Replicas Target Direct SAN Mode

[EricinIT]

Hi,

I'm trying to get some proxies to use Direct SAN on the writes to the destination side for a replication job. The source is from storage snapshot and that is using direct SAN mode. However, it falls back to network transport mode to write to the destination on the destination proxy. Both sides have the disks in thick provisioned format. At https://helpcenter.veeam.com/docs/backu ... ml?ver=120, it says "To write VM data to the target datastore in the Direct SAN access transport mode, select to convert VM disks to the thick format at the Destination step of the replication job wizard." I do not see an option here in the replication job wizard. Is there something I'm missing?

Thanks,

Eric

Hi Eric,
are u running a baseline replication (first time)?
Make sure you also read this:
"Veeam Backup & Replication uses the Direct SAN access transport mode to read and write VM data only during the first session of the replication job. During subsequent replication job sessions, Veeam Backup & Replication will use the Virtual appliance or Network transport mode on the target side."

Ok, that would explain why it goes to network mode.

Thanks!

Yes correct
It will still read from the storage snapshot but write will use a different mode.

You're welcome

It is a limitation of VMware on how you can write into snapshots. NBD-Network or Hotadd possible at the target for the regular update runs.
