Advanced-level network services are a necessity for a scalable virtualized data center and a key to cloud service delivery. These services provide application acceleration and server load balancing to improve user productivity, and ensure optimal resource utilization, and they monitor quality of service. They also provide security services that can isolate applications and resources in logical zones in virtualized data centers and cloud environments to ensure regulatory compliance and reduce risk of data breaches.
While enterprises have been adopting server virtualization and cloud computing in order to realize the benefits of reduced server sprawl, reduced operating costs, and greater levels of application availability, they are doing so while struggling with inflexibility in the underlying network. Deploying advanced-level network services in a virtualized data center environment is challenging. It has been done using dedicated hardware in static network topologies. This does not provide the flexibility to support virtualized workloads, and as a result organizations are challenged to support on-demand virtual machine (VM) provisioning, workload mobility, and public or private cloud deployments. This limits organizations’ ability to efficiently deploy new applications, increases operational costs, and acts as a roadblock to adoption of virtualization and cloud computing.

Remember the days when virtualization was the new bright shiny object that everyone in IT (and the business) was interested in? VMware was just beginning to become a household name in IT shops. Many IT folks were both excited by this, and somewhat suspicious of implementing multiple VMs on a physical server. Ultimately, VMware and other virtualization vendors proved out that the concept worked well and was very compelling from an agility and cost perspective. So the teams went marching off and virtualized R&D, test, and some production applications. The results were very positive and the era of virtualization was born. Years have gone by and users have experienced all the benefits while at the same time experiencing a new set of issues and complexity that required a new model for IT.

Before I get into any thoughts or observations from PEX2011, I want to say THANK YOU to all the Cisco partners that attended our bootcamp on Monday. It was an all-day event, the day after the Super Bowl, and you turned out in force throughout the day. The bootcamp Q&A sessions and subsequent discussions at the Appreciation Party and within our booth were very insightful. Keep giving us feedback on how we can help drive your business into new opportunities in 2011.
We covered a variety of topics (UCS+VMware, Private Cloud, Nexus 1000v, VDI, VXI and Virtualized Multi-Tenant network design) and we’ll work on getting many of those presentations posted online soon.
Within the event, several key themes were prominent throughout the week: Read More »

Here we go again.
I’ve put it off, and put it off, and put it off, because every time I think about writing a piece about FCoE and TRILL I think to myself, “Okay, is this really something that enough people are going to care about to make a difference?” And then one day someone pipes up and brings up TRILL again, and thus the cycle begins anew.
I wonder if it’s related to the new zodiac signs or something.
Because I’m a person who likes to think in visual pictures, I’m going to include some pretty pictures here to help make sure I don’t miss anything along the way. I’ll also try to avoid some of the technical jargon and make it more approachable. Sometimes ya just gotta bring things back to basics. Read More »
