“Understanding The Cost Savings Associated With Results From a CFEP”

Wasted energy is wasted money.

All too often, hidden costs associated with inefficiencies and wasted energy consumption in today’s Data Centers go unnoticed and are simply accepted as the cost of running a mission critical business. As a facility’s monthly energy bills show only the total charge incurred, many Facility and Data Center Managers are operating without the knowledge of what their data center architecture is costing them on an annual basis.

UNS, LLC specializes in establishing energy efficiency benchmarks and provides cost-effective, energy efficient power, cooling and management solutions.  A company that differentiates itself from its competitors by focusing on achieving maximum energy efficiency in the shortest time possible, is now offering their Critical Facility Energy Profile (CFEP) absolutely free.  Using a non-invasive, risk free approach, our CFEP service inspects and analyzes a critical facility holistically, then identifies potential conflicts and makes recommendations on how to improve the overall reliability and energy efficiency of their IT support assets.  Upon completion, a CFEP Report Card is provided which summarizes each critical support component and its associated costs, based on deployment and facility architecture.  Understanding and applying the recommendations noted in the CFEP Report Card, a 20-30% increase in energy efficiency is a typical ROI from customers that have had a CFEP performed.

UNS is committed to understanding our clients challenges and strives to provide them with the tools needed to operate their business with reliability, lower operating costs and maximum efficiency.  Let us help your company get more from its I.T. budget by spending less!

Don’s Corner: “Frustrated With Replacing Parts In Your Discontinued Silcon UPS?”

Posted by on May 12, 2011  |  No Comments

Don Melchert, Critical Facility Specialist

A common problem many Data Center Managers are facing is their trusty APC Silcon UPS has now reached its end of life and parts are running out.  It begs the question: Act now, or wait until it breaks?  I suggest we ask ourselves one more before answering. How bad will the “break” be when it comes?  Consider, aged capacitors can and charge circuits might not allow your batteries to charge and discharge the way they used to, resulting in more frequent battery changes.  Constant running, multi-speed fans have a life expectancy of 3 years.  Should they fail, the internal safety mechanisms present in most UPS systems force a shut down on high heat.  Even if it’s a simple fix, parts may no longer be available, or at best, require longer shipping times due to proximity of existing stock.  To plagiarize a little, maybe we should be asking, “To rebuild, or not to rebuild?.” I don’t know about you all, but I can’t be down for two weeks!

Note:  The APC Silcon Series UPS was discontinued in September, 2006 and is no longer being manufactured.  APC has agreed to support the units from a maintenance standpoint, however, parts will not always be available for immediate replacement.  Components not readily available, such as the Inverter sections and Capacitor banks, will need to be custom built, resulting in mean time to repair rates of greater than two weeks.

It’s significantly important to keep up on the manufacturer’s recommendations.  If you have a lapse in your service contract and want to renew, most manufacturer’s require the unit to be up to date on revisions. This includes end of life internal components such as fans and capacitor banks.

We would welcome an opportunity to discuss the various product replacement options for the APC Silcon Series UPS.  APC Smart-UPS and APC Symmetra PX line of products are excellent considerations based on your facility’s specific requirements.

Hot-Aisle Containment vs. Cold-Aisle Containment….A Lesson In Efficiency

Posted by on May 10, 2011  |  No Comments

Waite Ave, Managing Partner

High energy costs and spiking data center energy consumption rates have forced data center professionals to rethink their data center cooling strategies. Although traditional cooling approaches (such as perimeter cooling through a raised floor plenum) are still quite prevalent, new approaches such as hot aisle and cold aisle containment are making significant inroads.

Watch the Video from Hot-Aisle vs. Cold-Aisle Containment:

HACS vs. CACS Video

The Cold Aisle Containment System (CACS) is typically deployed in traditional perimeter-based cooling environments. Traditional cooling environments use the entire room as a hot air return plenum and use deliver cold air via the raised floor plenum to the cold aisles. The CACS encloses the cold aisle allowing the rest of the data center to become a large hot air return plenum. By containing the cold aisle, the hot / cold air streams within the data center are separated.

The Hot Aisle Containment System (HACS) encloses a hot aisle to collect IT equipments hot exhaust air and cools it to make it available for IT equipment air intakes. This creates a self-contained system capable of supporting high density IT loads.

Mixing of hot and cold air streams in the data center lowers availability of IT equipment. Returning the warmest possible air to the computer room air conditioners increases the efficiency and capacity of the system. The HACS ensures proper air distribution by completely separating supply and return air paths.

The design of HACS assimilates many of the advantages of the CACS and avoids many of the pitfalls. When upgrading a data center to be more efficient and less costly to operate, any move away from the traditional perimeter cooling approach is a step in the right direction. While CACS is a “better” scenario compared to traditional approach, the “best” scenario is embodied in a HACS system.
