited number of extensions
- Separation of control plane and data plane, node expansion, does not affect business application data I/O
Small CPU and memory overhead
IO localization, the same IO read and write, CPU is stable, no large fluctuations, memory resource overhead is small
Production can be operated and maintained
- Support node, disk, data volume group (VG) dimension migration
- Support operation and maintenance behaviors such as disk replacement
