Network Virtualization: Solution to the Data Center Traffic Issues, Heavy Reading Says

BOSTON, March 11, 2013 /PRNewswire/ -- As the data center has progressed, it has struggled to cope with growing virtualized data traffic, and network virtualization is the answer to those problems, according to the latest report from Heavy Reading Service Provider IT Insider (www.heavyreading.com/servsoftware), a paid research service of Heavy Reading (www.heavyreading.com).

Network Virtualization Comes of Age in the Data Center examines network virtualization in the data center, focusing on the importance of network virtualization, and the technologies and protocols that support it. The report also profiles 14 leading vendors in the market.

"Server and storage virtualization technology has revolutionized the data center in recent years, consolidating physical hardware resources and optimizing CPU, RAM and hard disk capacity to help deliver maximum performance with minimum power consumption, faster provisioning and simplified management," says Martin Courtney, Analyst at Heavy Reading and author of the report. "But the underlying network that those virtualized servers and storage rely on to communicate with each other has failed to keep pace with parallel innovation efforts and data center operators supervising growing volumes of virtualized data traffic beginning to bump against the scalability, flexibility and management limitations that traditional Layer 2 and Layer 3 physical network architecture imposes on the virtual world."

The need for change has become particularly pressing in large scale data center environments that are provisioning, migrating and tearing down thousands of virtual machines every minute, Courtney says. "Network virtualization technology is clearly of most practical use in solving virtual machine scalability issues in larger data centers run by telcos, cloud service providers and Internet companies hosting high volumes of multi-tenanted virtual workloads, either in single or multiple locations," he continues. "But while the large scale requirements of big cloud service providers and search engines do not necessarily correlate to the needs of the enterprise, vendors are busy trying to convince themselves that network virtualization technology and SDN initiatives will trickle down into corporate data center environments."

Key findings of Network Virtualization Comes of Age in the Data Center include:

• Data center networks are struggling to cope with the explosive growth in virtualized data traffic.
• Cloud service delivery demands a more scalable, flexible network that is easier to manage.
• Network hardware vendors are focusing their efforts on virtual network overlays and software-defined networking.
• Virtual network overlays are built on a confusing mix of standardized and proprietary protocols and platforms.
• SPB, TRILL, LISP, ARMD, VXLAN, NVGRE, STT and MLAG all have backing from different vendors.
• The underlying technology remains immature, and the market has seen few customer deployments.
• Adoption forces changes in the way vendors design and sell L2/L3 switches.
