iSCSI Problem

[mrbios]

Hi,

I’ve got a problem with a Windows Server 2016 box, HP DL360p Gen8, running Veeam 9.5u3.

I’ve got two network connections to the box, one to my infrastructure network for general server based connectivity, that’s on a 1GB NIC. Then i’ve got a 10GB NIC that’s connected to my iSCSI network.

Virtual machines correctly backup in SAN transport mode for my Disk to Disk based backups.

However I’ve just noticed that my Disk to tape backups are reading data using the 1GB link for some reason. Just to clarify, the disks being read from in this scenario are on an iSCSI storage device.

I attach the below two images that hopefully paint a better picture of what is happening:

Top image shows my infrastructure connection, the bottom shows iSCSI. Any recommendations on how i go about resolving this?

Ok, I’ve manually set the source in the iSCSI initiator, forgot all about those settings if I’m honest! However it seems to get to roughly 2gb/s then randomly drop out and spring back again, and even though the connection is supposedly using twice as much bandwidth, I’m not seeing a processing rate any more than 14-15mb/s faster than i was previously.

See image below:

Crisis over, it appears to have righted itself, presumably just needed a bit of time to right itself after i changed the iSCSI settings.

However I am still a tad confused as to why it was opting to use the other NIC, while VM backups to the other SAN were connecting correctly.
