Is this a normal and secured practice?
We are moving our servers to a hosting facility and since they are only providing ethernet fiber internet connection, they are recommending to connect the internet fiber to our stacked 3750 switches on the same VLAN as a pair of ASA5510 FW (which does not have fiber interfaces). Another VLAN will be created for our production servers on the same switches. Is this a fairly common practice of physically mixing production servers with Internet on the same stackable switches even though they are separated only by a VLAN?
We have no problem spending 2K for another pair of 8-port fiber switches so we can physically separate the servers from the Internet connection OR we are just being paranoid?
Your expert opinions are earnestly requested... Thanks!
