Testing 10G Data Center Switches: Scaling 10 Times Higher

If there’s one overarching conclusion I’ve drawn from three months of testing 10-gigabit top-of-rack data center switches, it’s that “switch” and “data center switch” are very different beasts. Understanding the latter means testing new features like virtualization support and storage/data network convergence, while also driving unicast and multicast scalability benchmarking to new heights. In a project recently published in Network World, we compared switches from six vendors, eac...

Testing Data Center Virtualization: Are you asking the right questions?

Data centers today are larger, faster and more complex than ever. New technologies such as virtualization, Fibre Channel over Ethernet and 40/100 Gigabit Ethernet aim to help organizations move multiple traffic types – data, storage, video, and voice – onto a single, converged core. Validation of all these new technologies through testing is a crucial part of the product development and deployment process. Today, let’s look at testing virtualization. Testing virtual network de...
