Web关于ceph的iops计算仅供参考,计算结果可能会跟物理环境实测有较大偏差。 4.1 iops估算. 参考上述公式,结合测试报告,推算公式如下: iops = 硬盘iops * 硬盘数量 / 副本数量(只针对写) 随机读写: 磁盘iops = (随机读+随机写)/ 2 (按照平均值计算) Web随机读写IOPS; 读写延迟; 顺序读/写; 混合读/写IOPS; 随机读写带宽. 随机读测试表明,GlusterFS,Ceph和Portworx的读取性能比Azure本地磁盘上的主机路径好几倍。 OpenEBS和Longhorn的性能几乎是本地磁盘的两倍。原因是读取了缓存。

Node 1 has 48 GB of RAM and 10 cores ( Intel 4114 ), and Node 2 and 3 have 32 GB of RAM and 4 cores ( Intel E3-1230V6 ) Each node has an Intel Optane 900p (480GB) NVMe dedicated to Ceph.

For example, for NVMe drives, Ceph can easily utilize five or six cores on real clusters and up to about fourteen ... knotted onesie
