The primary aspect that determines uptime for servers in a colocation facility is energy. Power outages will knock a network offline and even harm hardware such as motherboards, memory, and difficult drives. Despite how intrinsic energy is to keeping corporations connected to their networks, only 2% to three% of colocation facilities have the proper energy systems in location. The other 97% of facilities most frequently lack redundancy, multiple units carry the energy load even if one particular unit fails, or have units that are operating above capacity, so a unit failure will result in the other units to overload and fail. Each and every element of the energy method uninterruptible power supplies (UPS), transfer switches or circuit breakers, generators, and energy distribution units (PDU) must be redundant and operating below capacity.

Dilemma 1: Non-redundant Power Grids

Multiple PDUs connected to separate energy grids and multiple UPSs must be created into the colocation facility to offset a power grid failure. Colocation facilities with redundant power grids can connect customer servers to different grids at the identical time, so that even if a single goes offline, the other will function, keeping the network running with out interruption.

Difficulty two: Non-redundant UPSs

The UPSs provide power in the course of an outage until the generator can come online if the UPSs do not turn on immediately at the time of failure, then the network will go down. Even with high top quality UPSs, failures are typical, so it is critical for there to be multiple redundant UPS units in an n 1 configuration all of the needed UPSs, plus an additional. Functionally, this indicates that every single UPS runs sufficiently below capacity to manage a unit failure with out the other units overloading. If there are two UPSs, then each unit ought to run below 50%, so that if one fails, the other can continue with no overloading. If there are 3 units, each and every should run beneath 66% 4 units, below 75%. The current load is shown on the display on the front of the UPS.

Dilemma three: Transfer Switch Failures

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. In case you require to dig up supplementary info on go here, we recommend lots of online resources people could investigate. These switches are one of the most widespread locations the power system fails. With out redundant switches to transfer power at the identical point, a transfer switch failure will mean that a network goes down.

Difficulty 4: Insufficient Generator Capacity

Generators provide energy during an outage. To run with no overloading, the generator should have capacity to run 1.5 occasions the total creating load. Ideally, a colocation facility must have a redundant backup generator in case the main generator fails, and the facility must have a approach in location for switching power among generators. Getting many generators is not the same as having redundant generators. 1 of the most common generator troubles with colocation facilities is that the facility started out with a little generator and added generators as it grew. This creates several points where power has to be transferred throughout an outage, increasing the likelihood that a network will go down. As a practical consideration, the generators ought to be nicely-maintained, tested monthly, and totally supplied with fuel.

Points to Consider

Fewer than one particular in twenty colocation facilities have the best power systems in spot despite the reality that energy systems have the most impact on network uptime. Without nicely-maintained and redundant components running beneath capacity at each element of the technique, network performance as nicely as server performance and equipment lifetime will suffer. To make confident that the energy technique at a colocation facility is robust sufficient to handle power and gear failures, two words must be remembered: capacity and redundancy.
