Are we Ready for Energy as a Service

Not sure if everyone saw the release yet but it was a big one. Our CEO introduced Cisco EnergyWise at Networkers Barcelona on Jan 27, 2009. For me personally it was very gratifying to see this solution come to market as there have been a small core group of, well…energy-wise people pushing this tirelessly for many months. The real credit goes to the developers and you can see their take on things here.What they’ve done and in many respects what we’ve done as an industry is huge in the context of Green, energy, the economy and to organizational structures supporting the business. I personally see it as the first major accomplishment in the new Green IT market. Not the moon landing yet but its at the very least a Sputnik. Why you say? Well with a simple code upgrade to IOS, you can now use your existing Cisco network as the monitoring and control plane for energy for just about anything you can IP address. You also do this in more or less the same way you manage any Cisco network today. Sound too Ginsu to be true? More on the inner workings here. EnergyWise marries up with our Richards-Zeta acquisition also announced on January 27th. RZ will provide us with mediation into building management systems allowing for a complete picture of energy use enterprise-wide.What I am really curious about is are we ready to adopt energy as a service we manage? Network Managers already handle security, voice, load balancing, countless volumes of routing tables and so on. How will taking on what is arguably the most critical service for any business change what we are doing today? I’m interested in hearing some thoughts on how everyone thinks this will play out? Especially any Network Managers who are curious, skeptical or otherwise. Read More »

WAN Optimization and Visibility: Have Your Cake and See It Too…

It’s interesting that despite the fact that WAN optimization has gained a lot of visibility over the last 4+ years, there are still some generalization about the technology that prospective buyers need to be better educated on. Take this story in Network World today on the topic of WAN optimization having good upside in the current depressed economy.While the “upsides” of reduced WAN costs are well covered — especially as traffic volume continues to grow through VoIP, video, etc — the one caveat called out is “lack of visibility”, with the recommendation of “IT organizations should think twice about doing that if it means they lose visibility into what is happening on their network.” Read More »

Tons of Data Centers Closing?

I had an interesting Twitter conversation with Robert Scoble over the past week or so. Robert asserts that, “you must have missed the financial crisis. This is forcing TONS of companies to get rid of data centers or minimize them.”I respect this opinion. However I talk to a lot of people in this space and I do not intrinsically share this opinion. Here are some of my observations:What I Have NOT SeenAn example of a company getting rid of a data center without consolidating it into a larger facility.A reduction of workload, application, or storage requirements.Holistic outsourcing of an IT infrastructure to a cloud or hosted provider for a sizable business.What I Have Seen- Data Center Consolidation projects, sometimes coupled with a decommissioning, most started in the past five-years, yield tangible benefits by consolidating computing resources together, usually into denser, higher power, more available data center facilities.- Companies use Virtualization technologies to consolidate virtual machines onto a smaller number of servers that have the memory, CPU, and I/O architecture that enable greater workload consolidation. -- VM’s proliferate like Tribbles throughout the enterprise driving workload demands back up quickly.- Enterprises look toward cloud computing offerings and holistic managed offerings to defer risk, capital expense, and achieve linear operating cost growth with workload/application deployment. I don’t disagree that the fallout from the economic crisis is real, of that I have no doubt. What I question is if it has forced the workload reductions necessary to actually reduce the IT Infrastructure required to support line-of-business operations. There is also the time-factor. Data Center builds take years, application migrations take years. We are not far enough into the financial crisis for it to have been the cause of a data center migration or decommissioning… yet.dg

Can you help me write this paper….

I spent a redeye flight to Barcelona last week to pen draft-1 of this doc. Then added a few things in from internal feedback. But before publishing this anywhere and doing the usual lobotomizing to the doc to make it tighter and such I wanted to submit it ‘in the raw’ and get direct feedback… The attempt here is to discuss ‘What is Cisco’s Virtualization Story’ and then discuss how Virtualization affects IT architectures, business benefits, how to evolve an IT architecture to embrace Virtualization and a bit of discussion on what we need to do in the network to embrace, enable, and accelerate virtualization.Please feel free to comment, suggest edits or changes. Maybe I have it totally wrong, maybe I need to explain some things more clearly. But your input and feedback would really help make this clearer for people. /snip Source File in Word Format Read More »

Is there a tool that does…

So am using Google Reader to read my feeds I subscribe to, also using Google News for on-demand news emails to me for key terms I track. (cisco+nexus, cisco+data+center, etc). Is there any way to combine these or a tool/mashup that I am not using but should that lets me read through my subscribed news feeds, but also does key term searches of the aggregate of blog-rolls and news feeds so I can then be more accurate on the ‘what I am reading’ section. Right now I have to subscribe to the RSS feed to be able to post it. dg
