Unavoidable Change in the Data Center and Information Technology Industry


Data Centers are being built at an accelerating rate!

We hear unbelievable emphasis all the time about “availability”, “how to build more availability in a single data center site or facility?”,  “N+1”, “N+2”, “2N”, and “2N+1” guidelines all relevant to site and facilities infrastructure.  But are we correctly addressing the issue of availability?  Are we defining availability correctly?  What are we trying to achieve via so much emphasis on such narrow and incomplete aspects of a bigger picture?  Are the notions of resilience and availability truly all that matter?

Every time I meet fellow colleagues, businessmen, engineers or technicians, the discussion centers around the benefits of cloud computing, yet the legacy standards don’t fully capture its efficacies and fail to integrate them into a meaningful bigger picture. 

We still see data center facilities being certified as 99.995% or 99.982% available by legacy certification bodies, and those metrics are good to know. But is it sufficient to only evaluate and measure a facility’s infrastructure design and capabilities without any indication of how that facility fits into the overall topology, or how well it’s design is aligned with application requirements? Do such certifications inform the business as to whether that design for that facility is the best option over other alternatives, or can it only evaluate the facility at hand? While a particular high availability facility’s architecture may serve the application sufficiently, perhaps a topology of facilities - each designed to a lower availability specification - would have produced the same or better overall result at a lower cost and with less operational complexity. Our existing toolsets have been ill-equipped to provide such guidance.

Further, The high availability site that is rated with all those shiny nines, with its golden fault tolerant UPS & generators may have deficiencies in its operational characteristics, such as SLA’s, SOP’s, documentation, governance, personnel competency, etc. that will negatively affect its availability, yet none of the actual standards have the ability to comprehensively evaluate all of those important characteristics both at a component level and as a holistic system when looking at an infrastructure.  The same thing applies to deficiencies in cyber-security, or an application’s robustness and resilience, and the many other factors that can introduce extreme vulnerabilities to the application delivery architecture and infrastructure.

Where are the metrics that identify, evaluate, calculate, weigh & show the exact score of an entity’s application delivery capabilities, globally?

Isn’t it as important to be redundant, yet remain efficient? What about sustaining capacity?  How can a facility be considered available, even in consideration of its redundancies, if it lacks the required capacity? How about safety & security? What are the prerequisites to design a 99.995% available data center “node”?

These are questions that industry professionals are still searching for the answers to.

There are many standards, each setting metrics for a particular technical domain, but not a single universal standard that encompasses all domains under its umbrella, with all their inherent interdependencies, to create a balanced & quantified macro-view of the data center, infrastructure, information technology and cloud platforms that converges to a unified grading scheme. That very scheme will be the absolute grade to compare apples to apples & not apples to oranges!

Often, we hear about PUE, and how some organizations are reducing it down to fantastic values. But how can we benchmark a PUE in Alaska and compare it to a site in the tropical climate of the Amazon? Wouldn’t such benchmarks be useless for comparison purposes? What about the data center facilities that are using renewable energy & innovative power generation? How do current efficiency metrics factor in such efficiencies?

The mindset that the infrastructure availability is everything has changed. The mindset that PUE is measuring the efficiency of a data center comprehensively and all we must do to save energy costs is bring our PUE down, is misleading. The mindset that power & cooling are the sole infrastructure elements is completely iniquitous.

We are now living in the era of modern information technology, the era of software defined networks, virtualization and cloud computing where everyone is focusing more and more on the end goal:  the delivery of the “APPLICATION”

The Infinity Paradigm® will reshuffle all cards.

Think about it!

Reconnecting leaders with their employees

Image
By Dr. Brian J. Haw.  Dr. Haw is Associate Director of Technology at AT&T Mobility Services LLC We are all very aware of the speed in which IT moves and its impact on our lives, our application ecosystems, and specifically our data centers. To keep up, we make adjustments… choosing cheaper suppliers, shortening deadlines, and right sizing the workforce. The life’s blood of our industry is adapt or fail and necessary calculations are made to keep the machine running. In essence we are re-prioritizing what is important for the current environment. But, perhaps, it is time for us to pause and rest our intentions and align them with what our core values should be. The question then comes to pass, what of the workforce? Are the people that work for us agents geared toward meeting metrics or can they be something more? Do they still have a seat at the table for value creation? Our solution is to adapt by fielding a human-centric approach to leadership. We be...

COVID-19 is stress-testing applications and global data centers

Image
By Mehdi Paryavi, DCA®, CLA®, DEA®.  Mr Paryavi is the Chairman of IDCA Putting to test the underutilized facilities, overutilized resources, and unmanned infrastructure… It has been a long time I haven’t had the chance to write a blog, now writing this in a time that the global pandemic, COVID-19, is testing humanity’s patience, as well as our applications and data center capabilities globally and more radically than we are used to… “Numerous applications out there may have never been tested to such degree of an unexpected surge in application peak time and prolonged use.” Numerous applications out there may have never been tested to such degree of an unexpected surge in application peak time and prolonged use. In parallel to this surge, a steep rise in cybersecurity threats and application vulnerabilities can naturally be expected. Are we prepared for what has already arrived at our door-steps? What are we doing to prepare for the post-corona-era?  “Glob...

A Standards Framework for the Applications Ecosystem – The Infinity Paradigm

Image
The Infinity Paradigm Standards Framework from the International Data Center Authority (IDC-A.org) is the latest and I believe most complete standards set for IT. Many of us have participated in efforts to create a method to measure the value, effectiveness and efficiency of our IT infrastructure but I believe this to be the most complete by far. Early efforts to improve infrastructure efficiency came from The Green Grid with PUE, followed by WUE, the Data Center Sustainability Metric and the Data Center Maturity Model. There have been other efforts to improve communication and resiliency like the Data Center Pulse “Data Center Stack” and most recently Infrastructure Masons released their data center rating system . The aforementioned efforts helped to put focus on and provide measures and metrics needed for improved management and ownership of critical and costly IT infrastructure. In the case of the Infinity Paradigm perhaps the most important factor is the notion of treating yo...
