The Data Center is Dead

by Dave Cappuccio  |  July 26, 2018

Infrastructure and operations (I&O) leaders today face a daunting challenge. The IT they have known for decades is changing — radically. IT’s primary function will be to enable the business to be more agile, to enter new markets more quickly, to deliver services closer to the customer, and to position specific workloads based on business, […]

Enterprise Workload Monitoring – Bridging the Gap Between Data Centers and the Cloud

by Dave Cappuccio  |  September 29, 2015

The never ending dilemma of IT and business;  the easier we make things, the more complex they get.  Almost every enterprise I talk with today is going through some type of transformation from historical compute solutions (running it in “my” data center) to a hybrid environment.  Now, the definition of hybrid will vary wildly depending […]

Future Data Centers are Not Software Defined, They’re Enterprise Defined

by Dave Cappuccio  |  May 24, 2015

There are times in life (and especially within IT) when we must realize that not all things can be delivered (and defined) by software or marketing.  I suppose this realization comes after years of seeing interesting ideas in software and delivery models turn into marketing hype and a distorted understanding of what the market could, […]

The Evolution of Fit For Purpose or Micro Data Centers

by Dave Cappuccio  |  June 20, 2014

For the past umpteen years there has been a trend towards consolidating data centers – from many sites to as few as possible.  Or if building your own data center wasn’t plausible, consolidating from owned sites to leased, hosted or collocated sites became the option.   Arguably there are many valid reasons to consolidate, and […]

Shine Some Light on Shadow IT

by Dave Cappuccio  |  November 27, 2013

You may have heard the term shadow IT bandied about lately, in both analyst musings and the industry press (they often feed off each other in the always fascinating game of buzzword bingo).  What’s interesting about shadow IT is that it’s really nothing new, but rather something thats been with us for years, but the […]

by Dave Cappuccio  |  July 2, 2013

The DCSE Metric: A simple way to look at data center space is to analyze the effective use of space by existing IT equipment, relative to the total available space for IT. The DCSE metric factors in both Horizontal Space Utilization (HSU) and Vertical Space Utilization (VSU). Vertical Space Utilization (VSU) VSU = Installed IT […]

Software Defined Data Centers – Hype or Reality?

by Dave Cappuccio  |  July 1, 2013

Our industry just loves new catch phrases – and when a new one catches on the vendors and press can get amazingly creative is assigning that phrase roles and responsibilities that go far beyond its original concept.  In the recent past it was all about cloud computing.  Once the industry grokked the concept of “cloud” […]

Rack Unit Effectiveness–A Useable Data Center Metric

by Dave Cappuccio  |  November 9, 2012

Data Centers have gotten a bad rap of late, with both the press and senior executives putting pressure on them to improve overall efficiency and reduce operating costs (yet again).  The focus for the last few years has been around energy efficiency and the PUE (Power Usage Effectiveness) metric developed by The Green Grid.  PUE […]

The Case for the Infinite Data Center

by Dave Cappuccio  |  June 7, 2012

When faced with planning a new data center the question of how much space will be needed is potentially the most difficult to determine. That said, the answer is often one of the quickest made – with the least amount of analysis, and I would suggest that it is rarely correct, and in most cases […]

Steps to Ease Data Center Cooling – Number 5

by Dave Cappuccio  |  April 6, 2012

Cooling with the data center has become our achilles heal in many cases. Historically the folks in IT had relatively nothing to do with heat or cooling management, this was strictly under the purview of the facilities team (after all, if it wasn’t IT gear, it didn’t count). In todays world though the IT team […]
