We are conducting a market survey of data centers in India. This is driven by an increase in interest we are seeing from customers seeking colocation and hosting services in the country of India. If you share an interest in the results of our research, or if you are a commercial colocation or data center…Details
Through some of the work that I do for my Clients, I’ve helped to identify and reduce Shadow IT as a part of better aligning IT delivery with strategic business goals. It has been sort of a mantra, that Shadow IT is a bad thing and must be eliminated. Over the past couple of years though, I’ve increasingly found myself second guessing that mantra.
While governance and security are even more important now than in times past, the characteristics of IT services have changed around us. Take end user devices for example.Details
I was having a drink with an old friend of mine, who is a very prominent and globally sought after risk management professional, and we got around to talking about Disaster Recovery Planning Software. I asked him, “have you ever found one of those that you like?” His response was not positive.
Quite often, I am called by a potential Client needing help with DR planning, and who is at the make/break point of a relationship with a DR planning tool vendor. The conversation often goes something like this:Details
I really don’t know why several of my most recent posts are about smartphones. This forum is about data center and IS security. However, I am a mobile consultant, and smartphones are a key weapon in the consultant’s utility belt. With that disclaimer, I was reading an article today in Gigaom about smartphone market share. …Details
A lot of buzz on the wire today about Apple deciding to move from the Intel chip sets in its Macbook and desktop computers, and replace with an ARM chipset. Most news sources, like this one, are quoting the story from SemiAccurate, which is breaking the news. Apple already uses ARM chips in the iPad,…Details
Following the deal between Verizon and Terremark earlier this year, Louisiana- based CenturyLink has agreed to a deal to acquire Savvis for $2.5B. CenturyLink is a fixed-line phone and Internet access company, saying that it intends to let business customers store and access data and applications over the Internet. This is a continuation of the…Details
In restaurants, airports, and public transportation I often hear debates over iPhone versus Droid. These are discussions between owners of these devices, and often times with potential owners trying to decide which phone to invest in next. By the way, I use the term “invest” very specifically, because these devices require more than writing a check. They require an ergonomic lifestyle change, which for many users comes at the price of weeks or months of “friend-making” with their new phone.
One of the topics that comes up in most of these conversations has to do with the number of applications ( “Apps” ) that are available for the phone.
The point of this chart, and the text in the associated article, is that the number of apps available for the Android is quickly catching up to the number of apps available for the iPhone. This is nice to know, I suppose.Details
For another point of view on the topic of “flat data center networks” we share the following discussion with Nic Ilyadis of Broadcom. Nic does a great job of explaining the motivation for this development, and the scenarios under which it’s a good fit, as well as advice toward building the data center network as…Details
There are a number of drivers that favor moving away from the common three and four-tier data center networks with Layer 2 and Layer 3 switching, toward a network based on Layer 2 with just edge and core switches (Get it?… ‘See what we mean by “flat?”).
Drivers for Flat Networks
One of the primary drivers for this change is virtualization. Virtualized environments, and clouds, benefit from the fluidity with which virtual machines can move across the network (and across data centers). Some common virtualization technologies are limited though, to Layer 2 environments within a common VLAN. The presence of a Layer 3 hop ads a great deal of complexity in this regard.
One reason we’ve come to know and love the three and four tier networks common in data centers is that we were forced into this architecture by product capabilities, namely port speed and port density. We’ve learned to build a hierarchy of switching because of the building blocks we had in terms of core switches, access switches, TOR switches, et. al. We must admit though, that driving packets up and down these trees of switches comes with complexity and cost.Details
Tomorrow will be the second DataCenter Dynamics (DCD) conference to be held in Atlanta, Georgia. The title for this year’s event is “Designing for Demand,” and addresses changes in the data center marketplace in terms of the impact that “the cloud” is having on the vision of the mission critical facility. On the agenda are…Details
