Hello All,
I've installed a new Netapp 2240-4 and am in the process of migrating VMs from my old iSCSI SAN to NFS Datastores on the new Netapp. Once I switched from san transport mode to nbd transport mode I experienced fairly severe backup throughput degredation. I understand that this is because traffic is now being streamed from the ESX service console port instead of the storage fabric. I'm seeking assistance in figuring out if I can support hotadd transport mode to get this traffic off of the network my current service console port is on. I am a bit unclear how to implement a hotadd server to make use of my tape backup device. If my configuration won't support hotadd, I am looking for assistance in ways to improve the service console throughput to increase my backup speeds.
