Four Power System Problems Typical in Colocation Facilities
De Wikis en Educación
The major element that determines uptime for servers in a colocation facility is energy. Energy outages will knock a network offline and even damage hardware such as motherboards, memory, and tough drives. Regardless of how intrinsic power is to keeping businesses connected fiber connectivity to their networks, only 2% to 3% of colocation facilities have the right power systems in place. The other 97% of facilities most commonly lack redundancy, several units carry the energy load even if one 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 power system uninterruptible power supplies (UPS), transfer switches or circuit breakers, generators, and power distribution units (PDU) must be redundant and operating beneath capacity.
Difficulty 1: Non-redundant Energy Grids
Several PDUs connected to separate energy grids and several UPSs ought to be designed into the colocation facility to offset a power grid failure. Colocation facilities with redundant energy grids can connect client servers to maryland data center distinct grids at the same time, so that even if one goes offline, the other will work, keeping the network running with no interruption.
Issue 2: Non-redundant UPSs
The UPSs supply power in the course of an outage till the generator can come on the internet if the UPSs do not turn on instantly at the time of failure, then the network will go down. Even with high good quality UPSs, failures are frequent, so it is vital for there to be numerous redundant UPS units in an n+1 configuration all of the essential UPSs, plus an added. Functionally, this implies that each and every UPS runs sufficiently beneath capacity to handle a unit failure with no the other units overloading. If there are two UPSs, then each and every unit must run below 50%, so that if a single fails, the other can continue without overloading. If there are 3 units, every need to run beneath 66% four units, beneath 75%. The existing load is shown on the display on the front of the UPS.
Issue 3: Transfer Switch Failures
Most colocation facilities use mechanical transfer switches, which are not as reliable as circuit breakers, to switch power from the electric utility to the generator. These switches are a single of the most widespread places the power method fails. Without having redundant switches to transfer energy at the identical point, a transfer switch failure will mean that a network goes down.
Dilemma four: Insufficient Generator Capacity
Generators provide energy throughout an outage. To run with no overloading, the maryland internet generator ought to have capacity to run 1.five times the total constructing load. Ideally, a colocation facility ought to have a redundant backup generator in case the primary generator fails, and the facility must have a procedure in place for switching energy amongst generators. Getting multiple generators is not the same as getting redundant generators. 1 of the most frequent generator issues with colocation facilities is that the facility began out with a tiny generator and added generators as it grew. This creates multiple points exactly where energy has to be transferred throughout an outage, rising the likelihood that a network will go down. As a practical consideration, the generators should be properly-maintained, tested monthly, and fully supplied with fuel.
Points to Contemplate
Fewer than one in twenty colocation facilities have the best power systems in place despite the fact that power systems have the most impact on network uptime. Without nicely-maintained and redundant components operating beneath capacity at each component of the system, network overall performance as properly as server overall performance and equipment lifetime will suffer. To make certain that the energy program at a colocation facility is robust sufficient to deal with energy and equipment failures, two words ought to be remembered: capacity and redundancy.
