The primary factor that determines the lifetime of servers available for deployment is performance. Power outages turn off the network offline, and even damage motherboards, memory, and hard drives. Because the internal resource is to connect businesses to their networks, only 2 to 3% of deployment options have the appropriate power supply systems. 97% of the other most often do not have redundancy several units also carry the energy load, even if a unit fails or has a unit running above . other units overload and fail. Every part of the power system – UPS, switches or circuit breakers, generators and power distribution units (PDUs) – must be redundant and under capacity.
first Task 1: Non-redundant power networks
To compensate for power failure, multiple PDUs connected to various network networks and multiple UPSs must be designed to compensate for network distribution. Placement facilities with redundant power grids can simultaneously connect client servers to different networks, so even when it is offline, the other will work and the network will continue to function smoothly.
2nd task: Non-redundant UPS
Uninterruptible power supplies provide a power outage during a power outage until the generator is online; if the uninterruptible power supplies do not turn on immediately at the time of the fault, the network stops. Even high-quality UPSs are often malfunctioning, so it is critical to have multiple redundant UPS units in the "n + 1" configuration – all in the UPS plus an extra. Functionally, this means that all UPSs are working properly to handle device failure without overloading other units. If there are two UPSs, each unit should be below 50%, if one fails, the other continues without overloading. If there are three units, each must be below 66%; four units, below 75%. The current load is displayed on the front display of the UPS.
3rd Task: Transmission Switch Failures
Most installation options use mechanical transmission switches that are less reliable than circuit breakers to connect power from the utility to the generator. These switches are one of the most common places where power does not work. Without redundant switches switching performance at the same point, failure of the switch means that the network stops.
4th Task: Insufficient Generator Capacity
Generators provide power supply during shutdown. Without overloading, the generator must have the capacity to be 1.5 times the total building load. Ideally, the installation facility should have a redundant backup generator in the event of a primary generator failure and the facility must have a process for power generation between generators. Several generators are not the same as redundant generators. One of the most common problems with installation options is that the installation started with a small generator and added generators. This creates more points where performance is to be transferred during the transition, increasing the likelihood that the network will go down. From a practical point of view, the generators are well maintained, tested monthly, and equipped with fuel.
Of the 20 deployment options, less than one has the best power supply systems, as power systems have the greatest impact on network operating time. Without well-maintained and redundant components running on all parts of the capacity, network performance, server performance and equipment life span. To ensure that the power supply system in the installation facility is strong enough to handle power and equipment failures, two words should be noted: capacity and redundancy.
