Slow Quick Migration on 10Gbit network

[Isotop7]

I'm quick migrating servers between two ESXi-Hosts in a vSphere Essentials Cluster without vMotion. Both servers are connected to a 10GB Dell N4032f.

If I'm migrating VMs from host 1 to host 2, I only get processing rates between 50 and 70 Mbit/s.

Any ideas?

I'm using vSphere 6.5 for the cluster and ESXi 6.0.0 for the hosts.

Kind regards,

Hi,

1. Can you share what were the bottleneck stats during the processing.
2. Do you have backup proxy servers with access to source/target datastores on both hosts? Thanks!

1. The mean bottleneck stats are <10% source, ~20% proxy, <10% network, >90% target.
2. The veeam b&r server runs on host a. On host b there is no proxy.

Is there something like san-mode for non-shared host datastores or would this be hot-add with proxies on each host node?

1. The bottleneck target means that the job spent most of the time on writing the data to the target datastore.
2. Since you are migrating onsite, you can use a single backup proxy with the access to both datastores.

No.

You can utilize Hotadd transport mode for the quick migration, but you need to deploy at least two backup proxies. Thanks!

Access in what kind of way? Access via vSphere appliance?

Would this speed up the migration?

Thank you in advance

You should deploy a backup proxy on each host with the local storage for utilizing Hotadd mode.

It depends not only on the transport mode, but utilizing the hotadd mode might improve performance. Thanks!
