Hello folks, we have a situation that needs inputs for SQL/network gurus.Server A - PROD SQL2005 SP3 on Win2003Server B - TEST SQL2005 SP3 on Win2003NetAppliance - a simple and dumb net appliance storage unit that holds SQL backup files from Server AAll 3 units shared the same 10/100MB switch and all used 2000/FULL duplex.Situation: trying to restore a 16GB SQL BAK file toServer B from NetAppliance. During the restore, the Server A's NIC thru-put traffic jumped from 50K/s to 76MB/s and clients in Server A notice response time dropped during the restore. The SQL restore uses an UNC command (\\NetAppliance\C$) to pull files.Notice: when we copied the 16GB file raw using Windows copy, it when very fast and doesn't affect performance noticebaly.Curious question: can anyone take stab at it as to why is it Server A is affected when it does not involves in the restore process other than sharing a switch? |
