Hi, I built a CEPH 16.2.x cluster with relatively fast and modern hardware, and its performance is kind of disappointing. I would very much appreciate an advice and/or pointers :-) The hardware is 3 x Supermicro SSG-6029P nodes, each equipped with: 2 x Intel(R) Xeon(R) Gold 5220R CPUs 384 GB RAM 2 x boot drives 2 x 1.6 TB Micron 7300 MTFDHBE1T6TDG drives (DB/WAL) 2 x 6.4 TB Micron 7300 MTFDHBE6T4TDG drives (storage tier) 9 x Toshiba MG06SCA10TE 9TB HDDs, write cache off (storage tier) 2 x Intel XL710 NICs connected to a pair of 40/100GE switches
That's a lot of CPU cores and a lot of RAM for mostly spinners. Why is that? Will this be a hyperconverged solution?
Can you repeat the tests with fio with rados and rbd as ioengines on a bare metal host?
