This morning users coming across several our WAN links complained of connection dropping to differnet servers on our hub site. We checked our WAN links and the FastE ports that connect to the Core Switch and found no trouble. But when pinging from our Core Switch to the FastE ports on the routers going to the WAN sites we got @ 850ms response time. We have our servers, switches and routers on VLAN95. We noticed a backup server that was just moved to VLAN95 was backing up server on different VLANs. We stopped the backup and things went back to normal. The Sys Admin reported that he was getting the most throughput ever on that server.
I suggested to create a VLAN just for Backups,but Sys Admin says that is a lot of work.
Question is could the VLAN95 really have been saturated by the backups of the server? I guess so since everything on that VLAN is basically on the same collison domain. If so is there a solution to this problem, maybe QOS or only using 3 of the 9 NIC cards on the server for backup?
Hope I'm making sense and thanks for your attention.
