XOCE - not working on 10Gb speed
-
Okay so everything is correctly set then
During a backup, check the host and XO VM stats, you will see on which network the traffic is flowing
-
yes it is going to the right eth ( eth6 ) of the server, as you can see in photo below,
but not on the max speed. Eth in photo is form 0 to 5 not 1 to 6. And green one is connection to NAS
-
The main reason why I configured the backup server to be connected to the NAS, is because in case the main server no longer works I can switch to the backup server and in the back TrueNAScore to make a copy to the VM that exists on the backup server to the another NAS.
-
From a quick look, your backup speed is roughly average. You will never have 10G speed for VM export/backup.
-
can you tell me why, what is the technical reason ?
It is a single VM that exists on two servers, main and copy. Nothing else -
What kind of backup mode are you using?
-
on Saturday I make a full backup ( VM has 2.5TB in 3 vHDD ) the rest, which does not affect me as a transfer, is delta (continuous replication )
-
that was why I detected the problem with continuous replication
it is an Continuous Replication backup with Full backup interval set to reset on Saturday -
Try to connect in HTTP to your hosts and see if it's better.

I don't understand how to connect to HTTP, on Settings/Server is ssh
What I tried as a test was to make a VM with windows on server 2 and to map an hdd from server 1 ( iSCSI mode ) and an hdd from NAS ( iSCSI mode ), the average speed being 270 Mb real speed. VM had both network cards set to the server's 10Gbps network cards.XOCE is on ubuntu 20.04
The total transfer on windows is 3 to 4 hours, in XOCE it is 17 to 20 hours. Same value as size of files

- Not it's not SSH. XO is talking to the XAPI directly on port 443 by default. If you use
http://<IP ADDRESS>it will use plain HTTP instead of HTTPS. - VM export code is completely unrelated to the storage speed. It's not the same data path at all. VM export is using a VHD program in the dom0 that will expose it in HTTP(S), also computing the delta on the fly.
- There's no "network card speed" in the VM, because there's no emulation, only hypercalls (if you have the PV drivers installed).
- Not it's not SSH. XO is talking to the XAPI directly on port 443 by default. If you use

I understand, now I have a new track to test the connection.
I thought that everything was done on ssh/scp.
XOCE is set to work on https.Thank you

Just change HTTP in the Settings/server to connect to your pools with
http://<IP>that's it
