PFS存储引擎10/17/22 2 Why ●为了减少使用cpu做内存copy，减少系统调用 ●发挥某些被操作系统屏蔽的功能，例如nvme write zero ●根据阿里《When Cloud Storage Meets RDMA》的说法 ●在100Gbps网络带宽时，内存带宽成为瓶颈 ●Intel Memory Latency Checker (MLC)测试得到的CPU内存带宽是 61Gbps10/17/22 const struct iovec *iov, int iovcnt, off_t offset); ●IO vector的接口主要是为了与brpc的iobuf对接，iobuf由若干地址不连 续的block组成，一次IO提交可以提高效率。10/17/22 8 PFS+SPDK 的部分读写的实现 ●某些盘只支持4k单位读写，但是CurveBS支持512字节读写 ●可能存在部分写的并发冲突 ●引入并发的range
