Просмотр кода страницы Four Power Program Difficulties Common in Colocation Facilities

The primary element that determines uptime for servers in a colocation facility is energy. Power outages will knock a network offline and even damage hardware such as motherboards, memory, and challenging drives. In spite of how intrinsic energy is to keeping corporations connected to their networks, only two% to three% of colocation facilities have the proper power systems in location. The other 97% of facilities most generally lack redundancy, numerous units carry the energy load even if one unit fails, or have units that are running above capacity, so a unit failure will cause the other units to overload and fail. Each and every component of the power method uninterruptible power supplies (UPS), transfer switches or circuit breakers, generators, and power distribution units (PDU) must be redundant and operating beneath capacity.<br><br>Dilemma 1: Non-redundant Energy Grids<br><br>Numerous PDUs connected to separate power grids and multiple UPSs ought to be designed into the colocation facility to offset a energy grid failure. Colocation facilities with redundant energy grids can connect consumer servers to various grids at the same time, so that even if one goes offline, the other will perform, keeping the network operating without interruption.<br><br>Problem two: Non-redundant UPSs<br><br>The UPSs provide energy during an outage till the generator can come on the web if the UPSs do not turn on quickly at the time of failure, then [http://www.ai.net/networks/networks-overview maryland internet] the network will go down. Even with high good quality UPSs, failures are widespread, so it is crucial for there to be several redundant UPS units in an n+1 configuration all of the necessary UPSs, plus an extra. Functionally, this signifies that each UPS runs sufficiently beneath capacity to manage a unit failure without having the other units overloading. If there are two UPSs, then each and every unit must run below 50%, so that if one fails, the other can continue without having overloading. If there are three units, each and every ought to run below 66% four units, beneath 75%. The present load is shown on the display on the front of the UPS.<br><br>Dilemma three: Transfer Switch Failures<br><br>Most colocation facilities use mechanical transfer switches, which are not as reliable as circuit breakers, to switch energy from the electric utility to the generator. These switches are a single of the most widespread places the power program fails. With out redundant switches to transfer energy at the exact same point, a transfer switch failure will mean that a network goes down.<br><br>Problem 4: Insufficient Generator Capacity<br><br>Generators provide energy in the course of an outage. To run without having overloading, the generator need to have capacity to run 1.five times the total creating load. Ideally, a colocation facility must have a redundant backup generator in case the major generator fails, and the facility should have a process in location for switching power in between generators. Getting numerous generators is not the very same as getting redundant generators. A single of the most typical generator difficulties with colocation facilities is that the facility began out with [http://www.ai.net/data-centers/data-centers-overview maryland data center] a tiny generator and added generators as it grew. This creates numerous points where power has to be transferred throughout an outage, rising the likelihood that a network will go down. As a practical consideration, the generators ought to be well-maintained, tested monthly, and fully supplied with fuel.<br><br>Points to Consider<br><br>Fewer than one particular in twenty colocation facilities have the finest power systems in location in spite of the truth that power systems have the most impact on network uptime. With no nicely-maintained and redundant components running below capacity at each component of the technique, network performance as well as server performance and equipment lifetime will suffer. To make sure that the power method at a colocation facility [http://www.ai.net/networks/networks-overview fiber connectivity] is robust adequate to handle power and equipment failures, two words ought to be remembered: capacity and redundancy.
