Now that we covered how LISP Routing works in Part 1 and Part 2 of this series, let dig into some of the things you can do with it. I would suggest you go back and read the first two posts if you are new to LISP since I am not going to cover that material again. So, lets look at three of the most popular use cases: 1) VM mobility, 2) IPv6 migration, and 3) smarter multi-homing. I am going to cover the generic use cases, then wrap with some real-world customer use cases.
Since it seems to be the hottest topic, let start with the mobility solution. From a networking perspective, there are a couple of things that are important with a live migration (ex. VMotion): we want to try and preserve TCP sessions (note: this does not mean “packets don’t get dropped”) and we want to maintain optimal routing (note to server folks: you too care about these things). We would also like global mobility—basically the server admin should be able to move her VM wherever she want and not be constrained by IP addressing considerations.
Let’s build on the scenario we have been using in the prior posts, where we have a host 192.168.1.12 is chatting with a VM 172.16.4.7. Assume that we have gone through the whole map-request/map-reply process, so we have something that looks like this:

SAP announces support for Virtualized SAP HANA for non-productive platforms at SAP Sapphire/TechEd Madrid
On the final day of TechEd in Madrid, SAP announced that they will be supporting virtualization for Non-Productive SAP HANA systems. No other details were given surrounding this announcement, but this is a significant departure from their previous position as it related to SAP HANA. This should be good news for Cisco given that the Cisco UCS server platform was built from the ground up to host applications in a virtualized manner. As we work with VCE, EMC, and NetApp this will only enhance our position in the SAP HANA space
Cisco had an excellent presence at the event. There were almost 700 visitors to our booth as we had on display, FlexPod from NetApp, VBlock from VCE and IT Process Automation. In addition we had as many visitors to the SAP HANA Test Drive area where Cisco had the C460 SAP HANA certified platform.
One area that got quite a bit of attention was the SAP Precision Retail mobility application on the Cisco platform. I attended two sessions that were well attended by attendees at the conference. There were at least 40 to 50 attendees at each session. In addition, the application was on display in the SAP Mobility area. Cisco is the only hardware vendor that SAP has worked with on this particular application and will be actively selling this application as part of their portfolio.
Michael Missbach, who manages Cisco’s SAP competency center in Walldorf Germany, was the leader in two Microforums on Tuesday and third speaking session on Wednesday. The first was SAP on the Cloud and the second was a Microforum with TUI Travel’s (HotelBeds) CIO Mr. Garcia. Mr. Garcia was able to discuss his installation of SAP on Cisco UCS as well as his use of SAP HANA on the Certified Cisco UCS server platform and how this architecture design has saved him approximately 150,000 Euros a year.

A truly “Better Together” story is the pairing of two strong management utilities – Cisco UCS Manager’s PowerTool offering with Microsoft’s PowerShell solution. Together they afford UCS System Administrators the ability to quickly automate and customize a multitude of management tasks resulting increased efficiency and quality utilization of IT resources and staff.
PowerTool is a Microsoft PowerShell module which helps automate all aspects of Cisco UCS management including server, network, storage and hypervisor management. A new PowerTool Quick Guide has been developed that can help jumpstart your learning and use of PowerTool with PowerShell. Available from Cisco’s Developer Network Community, http://developer.cisco.com, the document can be downloaded here.
PowerTool incorporated with use of Cisco’s UCS Manager and Microsoft’s System Center portfolio can help speed your Microsoft oriented deployments be they FlexPod (Cisco + NetApp) or VSPEX (Cisco + EMC) infrastructure based or platform focused on Windows Server 2012, Exchange 2010, or SQL Server 2012.
Feel free to download the Quick Start Guide and start exploring the power of PowerTool for your Microsoft datacenter environments. To learn more about Microsoft on UCS, please visit www.cisco.com/go/microsoft.

Is your network ready to help you transform and be the strategic partner that you can be? Let’s face it… Today’s data centers are challenged with siloed resources and facilities… Limited scalability… Poor resource utilization… Growing complexity…Perhaps the biggest challenge is time. When 80% of your resources are dedicated to “keeping the lights on” and managing all what you have, there is very little time left for innovation that benefits the business.
And the reality is that the role of IT has to change – from a cost center to a business strategic partner! Why? Because there are increasing demands on IT to help your business differentiate in order to survive and grow in these rough economic conditions. And let’s not forget that the increasing cost pressures, technology changes, and the advent of game-changers like cloud are forcing IT executives to look at how to deliver IT differently.
These growing demands put even more pressure on the shoulders of IT especially given the current state of your Data Centers. The data center network sits at the core of IT and is key to how IT can deliver services and provide value back to the business.
So what do you do? The good news is that …
