Non-stop Wireless at Johns Hopkins Hospital

June 30, 2014 at 10:42 am PST

Johns Hopkins Medicine is one of the leading health-care providers in the US. The Johns Hopkins University School of Medicine is consistently ranked as one of the top Medical Schools in the US and the Johns Hopkins Hospital is consistently ranked #1 in the US for 21 years in a row! In a previous blog in 2012, we described how the Cisco Wireless LAN controller 7.5 release enables wireless networks to recover with no client re-authentication in the event of a primarily controller failure. In this blog, I will share more details about unified access deployment at the Johns Hopkins Hospital with particular focus on the High Availability design.

Patients are the focus at Johns Hopkins Hospital. Johns Hopkins uses state-of-the-art technology in their hospitals to ensure that patients get the latest advances from surgical tools, radiologic imaging suites with the best diagnostic capabilities to something as humane as sound-absorbing private rooms for each patient.

Sarasota County Schools includes 24 Elementary Schools, 9 Middle Schools, 8 High Schools and various Technical and various Special Centers. It houses about 40,000 students in about 250 buildings. The Sarasota School IT Team believes in using the best-in-class technologies to provide the optimal connected experience for students, faculty, staff and guests.

This next generation pervasive WLAN network enables students to collaborate with each other anywhere on the campus and with the teachers in the classroom. In the previous blog, we described how Bowdoin and the Pinellas County have embraced the IOS based 5760 Series controllers. In this blog, we will cover more details about the recent upgrade of the Wireless LAN Controller from the previous model WiSM to the new model 5760 and describe highlights of our conversation with xx about the WLAN deployment itself.

Cisco @ Interop – It is All about Solutions that Solve Problems

Usually at shows like Interop Las Vegas 2013, attendees wander around the show floor looking at all the new products that are coming out from vendors. Now it is always exciting to see the latest and greatest technology coming out, but very often there is so much information to consume it is difficult to envision how these new products will solve problems that IT organizations are facing today.

Cisco is taking a different approach at Interop this year. In the Cisco booth there are a number of demo stations including the traditional new product demos, ask the experts stations, trivia games and many more, but in addition there are two unique demos the “Your NOC Your Way” Demo and the Unified Access Experience Demo that take a solution perspective to addressing top IT concerns.

1. The “Your NOC Your Way” Demo

This unique demo focuses on how Cisco solutions can aid in addressing the top concerns of network operations managers. Read More »

Automate Migrating ESX Host Interfaces to Nexus 1000V

January 16, 2013 at 8:45 am PST

“We’ve tried, it can’t be automated!” I’ve heard this more times than I can keep track of and if you read my previous blog you will know that I just do not agree. I have written about automation with Linux utilities, UCS PowerTool, AutoHotKey, Excel, etc… 99.999% of operations can be automated. So when a customer tells me that something cannot be automated I usually respond with “Have you tried …?”

Here is the scenario; the customer has an automated build process for ESX hosts. At the point where the host is ready to be connected to the Nexus 1000V the process becomes manual. The customer would like to use VMWare PowerCLI to migrate the host interface but the Cmdlet to retrieve Distributed Virtual Switches, Get-VirtualSwitch, just returns the DVS objects,  there isn’t a Cmdlet to migrate the ESX vmnic interface.

Hold on a second, I know that VCenter knows about the Nexus 1000V because I see it in the interface. I know that VCenter can manipulate the Nexus 1000V because VCenter is where interface migration is done. I am fairly certain at this point that ESX interface migration from the VCenter vSwitch to the Nexus 1000V can be automated. But what to use to do it, there is no PowerCLI command like Set-ESXHostInterfaceToN1kv. This is typically where automation ends for many, sometimes you have to dive deep into the objects that the system manages and figure out what to do. Sometimes someone has already done a deep dive into something like what you are trying to do and maybe you can build off of their work.
