接今年三月告别单盘组建TrueNAS SCALE终极家用OpenZFS File Server, 先看完第一篇再继续, 否则你应该不知道在说什么
硬件上新购入一块PM9A3 3.84TB 2.5" U.2, 将Special/Metadata Vdev从原本的3-Way Mirror变成了2*2-Way Mirror然后Stripe
Slog Vdev只保留了一块900P 280GB, 除此之外, HDD Pool无任何硬件变动

重新跑CDM测试
相比4月份时的跑分, 可以看到持续写入提升巨大, 持续读取极限也被拉高到3.5GB/s, 而随机方面则可以很明显看到Mirrored Stripe带来的写入IOPS翻倍
TrueNAS SCALE HDD 2*Z2 -> PC拷贝数个大视频文件, 竟能3.2~3.3GB/s一条直线, 比原本的2.4GB/s快出接近1GB/s!
注意这里PC客户端主磁盘已经从P5800X 1.6TB变成了小海豚D6920 7.68TB, 单任务不排除会有一丢丢瓶颈, 问题应该不大
PC -> TrueNAS SCALE HDD 2*Z2拷贝数个大视频文件, 1MiB Record Size+LZ4实时压缩速度稍慢但也达到了2.6GB/s, 之前只有1.4GB/s
非RDMA网络性能大幅提升的几个主要因素
1) 前不久SCALE的第二个主要版本v22.12.0 Bluefin发布, 进一步优化各方面性能
2) Client客户端从原来的5950X变成13900K
3) Special/Metadata Vdev从3-Way Mirror变成了2*2-Way Mirror(主要体现在CDM的4KiB写入和混合) |
