The Enterprise Strategy Group (ESG) has released this week a whitepaper and companion video looking at virtual network overlays and their use in multi-tenant environments. This comes on the heels of the ESG research brief on Cisco’s recently announced Cisco ONE set of network programming interfaces which includes Nexus 1000V-based virtual overlays.
ESG points out that virtual network overlays are important to building out multi-tenant environments like private and hybrid clouds, as well as overcoming scalability issues in those environments that have traditionally been based on VLANs. As ESG notes, and as Cisco mentioned in it’s ONE announcement, programmability of the virtual networks is what really separates them from classic overlays based on MPLS or GRE tunnels. The Nexus 1000V will achieve this programmability capability by SDN API’s such as OpenStack on top of the Nexus 1000V virtual supervisor module.

Feeling frustrated among all this chatter about Cloud? Want to implement a cloud solution quickly for your business, but don’t know where to start? I can help you understand how to maximize your benefits during the process of adopting a cloud solution. It’s as simple as 3 C’s: confine, clover, and cost.
Today, I will focus on the first “C”—Confine.
Before you can determine what cloud strategy you want to implement, you need to narrow down or “confine” the business problem you want to solve with Cloud. Once you have confined the problem, you can begin your roadmap for success with clear goals and expectations.
But how do you confine the problem? I suggest you take a good look at the market forces that are pushing you to consider cloud. Internally, it may be cost efficiency: reducing IT investment or managing staffing costs. Externally, the forces could be government regulations or competitive differentiations that are leading you to consider a cloud solution.

Whether we’re at home or in the office, the truth is that all customers want choices. No one wants to be told they can only use one type of DVD player because it is the only one compatible with their television, and the same holds true in the enterprise. In talking with our customers, we know that they want best-in-breed products. They want to know that whatever product they choose, it will work together seamlessly with their legacy devices to deliver uninterrupted access to the data center. That doesn’t seem unreasonable, does it?
I think that having choices is important – after all, who knows your data center better than you do? So, in keeping with my focus of listening to our customers, I am excited to share with you that just like our Fabric Extender (FEX) collaboration last year with HP, we have most recently brought the FEX technology to the Fujitsu PRIMERGY blade chassis, giving joint customers an opportunity to further simplify data center access operations and improve productivity. The PRIMERGY Ethernet FEX, also know as the Cisco Nexus B22F, extends the Cisco Unified Fabric into the Fujitsu PRIMERGY Blade Chassis and offers operational simplicity at scale with a single point of management and policy enforcement.

Recently while speaking with a group of Cisco Systems Engineers about their respective Microsoft Exchange 2010 migrations the group commented on the range of engagement sizes – in terms of individual mailboxes supported – that they had implemented during the past year or so. What we learned during this discussion is the extreme scalable nature of UCS when it comes to Exchange as engagements of up to 250,000 mailboxes were successfully handled. Additionally UCS’s virtualization capabilities – with either Hyper-V or VMware – were seen adding to the efficiency of these larger scale engagements.
If you would like to learn more about UCS and Exchange, please register to listen to our upcoming August 1st webinar – Taking the Sting out of Exchange 2010 Migrations. Also, please visit www.cisco.com/go/microsoft to learn more on Cisco UCS and how it is an optimal server platform for your Microsoft workloads.

I am happy to announce another Virtual Symposium, this time on the topic of virtual machine networking. We will be holding it on July 25th from 9am to 10am Pacifc Time.
Beyond our usual panel of Greg Ferro, Steven Foskett, Ivan Pepelnjak and yours truly, we will be joined on the panel by Marko Milivojevic (@icemarkom), David Davis (@davidmdavis) and perhaps a couple of other folks.
We have settled on the 60 min format. The panel will share some initial thoughts, but we will devote most of the time to answering questions from the audience, either through the WebEx Q&A tool or via the #VirtSyn tag.
To register, go here.
See you there.
