New Reality: Virtualization Specialists May Need to Know More about Networks
Virtualization means making a “virtual” version of something such as a hardware platform or operating system. Recently, there has been increasing use of virtualization in the computer sector – as well as more use of the specialists who businesses can rely on for their expertise. But it has become increasingly the case, too, that more of these IT pros need specialized knowledge about networks.
Looking back, there was what was Chris Wahl describes in Biz Tech Magazine as a “bottom-up approach” to virtualization. It led to thorough testing before implementation, but networking and storage was left “in the hands of the server team,” he said. Generally, that does not pose problems since VMware’s vSphere and other hypervisors can simplify or hide network topology. In fact, with vSphere servers, basic virtualization needs someone with just a little networking knowledge. But the network situation can change, given the increasing use of private-cloud models in enterprise data centers, Wahl warns, and with VMware’s vCloud Director, it may be up to the server team to ensure network components are configured the right way and working properly.
“The networking portion is the hardest part to grasp, digest and master for virtualization specialists — as it hasn’t always been a key component in their toolkit — while at the same time being the most crucial for a successful implementation,” Wahl said. “This gap in their knowledge base needs to be filled.”
He suggests getting more familiar with network architecture and design at an organization by asking those who know about it. Consider getting routing and switching certification. Cisco Systems (News - Alert) provides an associate level certification, the CCNA, which encompasses basic networking. Juniper has the JNCIA. And many vendors have labs that can be used by partners and customers for free. Or rack rentals offer access to gear. Some businesses may have old networking gear in a lab. There are also simulators like Graphical Network Simulator (GNS3) or kits for Cisco or Juniper.
The knowledge gained can go a long way toward boosting your career.

As the need to balance current and future IT requirements against resource consumption becomes more urgent, the data center industry increasingly views capacity planning as a way of achieving a critical component to planning a new build or retrofit. Data center capacity planning can be a complex undertaking with far-reaching strategic and operational implications. DCD Intelligence has therefore compiled this White Paper in order to share some industry insights and lessons on the practical steps that are needed to develop a successful power and capacity planning strategy.[Read More]
Server Technology had the recent opportunity, along with other partner companies, to participate in discussions across the globe with data center IT and facility managers as part of a road show seminar: Data Center Energy and Operational Efficiency.[Read More]
The demand for more power in the computer cabinet has led many data centers to upgrade to three phase power distribution. Proper three phase power distribution has traditionally meant dividing up power up into multiple branches within the rack PDU (Power Distribution Unit). In this paper we will explore the advantages of a new, less common approach to PDU design by means of alternating each phase on a per-receptacle basis instead of a per branch basis.[Read More]
Increasing powering and cooling demands within the data center have been the topics of choice for Data Center (DC) and Facility Managers for several years now. Increased power demands are a result of the need for more compute power and higher density devices have resulted. These high density installations include stacks and stacks of servers and the trend of implementing blade servers within these server "farms." Cooling problems are a direct result of the increased power demands based on the simple fact that more power increases the demand for cooling.[Read More]
