Aurora is the second largest city in Illinois, and its municipal government employees are spread across 52 different buildings. This means that the ability to collaborate with these dispersed locations is extremely important – our goal is to ensure that city employees can provide the highest level of service to our residents.
Our problem, historically, was that the city was using a mix of networking equipment from a host of different providers, making our infrastructure difficult to manage and use. This weak network prevented us from using distance-bridging technologies such as video conferencing, and it limited employee access to computer applications such as email, payroll and purchasing
To tackle these network inefficiencies, my team and I began to look at ways to use advanced fiber optics to replace our aging copper network. But we were relatively new to fiber optic technology, and our city needed a partner that could provide expertise.
Enter Cisco. Not only did the Cisco team have the fiber optic capability and know-how we needed, but we were also able to collaborate on a cutting-edge approach to network systems. Together, we decided to leverage fiber networks using an advanced color optic system, which increases network reliability and performance.
By installing Cisco technologies that optimize fiber based on light color, our city was able to run multiple networks over the same strands. To our satisfaction, we were then able to stretch the network for more coverage while still retaining high availability.

Last week, here, I started my 2 part blog on some of the top SAN design and deployment challenges we see. As I mentioned, I put this together with help from my SAN expert colleagues, Barbara Ledda and Wolfgang Lang. We are all part of the Cisco Services professional services team, where we experience first-hand the challenges of adopting new technologies including SAN.
Last week, we discussed the following challenges:
#1 Don’t assume that your server multi-pathing software is installed or working, or even licensed, or installed but never used/tested by your server team!
#2 Tendency to significantly over-estimate utilization on the SAN network.
Lets’ now discuss our challenges #3 – #5, which will discuss interoperability, expertise and architectural details respectively. Architectural details as it turns out is a key concern of some of you reading Part 1 of this blog – a few questions came in and you can view the discussion here (and thanks to my colleagues Venkat Kirishnamurthyi and Jing Luo for contributing to this discussion). With this in mind, you may find the Cisco MDS architecture discussion video here also useful.

Look after your SAN experts!
One of the aspects I really enjoy about my job is that I get to learn from some of the world’s top network and data center design engineers, and I get to hear about technology adoption challenges across the world. If there is a complex network or data center design being worked by our customers, if our customers are under time pressure, or if our customers are facing key business or technical challenges, Cisco Services’ consultants are often called in to help. Globally then, they experience first hand the challenges of deploying advanced technologies. In this blog, in the same spirit as my OpenStack Deployment Challenges blog, I’d like to share their experiences on some of the most common challenges and misconceptions faced by our customers when building Storage Area Networks (SAN). I’ll publish this in 2 parts – so look out for the concluding part next week.
Before continuing, I’d like to thank two of our SAN expert consultants, Barbara Ledda and Wolfgang Lang, for sharing their experiences and challenges.

Yesterday, over 25,000 Cisco customers, employees, and executives helped kick off Cisco Live US 2015 in San Diego, California, attending everything from John Chambers’ final keynote to the World of Solutions in the massive San Diego Convention Center. The venue, which measures over a quarter mile from end to end, features a public, secure wireless network for attendees to access from any room in the building.
Because of this network, they can tweet, post Facebook statuses, and share their favorite pictures on Instagram throughout the week, all without worrying about a faulty Internet connection. But who is keeping that network running, and who helped set it up?
As part of the Cisco Networking Academy Dream Team, students are building the skills they’ll need to thrive in the connected economy.
The Cisco Networking Academy Dream Team! As part of the Dream Team, 30 Networking Academy students have been working side-by-side with the Cisco IT team to maintain the event’s massive networks and develop the hands-on skills they’ll need to thrive in the connected economy.
Each year, more than 160,000 students in the United States and Canada enroll in Cisco Networking Academy courses, where they develop IT know-how and valuable problem-solving skills in preparation for jobs in the IT field. Of those thousands of candidates, 10 North American students are selected to participate, and another 20 local students join them to provide additional support.

Cisco Intercloud Services and Why the Network Matters
I’d like to open by restating a position on Cloud: Cloud is only in its very infancy in terms of adoption. Despite all the hype in market, largely created by the marketing of the over-the-top service providers, most of global IT spending is in the non-Cloud space. (somebody will have a stat on this but I heard it is below 10%).
So why do you think this is?
