Data Center Access Controls at the Cabinet and Rack Level

Written by Art Salazar on Thursday, April 7th 2016 — Categories: Colocation, Data Center Design, Security

As data center design continues to evolve, one stalwart piece hasn’t changed too much: cabinet or rack security and monitoring. After all, how complicated can a door lock get? While most every data center will have some form of lock on their racks and/or cabinets, especially colocation facilities as they have multiple clients accessing shared floor space, not all locks are created equal. Newer technologies allow automated access logs, biometric security, wireless unlocking, and more.

With different compliance standards and security requirements for various applications, some colocation providers will install custom locks for your cabinet if necessary. Physical security measures remain vitally important, as social engineering and theft can extend to hardware and not just data. How then do data center providers go about securing cabinets and racks?

Think Inside the Box & Implement Containment for Energy Savings

Written by Art Salazar on Tuesday, March 8th 2016 — Categories: Data Center Design, Green Data Center

Airflow containment refers to the practice of segregating the aisles of a data center so the hot exhaust air from servers does not mix with incoming cold air, while also more efficiently directing airflow into or out of the data center floor. According to the Uptime Institute’s 2014 Data Center Industry Survey, only 30% of operators have at least ¾ of their data center using some form of containment. Less than half of all survey respondents had at least 50% of their data center heat contained.

That leaves a lot of white space without any form of containment, which is one of the best ways to improve energy efficiency and translates into a more reliable environment as well as direct cost savings.

Things have improved since a few years ago, to be sure. But airflow containment remains a significant upfront investment that data center operations teams might not consider, especially at smaller providers or in-house facilities. However it can show a real ROI.

Listen to Me, Coppertop: I Don’t Have Time for Battery Downtime

Written by Art Salazar on Wednesday, February 3rd 2016 — Categories: Data Center Design

OK, so data centers don’t use Duracell batteries (ours are much, much heavier, more expensive, and specialized). I just couldn’t resist the Matrix reference.

And what data center operator does have time for downtime? Nobody, with average costs per minute hovering at nearly $8,000. This same 2013 study from Ponemon discovered that 55% of data center outages were caused by—you guessed it—UPS battery failure.

Data center UPS (uninterruptible power supply) systems are supported by dozens of bricklike batteries, and if even one of them has a bad cell, it can take down the whole system. Even a brief hiccup in power can then lead to downtime for the entire data center. Despite all this, only 48% of surveyed operators regularly tested or monitored their UPS battery health.

What types of batteries are used in the data center? How can operators keep batteries in good shape?
