Introducing OTV: New Datacenter 3.0 Technology Tackles Global Virtual Machine and Workload Mobility

February 8, 2010 - 0 Comments

Plenty of ink has been spilled on today’s technology releases from Cisco.  Most notably, Omar does a fantastic job of detailing the new technologies Cisco is bringing to market today, including Overlay Transport Virtualization and Cisco’s new 10GBase-T offerings.  I’m going to embed some video below on both, but before I do, I thought I’d take a brief moment to draw out some of the exciting ramifications of OTV.

As previously mentioned, my knowledge tends toward the compute side of the house.  OTV is very much a networking technology (in technical terms it allows you to overlay a Layer 3 network on top of a Layer 2 network) available for the Nexus 7000 datacenter switches starting today.  However, the practical implication of this technology are very much compute and virtualization relevant.  In essence, OTV easily enables full VM and workload mobility between disparate datacenters.

Already OTV is getting rave reviews from virtualization vendors, such as VMware. “Moving workloads between data centers has typically involved complex and time-consuming network design and configurations,” said Ben Matheson, senior director, global partner marketing, VMware. “VMotion can now leverage Cisco OTV to easily and cost-effectively move data center workloads across long distances, providing customers with resource flexibility and workload portability that span across geographically dispersed data centers.  This represents a significant advancement for virtualized environments by simplifying and accelerating long-distance workload migrations.”

But don’t take my word for it, here’s oodles more info on OTV:


Additionally, today we also announced new 10GBase-T products to help customers ease the transition to 10GbE networking:
