Our company is buying some HP Procurve managed gigabit switches to replace some of our core switches. However, we aren't able to upgrade all of our switches from 100Mb to Gigabit switches. I think I know the answer but I'm not exactly sure. If we plug those 100Mb switches (or even a 100Mb device) into those Gigabit switches, will the performance of the entire switch drop to 100Mb or will just that one port work at 100Mb?
If you can avoid cascading switches, I'd strongly encourage it. The downsides are easily exampled with two people on the same cascaded switch copying a large file to a fileserver. Having a single user under normal usage being able to cause usage issues for multiple other users is obviously bad.
Implications are even worse with servers.
