Hi
I'm not sure if I'm in the right section, but I'm having a very strange situation.
I'm using a Vsphere 6.0 environment with 2Hosts, a netapp storage and Veeam backup and replication 8.0
Everything is redundantly connected with 1 GBIT Ethernet.
The Backup is configured to direct san access, so it can pull the data directly from the san, this is working fine.
Observations
When I start a backup job of a virtual machine that has "2" disks, the job runs at 50 MB/s per disk -> ergo: 100 MB/s
As soon as the smaller disk is finished, the speed drops to 20 MB/s for the remaining disk.
If I now start ANOTHER backup task, the speed immediately picks up to 50 MB/s again on that disk, the other 50 MB/s occupied by the new job. As soon as the newly started job finishes, the transfer speed drops again to 20 MB/s.
I can also have 2 different jobs running a backup at the same time, each getting 50 MB/s, totalling at 100MB/s, a soon as I cancel on of the jobs, the remaining backup process immediately drops down to 20 MB/s
I cannot make any sense out of this behaviour, I would expect one job alone to run at about 90-100 MB/s and not at 20 MB/s.
And I certainly not expect the job to run faster when I start a second one at the same time and to get slower again when the second job is cancelled or finished.
Has anyone maybe a hint in what direction I should start looking at?
Thanks!
