I think the update has really got me into a big trouble. After I did the upgrad from 10/100 d-link switch to GS748Tv4 when I tried to run a backup to to an iscsi drive number of problems arrived altogether. According to me I have made my iscsi connection limited to only one server and also made it concerned to only Symantec backupexec storage. Now the main issue arrives after when I run the backups, actually during that period of time I have noticed a lot that all my bandwidth available on the network are used up with the backups process and along with that all other network related activities completely fails. All this happens just because of the network conjunction. However all these problems doesnít really affects me as I usual go for running the backups only during late nights when I do not prefer to do any sort of work but donít know for what reason the backups sometimes run the whole night followed by the next day which then restricts me do my personal work. These long running backups always create a lot of mess within the network. Now as far as I know I need to do something with the iscsi driver. I just wanted to know whether there is any way to lower the priority of the port to the iscsi device keeping this switch and on the other hand also let me know the way to give more priority to the other traffic on the network. All in all I just need to have a balanced traffic so that I can also able run the backups smoothly and also do other necessary things on the network. If balancing is not possible then lowering the iscsi-related network traffic is also fine for me. Hope I have made almost everything clear and now I would expect some positive suggestion and solution for this problem. Please help me out as soon as possible.
