The Software Defined Data Center

DataCenterVirtualizationThe Software Defined Data Center: That was pretty much the biggest takeaway from this year’s VMworld in San Francisco. VMware made announcements about the new vSAN that will be coming out soon to enhance software defined storage and about the NSX platform that addresses one of the final hurdles on the path to finally having a completely software defined datacenter, network virtualization. There have been plenty of write-ups on these topics, including one very good post from one of my colleges, Bernd Harzog. I am not going to go into any details on those announcements except to say that VMware is expanding and putting themselves in a good position to be the center of the virtual universe. I believe that it will take some time for software defined networking to really take off. My gut is telling me that it will be a slower process at first, just like the adoption of server virtualization, but when it does really take off, I believe the end result will have the potential to have just as great or even a greater legacy than server virtualization has.

What Happened to Software Defined Networking?

DataCenterVirtualizationWhat happened to Software Defined Networking? A while back I wrote a post where I thought 2012 would be the year for Software Defined Network (SDN), and I am really surprised that this technology has not gained greater ground. Now that we are halfway through 2013, I find myself still waiting for adoption of this technology to really take off. With investments from  companies like Cisco, IBM, Alcatel, Juniper Networks, Broadcom, Citrix, Dell, Google, HP, Intel, NEC, and Verizon, all of which have current SDN initiatives, SDN will assume a role in IT infrastructure at some point. It just seems like it is going to take a little while longer to catch on. Continue reading What Happened to Software Defined Networking?

News: Oracle Buys Xsigo Systems

Coming on the heels of VMware’s acquisition of Nicira, Oracle announced today that it is acquiring network virtualization vendor Xsigo Systems for an undisclosed amount. So now two shoes have dropped in the question of how networks will be designed and operated in the future (perhaps the entity in question is an octopus, and we have six shoes to go). Clearly the notion of software defined networks has legs and clearly VMware is not the only company who sees this.

The Oracle Announcement

Oracle Buys Xsigo

Extends Oracle’s Virtualization Capabilities with Leading Software-Defined Networking Technology for Cloud Environments

  • Oracle today announced that it has entered into an agreement to acquire Xsigo Systems, a leading provider of network virtualization technology.
  • Xsigo’s software-defined networking technology simplifies cloud infrastructure and operations by allowing customers to dynamically and flexibly connect any server to any network and storage, resulting in increased asset utilization and application performance while reducing cost.
  • The company’s products have been deployed at hundreds of enterprise customers including British Telecom, eBay, Softbank and Verizon.
  • The combination of Xsigo for network virtualization and Oracle VM for server virtualization is expected to deliver a complete set of virtualization capabilities for cloud environments.

Terms of the agreement were not disclosed. More information on this announcement can be found at oracle.com/xsigo.

Supporting Quotes

  • “The proliferation of virtualized servers in the last few years has made the virtualization of the supporting network connections essential,” said John Fowler, Oracle Executive Vice President of Systems. “With Xsigo, customers can reduce the complexity and simplify management of their clouds by delivering compute, storage and network resources that can be dynamically reallocated on-demand.”
  • “Customers are focused on reducing costs and improving utilization of their network,” said Lloyd Carney, Xsigo CEO. “Virtualization of these resources allows customers to scale compute and storage for their public and private clouds while matching network capacity as demand dictates.”

What Does This Mean?

The most disconcerting statement in the release is the part about the “combination of Xsigo and Oracle VM”. This means that Oracle is continuing to play its “vertically integrated solution stack” game, which is in direct contrast to the horizontally layered strategies that VMware, Microsoft, Red Hat, Citrix, the CloudStack community, and the OpenStack community are all pursuing. While this might be very appealing to a customer that is 100% or nearly 100% Oracle, the notion of jamming Oracle VM down the throat of a customer in order for them to get Xsigo is just another example of the foolishness of Oracle’s closed, proprietary and arrogant approach. This could not be more at odds with VMware’s notion of the Software Defined Data Center which is completely open with respect to the hardware layers underneath it and the workloads that run on it.
