I am here hoping you guys might be able to give me some information I can take to my owner and get the entire building rewired. We are an old school (built in 66) that has been converted to a Manufacturing plant. Currently the network is horrible. We have multiple people running Solidworks and CAMworks at the same time and we have 7 servers that are being accessed constantly; ERP, 2 Temrinals, Exchange, 2 Domain Controllers, and a File Server.
Right now all of the servers are in a rack and the servers are fairly new. We have a total of 14 switches scattered in the building for approximately 60 PC's and 15 printers. The connection right now comes in through TWC business as fiber and goes about 200 feet to our server room and then hits the filters and firewall and goes 200ft back to the origin to hit a patch panel and switch. The switch is a good 3com switch put the patch panel goes out to all of the switches scattered about and it only has CAT5 cabling hooked up. Right off the bat, nothing is gigabit.
I know this is lengthy so I will get to the questions. I am not a networking expert but I know enough to be dangerous. Lets say a user opens up a CAD file over the network. Between him and server are 2 switches and the network connection is terminated and remade twice. Is the risk of losing data everytime it hits a switch and terminates and remade again a big factor do you think?
I ran a speed test on my PC for the LAN. According to it, it takes me 3 seconds to transfer a file 100mb in size to and from the server, and there is only one switch between us and its gigabit. To send and receive to his PC is 10 seconds each. What can you guys tell me to explain to my owner that this needs to be redone?
