Quick Start

If you want to try how CURVE works, you can deploy an all-in-one environment. If you want to try it in production environment, you can deploy multi-machine cluster. The depoly document has Chinese version only. The English version is on the way.


So far, we have implemented a high performance block storage system, which supports snapshot, clone and recovery, and it can be attached to QEMU virtual machine or physical machine (by curve-nbd). CURVE has been served as an elastic block storage service inside NetEase for a certain time, during which high performance and reliability have shown.
