In February, Server Technology introduced Sentry Power System, which builds a software layer upon its Quality Power Architecture (QPA) and is an evolutionary update (and proper superset) to its existing hardware and software offerings.

Sentry Power System raises the bar by including Server Technology’s exclusive SNAP technology, a revolutionary secure XML technology that tightly integrates ServerTechnology’s Sentry PDU hardware and Sentry PDU management software, effectively creating a single system of power. It enables true Plug-n-Play operation and global management of all PDUs and simplifies ongoing management of Server Technology’s PDUs (including outlet state changes, thresholds and alarming, group and outlet configuration, IPv6 and SNMPv3).

Server Technology introduced 300 new products into the rack-mount power distribution unit space in the last 12 months, bringing its overall offering to more than 2,000 products.

New key product line introductions include Smart POPS (per outlet power sensing) and PIPS (per inlet power sensing) features. POPS is for data center managers who need individual device level power measurements with secure outlet power that is always on. PIPS gives data center managers accurate and granular rack power information.

Server Technology also introduced Sentry Power Manager v5.1, a significant upgrade to its power measuring and management solution. It’s the most feature-rich, comprehensive version yet with unique industry-first functionality, SPM’s new Plug & Play SNAP features asingle pane of glass dashboard making managing an entire PDU network easier.

Through the at-a-glance data center power views, customers can manage, auto-discover, individually and group configure and upgrade all of their networked PDUs.

Customers have a choice of application – virtual or appliance and a choice of system – middleware for data center infrastructure management (DCIM) or building management system (BMS) integration or stand-alone data center power monitoring.


Server Technology’s three dozen patented innovations in rack-based power have enabled it to create its unique Quality Power Architecture, used across its entire PDU hardware product line. QPA ensures that Server Technology’s PDU designs continue to perform to rated specs over their entire lifespan and ensures levels of service and reliabilwity.

As power demands continue to rise and service levels continue to be tested along with the desire to raise efficiencies across the board, QPA enables Server Technology to deliver almost any style of data center power, from traditional approaches and high-density blade configurations, up to and including 400/415 and even 277/480 volt PDUs. QPA also enables customer-centric designs to be created quickly and efficiently with the same high reliability found in every Sentry PDU device.


Power densities will continue to increase with more demand for high-density products such as 3-Phase products with higher current ratings. Companies are also reverting back to a large number of smaller ‘pizza box’ servers that are low profile (1U) and lower power draw-just more of them. In response, Server Technology brought out several new PDU products with higher outlet count to match.

There is also a push for green, more efficient facilities. More companies are looking at the tried and true 400/415V infrastructure (that most of the world is already using). In addition, some customers are examining whether they should implement 277/480 V solutions. Server Technology has developed new products to address both of those needs.


The US Department of Defence Joint Interoperability Test Command JITC) has used Server Technology for data center power management and monitoring in its lab testing facilities.

JTIC is an independent evaluator of information systems for the Department of Defence, responsible for interoperability testing of network devices that will be connected to the Global Information Grid.

Sentry Power Manager (SPM) records power usage information on all JITC-tested products from the Server Technology PDUs and JITC uses that data to chargeback power expense to the individual companies that are having products tested. Server Technology President Brandon Ewing says: “JITC needed solid power distribution and control, along with the granular energy usage information needed to bill their internal customers for all of the costs associated with running their tests over extended periods of time.”
