This weekend marked the migration of people to and from San Francisco – VMworld2012 attendees were headed to SFO while Burners were heading out to Black Rock City. Knowing people in both camps, I thought it’d be fun to do a little comparison list. Thirteen ways to look at Burning Man versus VMworld – acronyms, bacon, clothing and more.
This is your color-coded guide to VMworld, for the network
Sure, there will be a lot of datacenter-focused people at VMWorld. However, if you care about all the exciting things happening in datacenters, you should alao care about what happens once you get beyond the data center. Here is your short guide to finding talks, breakout sessions, and demonstrations on some of the network technologies you might want to know about. Read More »
The 2012 London summer Olympic games are now in the books. I’m sure that a lot of you watched as many events as you could. As thousands of world-class Olympians met and competed, they left us with not only their brilliant performances but also many inspirational stories.
Almost everyone is familiar with South Africa’s double amputee “Blade Runner” Oscar Pistorius. There’s also Bryshon Nellum, the American track and field athlete, who brought us another amazing story. In 2008, he was shot three times with major damage to his legs and hamstrings. Against all odds, he trained through the pain and recovered his speed. In London, he ran the first leg of the US men’s 4×400 relay team and they won the silver medal.
In the human body, the network of blood vessels is 60,000-mile long or 97,000-kilometer, centralized and regulated by a sine qua non organ – the heart. That network reaches 100+ trillion cells and is responsible for delivering blood that carries oxygen and nutrients to nourish the body (Source: National Geographic). When that effortless flow is congested (either genetically or through our own doing as a result of diet and exercise) our ability to perform essential functions becomes less than ideal. In an extreme case, such as the stoppage of blood flow to the brain, it can cripple one’s bodily function permanently.
If the data center is the heart of an organization, then the wide area network (WAN) is its network of blood vessels that carries vital data to multiple systems. For American Water (NYSE: AWK), a publicly traded water utility in the United States, this network services 300+ locations: primary and backup data centers, 275 branch offices, various production facilities, treatment plants, two call centers with between 500 and 600 workers each, and other facilities. A number of remote sites have a few hundred users, while most average 50 users. The network also provides access to applications such as Lotus Notes, MS Office, ERP and CRM, and numerous other applications for data replication, critical operations risk management, access control, and surveillance.

As you start to look into the IPv6 integration process, you will need to look at what is in place in the network and then assess capabilities. The assessment process is about discovering capabilities of the existing equipment, services and applications. The result of the assessment process will give you an idea of what has to be done to ensure that the desired IPv6 features are supported.
A good starting point for the assessment phase is to analyze your infrastructure for basic IPv6 services. Can I configure an IPv6 address on the device? Does it support neighbor discovery and ICMPv6? The question you are trying to answer is “What are the minimum features I absolutely need to get IPv6 up and running?”
