How does a rack system simplify the use of network hardware?

Question

Just trying to work out the pro's and cons of using a rack system in my network

Answer 1

Well its a matter of space. If you use rack mounted servers you can have several in one vertical rack thus taking up less physical space. You also can integrate additional switches routers etc into the same rack again taking less space and making management easier as well as easier connections and easier cabling.

When you look at expense you will see the downside.
Really unless you have multiple servers in the same location the cost will probably outweigh the advantages.
