Hoping you can help me (and walk me through) a possible solution for each of our locations. I would like to separate the iscsi backups that are running (primarily at night) to an iscsi lun from the normal network lan traffic . I believe the best way would be to use managed switches, but if we have a few unmanaged GB switches is this possible? Can you provide an example or scenario on how to accomplish this? Do i need to set up a server or something to route traffic through since most of our switches are unmanaged at our locations? We are only backing up One Hyper-V server at each location to a synology diskstation nas. We can provide each location with a gb switch. Any help would be greatly appreciated.

Traffic isolation on a single switch is done via VLAN. On unmanaged switch VLAN cannot be configured. Another recommended (but not required) configuration for an iSCSI traffic is setting the Jumbo frames. This is also available on a managed switch only.

So, your only option is to use different switches for each iSCSI segment connected to different network adapters on the server side within dedicated IP subnets.

If the external device where the backup should go has two adapters, you can configure one in your primary network for management and another in the dedicated backup iSCSI subnet connected to the backup iSCSI switch and server NIC.

Sorry for the late reply and closing of the issue. I'm going to apply all your suggestions as soon as i can budget in some unmanaged switches for each of our office's backups.
Thanks!
