Hi all,
We have a proof of concept HCI cluster with Proxmox v7 and Ceph v15.
We have 3 nodes:
2x Intel Xeon 5218 Gold (16 core/32 threads per socket)
Dell PERC H330 Controller (SAS3)
4xSamsung PM1634 3.84TB SAS 12Gb SSD
Network is LACP 2x10Gbps
This cluster is used for some VDI tests, with Windows 10 VMs.
Pool has size=3/min=2 and is used for RBD (KVM/QEMU VMs)
We are seeing Ceph performance reaching about 600MiB/s read and 500MiB/s
write, and IOPS read about 6.000 and writes about 2.000 . Read/writes
are simultaneous (mixed IO), as reported by Ceph.
Is this a reasonable performance for the hardware we have? We see about
25-30% CPU used in the nodes, and ceph-osd processes spiking between
600% and 1000% (I guess it's full 6-10 threads use).
I have checked cache for the disks, but they report cache as "Not
applicable".
BIOS power profile is performance and C states are disabled.
Thanks
