The Virtualization Practice

Virtual Networking Is Not Network Virtualization

While SPB is a very interesting protocol, my questions were about how deep into the virtual environment the protocol extends. While SPB and other networking protocols are considered by some to be network virtualization, I could not see this within the realm of the virtual network and hence, confusion reigned supreme. Depending on who is talking to each other, the same words can mean many different things. What I found amazing, still, is that most people thinks networking ends at the physical NIC within the virtualization host, and that what is inside, does not matter as much as what is outside.


The benefits of virtualizing networking and storage will be very different than were the benefits of virtualizing CPU and memory. VMware’s success to date has not come at the expense of server vendors. However VMware’s success with virtualized networking will come at the expense of Cisco. The success with virtualizing storage will come at the expense of enterprise storage vendors. By commoditizing networking and storage VMware will deliver substantial benefits to its customers, and create strained relationships with vendors who used to be partners.

CloudBolt Software has announced that version 3.5 of CloudBolt Command and Control (C2) will integrate with VMware Nicira Network Virtualization Platform (NVP). CloudBolt C2 takes advantage of the NVP virtualization API’s to programatically create complex secure networks, entirely in softwarer, and completely independent of the underlying network hardware.


In my humble opinion, 2011 was the year for storage inside the virtualization space with a lot of new storage related technologies presented at VMworld 2011. There were different technologies ranging from Tier 1 SSD storage in a box that can plug right into VMware vSphere as its own datastore, to all the software storage venders that are now virtualizing their Storage Processers. Yes, for me, 2011 was the year for storage in virtualization.
