陈威Curve 是高性能、高可用、高可靠的分布式存储系统 • 高性能、低延迟 • 可支撑储场景：块存储、对象存储、云原生数据库、EC等 • 当前实现了高性能块存储，对接OpenStack和 K8s 网易内部线上无故障稳定运行一年多 • 已开源 • github主页： https://opencurve.github.io/ • github代码仓库： https://github.com/opencurve/curve curve在上物理pool之上又引入逻辑pool的概念，以实现统一存储系统的需求，即在单个存储系统中多副 本PageFile支持块设备、三副本AppendFile（待开发）支持在线对象存储、AppendECFile（待开发）支持 近线对象存储可以共存。 如上所示LogicalPool与pool为多对一的关系，一个物理pool可以存放各种类型的file。当然由于curve支持 多个pool，可以选择一个logicalPool独享一个pool。 hunk可以用ChunkID+CopySetID=12个byte。 2. 减少复制组数量：如果一个数据节点存在 256K个复制组，复制组的内存资源占用将会非常恐怖；复制组之 间的通信将会非常复杂，例如复制组内Primary给Secondary定期发送心跳进行探活，在256K个复制组的情况 下，心跳的流量将会非常大；而引入CopySet的概念之后，可以以CopySet的粒度进行探活、配置变更，降低
