Visibility in Motion at Cisco Live Orlando

Now that Cisco Live Orlando has come and gone and we’re gearing up for VMworld, we’re seeing even more attention being paid to virtualization given the interest in software defined networks (SDN) and data centers (SDDC). So, virtualization remains hot and with around 60 percent of all applications running in virtualized environments according to some studies, we shouldn’t be surprised that there are even summer camps being offered around the subject (I’m not kidding). I feel like 2013 is the Summer of Virtualization!
That being said, it makes sense to let you know how Gigamon is continuing to address the visibility challenges being experienced by organizations utilizing virtualized environments.  On the first day of the Cisco Live World of Solutions expo we announced GigaVUE-VM 2.0. If you’re not familiar with our GigaVUE-VM, it is basically a virtual instance of one of our Visibility Fabric nodes. Because traffic between virtual machines may be switched locally, it will never traverse the physical network, rendering existing monitoring and analysis tools blind to this virtual traffic.  The GigaVUE-VM fabric node provides that packet-level visibility into the virtualized server world.
One of the dynamic things about the 2.0 update in addition to exposing inter-VM traffic flowing within a physical host and across physical hosts is that GigaVUE-VM now supports Cisco’s Nexus 1000V virtual switch as well as VMware’s vSphere Distributed Switch (VDS). GigaVUE-VM works with these virtual switches to abstract copies of the packets before intelligently filtering and forwarding the packets to the management, security, and monitoring tools that require packet-level visibility, such as application and network performance monitoring tools and intrusion detection systems.
Perhaps even more exciting is that GigaVUE-VM 2.0 has the ability to automatically reconfigure Gigamon’s Visibility FabricTM architecture and migrate monitoring policies to maintain continuous visibility when a virtual machine vMotion event occurs. Essentially, GigaVUE-VM preserves visibility into the traffic flowing between VMs even after that VM moves from one physical host to another for what we call “visibility in motion.”
What’s so significant about this function is that without the ability to automatically migrate the monitoring policies, visibility that had been configured would be lost once the vMotion occurs and would require manual reconciliation which very well could be arduous given the agile virtual infrastructures of today.
