Can I connect (passtrough) that card (Nvidia Quadro K4200) to a many VM (Windows)? Maybe something like RemoteFX oin HyperV?

Yes, but it is only 25% of host performace.

The results are pretty the same. Timing buffered disk reads: 446 MB in 3.01 seconds = 148.30 MB/sec

Now I have 25 osd. There must be some problem. I can get 800MB/s on the same server without ceph inside VM. On ceph I can get only 100MB/s inside VM? WTF? root@prox-a1:~# rados bench -p ceph_storage 60 write --no-cleanup Total time run: 61.044912 Total writes made: 750 Write size: 4194304...

Yes, I have 10Gbit LAN. I made 15 osd and the speed is really the same 5MB/s. What is wrong?

OK, thanks for your answear. Can I set an extra node to cluster without ceph storage only for quorum?

I have 4 node setup - 4 identical servers. Setup is ok, everything looks fine. I am trying to simulate a node failure before i will start to using that cluster. When I shutdown 1 node (3 nodes are connected together): Cluster, HA, CEPH - everything is fine. But the problem is when I...
