Thank you to Sixto Ortiz Jr. for featuring Darren Bonawitz of 1102 GRAND on Processor.com
Bonawitz is co-owner of 1102 GRAND, Kansas City’s data center and Internet hub. 1102 GRAND is not only the largest carrier neutral facility in the Kansas City Metro area, but it is also one of the fastest growing of its kind in the Midwest. Here is what Bonawitz had to say on Processor.com.
“It is also important for personnel to be aware that water is not recommended for Class C electrical fires, says Darren Bonawitz, co-owner of 1102 GRAND (www.1102grand.com), a Kansas City-based data center. Adding water to an electrical fire will exponentially worsen an already bad situation.”

A cabinet level PDU (sometimes called a power strip) distributes electric power within a colocation cabinet. There are three important things about PDUs to ask your provider: (1) are they metered, (2) monitored remotely and (2) does you, the customer, have the ability to remotely reboot equipment?
Metered: Ask the provider whether or not the cabinet level PDUs are included in the price and if they are metered. This means there is a digital display on the cabinet showing the amount of amps being utilized. If you are on a 20 amp breaker and are at 15 amps, you are near capacity (only allowed to sustain 80% of the breaker size). That means the customer needs to order more power from their colocation provider or refrain from connecting more equipment to that power strip.
Remote monitoring: Although not a requirement, check with your colocation provider to verify whether they can monitor your power draw and alert you to issues with the PDUs operation, etc. This can give an early alert if there is a problem such as a breaker pop.
Remote rebooting: This allows the provider or customer to reboot the power of the device without being physically in front of the equipment. If you have a server lock up, with remote rebooting, power can be cycled without entering the colocation room or driving to the facility itself. Ideally they would like the ability to reboot individual outlets/devices as opposed to the entire strip.

Four things to consider when discussing power offerings with your potential colocation provider include voltages, phases, capacity and circuit breaker limit.
Voltages: Customers need to find out what voltages are offered. Common voltages are 120 Volt, 208 Volt and for larger colocation customers 480 Volt. To determine your voltage requirement(s), check your equipment to see what the manufacturer recommends, and find out if the facility can accommodate what you need. If you are using industry standard equipment, it should not be a problem to accommodate you, and it is generally possible to deliver more than one voltage via multiple power feeds or drops to your cabinet or cage. Not all of your equipment will need to be the same voltage.
Phases: Customer needs to verify the phase or phases offered. In a colocation room, power drops are either delivered as single phase or three phase. Speak to the data center or a consultant with electrical expertise to evaluate your power requirements. Verify the most effective or cost efficient way to deliver power to your rack. For example, it may make more sense to deliver a single, three phase power feed to your rack as opposed to multiple single phase power drops.
Capacities: Verify how much power is available to each cabinet, each colocation room and the facility itself. It is important because there are many facilities running out of power. The last thing you want is to move your equipment to a colocation facility only to realize months later that you cannot request the additional power necessary for your business to operate.
Circuit Breaker Limit: When you are determining you colocation power requirements, there is an 80 percent rule that is enforced by the facility and city code. If a facility is not enforcing this rule, I would consider this to be a red flag due to the potential risk. This rule limits the continuous draw of the circuit to 80 percent of the breaker size. You will want the extra 20 percent of head room in case there is a surge, you need to cycle all of your equipment at the same time, etc. For example, a 20 Amp breaker should only be loaded with a maximum of 16 Amps of continuous power draw, a 30 Amp breaker with 24 Amps and so on.
