A distributed control system (DCS) is a computerized control system for a process or plant usually with many control loops, in which autonomous controllers are distributed throughout the system, but there is no central operator supervisory control. This is in contrast to systems that use centralized controllers; either discrete controllers ...
The DCell is a highly scalable architecture where a four level DCell with only six servers in cell 0 can accommodate around 3.26 million servers. Besides very high scalability, the DCell architecture depicts very high structural robustness. [13] However, cross section bandwidth and network latency is a major issue in DCell DCN architecture.

A fieldbus is an industrial network system for real-time distributed control. It is a way to connect instruments in a manufacturing plant. A fieldbus works on a network structure which typically allows daisy-chain, star, ring, branch, and tree network topologies.
Networking allows the use of local or remote SCADA operator interfaces, and enables the cascading and interlocking of controllers. However, as the number of control loops increase for a system design there is a point where the use of a programmable logic controller (PLC) or distributed control system (DCS) is more manageable or cost-effective.
Local building codes may govern the minimum ceiling heights and other parameters. Some of the considerations in the design of data centers are: A typical server rack, commonly seen in colocation. Size - one room of a building, one or more floors, or an entire building, Capacity - can hold up to or past 1,000 servers [58]

A typical Master Control Station. On the top-side facilities of offshore oil and gas platforms, the Master Control Station (MCS) is a dedicated system that controls and retrieves data from subsea equipment on the ocean floor. The MCS is supplied by the manufacturers of the subsea control modules (SCM), an MCS is required for each vendor.
