Hello,
I'm setting up a Ceph storage with Proxmox 5.0 beta, based on Debian
Stretch.
It's based on 3 Dell PowerEdge R610's, bonded with 3 NIC's. (I'll get
back on this in a bit), all 3 with PERC H700 and RAID1 Kingston SSD.
Writing speeds directly on the SSD give me roughly 300MB/s (which is
still slow, as it should reach 500MB/s).
The switch they are connected to is a HP PowerConnect 2824
The issue I'm having is that when I test my storage speeds I'm only
getting 80MB/s via Ceph.
If testing directly with netperf I'm getting 112MB/s. (I followed the
following guide for testing:
https://blog.codecentric.de/en/2014/03/ceph-object-storage-fast-gets-benchmarking-ceph/)
I have setup bonding, exactly the same on all 3 nodes. All configs can
be found below.
I tried using 'mtu 9000' in the config, but then I got packet loss and
total connection loss. Unkown what's causing it but I disabled it again.
Anyone that might have a clue what I'm doing wrong/what is wrong with
the setup?
Note: Current setup will be for testing only, once everything is
succesfull we will invest in 10G NIC's.
