What are the advantages to using VLANS
Posted on 2014-03-01
I think I need to revert back to networking 101. I have three buildings connected via fiber optic. All three buildings are on the same domain. Each building has a DC. One big subnet. All three buildings are using ProCurve switches.
7 computers in building 1, 40 computers in building 2 and 70 computers in building 3. Total of 117 computers. It use to be with hubs that only one packet would get through to the destination and all the other packets on the line would get rejected and have to retry. Is that still the case with switches? Is the way I have it set up wrong?
A few departments in building 3 are complaining of speed issues with SQL. The SQL server is in there building. I have checked server and switch utilization and everything seems find. I am afraid that just the way I have the network designed (117 computers on the same segment) might be causing the problem. Thoughts?
Would using VLANS help?
