Note that with only 10 Gbps network, you will get only 1 GB/s wich is
only the 25-30% performance of a NVMe.
To profit the 100% performance of a NVMe you need at least a 40G network.

Hi,
a good start to get a feeling about expected performance, read this
great paper from Redhat:

if you want to build a small three node cluster, you should use a intel

Hello Tobias.
Check if your SSD is suitable for Ceph Journal:

If you can, add 2 OSD Sata disks per host.

Hi @ all
i have a question to ceph we plan to build our own ceph cluster in
datacenter. Can you tell me the performance statics from running ceph cluster
with the same setup?
We want to buy the follow setup:
3x Chassis with:
CPUs: 2 x Intel E5-2620v3
RAM: 64GB
NIC: 2x10GBit/s CEPH,
