There are a lot of ways to put network resources together. One of them is to consolidate all of the servers into a single area. Server racks can also serve to consolidate the cabling and wiring between many different networks and it is for this reason that they will probably be more widely used in the future. They might even become an assumed part of office infrastructure.
Typically, server racks can be put together through screws that are found in the base of the server racks and they can be put together based on several different applications. Today, a modern computer is several billion times more capable than an earlier computer would have been. In a short period of time server racks have changed completely.
And it is for this reason that office space has had to adapt to track with the changes to server racks. It is uncertain whether or not server racks will continue to be an essential part of office infrastructure, but they probably will unless the way that businesses operate change entirely.
For instance, it is possible in the future that businesses will become more decentralized and the people will instead work from coffeeshops, from their houses or elsewhere. Work is becoming more defined by telecommuting, and that might define the future of the office. Eventually, people might end up getting server racks in their apartments so that they can host five or six different co workers at once.
Nonetheless, for the moment, people will probably continue to have these racks installed at the office. Working face to face is still the best way to work, and it is for this reason that people will probably continue to work in this way.
