The uptake in data center and server virtualization requires that IT rethink their data center networks.  Virtualization requires a new approach  - and perhaps a new vendor choice.

Network optimization is a key issue when it comes to virtualization.  Why? Because virtualization increases server utilization, which in turn increases traffic - creating I/O congestion from the edge devices all the way into the data center.  Within the data center, network demand is geometrically increased as virtualized workloads are distributed across multiple servers. 

Vendors are targeting the network needs of virtualized data centers with a variety of solutions.  These divergent approaches to delivering next generation data center networks can be confusing – and proprietary.  Consequently, choosing the right virtual vendor can be more difficult than ever. 

It’s unclear today which vendor will dominate the virtualized data center network market. What is clear is that IT needs to be smart when selecting next generation technologies:

1. Integrated is better than standalone. Virtualization requires tight integration and scalability between the network and the virtual server architecture.  Buying separate products and knitting them together may be lower cost up front – but will most likely by higher cost in the longer term thanks to the ongoing management overhead to continually tune the products to work together.  Not to mention the finger pointing.  Solutions that are designed to work together from the network through the virtual server architecture will improve initial deployment and ongoing management (and productivity).


2. Avoid vendor lock-in and costly upgrades. As with previous technology advances, proprietary approaches will rule for the first phase of solutions. Each vendor will offer their approach – and over time, will converge to offer open solutions (or integration APIs) to achieve interoperability.  If history repeats itself – market leaders will set the open standards – meaning that buying from an unknown vendor may leave you stranded in your own locked-in world.


3. Double check that roadmap. Ask to see any vendor’s roadmap – as well as for references on their current deployments.  Don’t buy anything without customer evidence of its value.   Ask your network experts to review comprehensive technology roadmaps with each vendor to be sure that vendor is heading in the direction you want to go.

Most importantly – choose a vendor who understands your requirements, your business and can show you successful deployments in customers who mirror your own data center and infrastructure requirements.
