Amid all the noise of last week’s VMworld event, data center specialist Brocade augmented its vision for software defined networks (SDN) by announcing support for VXLAN to its ADX application delivery controllers (ADCs). To date, all of the VXLAN and SDN announcements have been focused on traffic on a single network within a data center. The ADX enhancement is meant to interconnect traffic between networks. This could be a virtual-to-virtual network or virtual-to-physical network.

As far as I know, Brocade is the first vendor to address moving traffic to another network that is distinct from a particular VXLAN-based overlay network. From what I understand, Brocade chose to add this functionality to its line of ADCs versus Ethernet switches because the ADX has some unique features that switches lack, such as stateful failovers, load balancing and the ability to maintain high availability. Bringing the ADC into the mix gives Brocade a unique plan in SDNs that can extend what it does at layer 2-3 up the stack at layers 4-7.

Earlier this year, Riverbed released a product known as the “Granite Edge Virtual Server Infrastructure (VSI)” to optimize the performance of many of the applications that it’s core product, Steelhead, does not. 

For those not familiar with the differences between Steelhead and Granite, the traditional Steelhead product optimizes the performance of file-based applications, such as Word and Exchange, through a number of acceleration technologies such as compression and TCP optimization.  Granite addresses block level applications such as database and virtual machines. 

While the continued growth of Steelhead demonstrated that there were a number of “killer apps” for it, the killer application for Granite was not obvious, since there aren’t that many block storage based applications run in the data center.

This year’s VMWorld kicks off this week in San Francisco and I’m expecting the typical huge audience.  One of the reasons why VMWorld has become the premier show that is has is because virtualization itself is changing.  Virtualization used to be a tactical technology used to consolidate servers.  Have 10 servers?  Consolidate that down to one or two.  The architecture fundamentally stays the same, just fewer physical boxes. 

Virtualization today though is a much more strategic technology.  It powers the cloud, desktops are being virtualized, storage is being virtualized and data center operations are being automated.  However, being more aggressive with virtualization does bring some new risks to enterprise IT.  To understand what some of these are, ZK Research and Xangati, a cloud and management solutions provider, recently ran a survey looking at where companies were with cloud deployments, where they were going and what the challenges were for future deployments.
