That is centres are now designed to be able to evolve in order to accommodate growth as well as changes security needs and possible consolidation.
There has been little change in the basic design of layer 2 and layer 3 data bases for several years most of the improvements relate to increased demand for quality in terms of availability and the highest possible uptime. There have been considerable changes in the basic technology as well as some of the protocol requirements which have challenged engineers in their efforts to produce data centres that can live up to modern design requirements.
It is now considered essential that data centres are highly flexible in that they are capable supporting any new services without drastic changes to its basic infrastructure.
They must also be highly scalable meaning that they are capable of adapting effortlessly to growth without causing any disruption to the end user. There also needs to be a high level of availability this means that the data centre should be capable of maintaining its uptime without a single point where failure could occur.
Internet data centres known as, IDCs, are usually constructed to suit a particular service providers needs, they are not generally “off-the-shelf”. Those companies whose business is centred on commerce conducted mainly on the Internet will also build their own particular brand of IDC’s.
The structure of IDC’s for these so called “enterprise” companies although similar to those built by service providers will usually have less ability to be altered in such areas as scalability.
Corporate data centres are built to suit the requirements of individual companies’ business models. They may offer differing types of functions for different business requirements including intranet services, and, or, internet services.
Corporate data centres may be connected to any kind of server farm as well as securing a connection to the remainder of an enterprise network or possibly private WAN or Internet edge. As well as a range of other, possible options depending on requirements of the companies business needs.
More recently more specific enterprise data centres have come online bowing to new needs for application environments these include concepts such as web services, n-tier as well as grid computing.
Data centre architecture is certainly far from the end of its evolution and new ideas are being developed at a rapid pace in order to attempt to keep up with changes in requirements from their clients and also uninterruptible power supply requirements.
Darrell F writing about data centres. Data Centres require uninterruptible power supplies and power protection units to ensure continuous power.
