Link Upgrade

Our network admins are considering allowing our clients to upgrade from 100MB to 1GB. Currently most of the siwtches are set to only allow 100mb from the client workstations except for some of the heavy users in IT and Marketing. I am wondeing if anyone has any expericne in doing a simular upgrade. My concerns are that there may be additional loads on our servers like AD, Exchange, CIFS shares ect. and want to guague what we should be focusing on if there will be any impact from this upgrade. All of our servers are either 1GB or 10GB. Any suggestions or words of wisdome are appriciated.

Thanks.

A WAN link upgrade from 100MB to 1GB should not affect any of your services (AD, Exchange etc). This only area where i would look into is if you have Site Links in Active Directory that are based on a weighted value for routing purposes you should make sure that you update them accordingly. A side from that there is nothing really to affect.

Users that have 100MB at the client level will continue to operate without issue at 100MB. Users that have 1GB connections will need to be connected to a GB switch to take advantage of the higher throughput.

Sorry this is a LAN not WAN upgrade. We are looking to upgrade all of the computers in the building from 100MB to 1GB.

Thanks.

Even though it is a LAN upgrade still shouldn't matter. From a services perspective it should all work the same. This would be more appropriate question for the networking zone. Active Directory and Exchange should not be affected.

I am mostly concerned with the amount of load that can happen on our servers, example outlook users that sync there OST files in the morning will now be able to sync at 1GB instead of 100MB. People on file shares accessing, copying files will also have more bandwidth that could load down our servers.

When you upgrade you network regardless of 1GB or 100MB the user transfer rate will be higher (if everything is set properly switch/client NIC/physical media CAT5 etc) if everything is in place they will be able to transfer data faster because the speed is available. This will not affect server performance as the additional speed is available from a Network/Physical layer.

Just becuase you are currently running 100MB right now (user transfer rates are slower) does not mean your server performance will be impacted. If anything it will be better as there could be less bottle necks if you go to 1GB connections.

Clients/Servers having a higher connection speed to an applicaiton server is not going to impact the server. It just means the servers/clinets requesting the data will have a higher throughput (fast road) to travel on.
