Server Virtualization requires new thinking for architecting the Data Center Network
Aug 31, 2010
Server virtualization can dramatically reduce costs, increase resource utilization, and improve IT responsiveness without requiring significant changes to the server infrastructure. No wonder it’s the most popular and widely deployed virtualization technology in the data center.
However, server virtualization also requires customers to think differently about how to build their data center infrastructures. First, server virtualization breaks the “one server, one OS, one application” rule that has driven data center design; instead, each server hosts multiple virtual machines (VMs), each with different operating systems and applications. Managing these VMs—a concept known as multi-tenancy—requires highly sophisticated traffic isolation, policy management, and network configuration capabilities. Second, server virtualization disrupts the relationship between applications, operating systems and physical servers; thanks to VM mobility, applications and their associated OSs no longer must be persistently bound to a specific physical server. Furthermore, hypervisors now come with software-based virtual switches that reside inside servers, where they create “virtual networks;” maintaining a consistent view of both physical and virtual networks is a tremendous challenge.
What’s the answer?
Juniper’s web-based Junos® Space Virtual Control application enables consistent configuration, visibility and automated orchestration between virtual and physical networks.
Residing on the Juniper Networks Junos Space orchestration platform the Virtual Control application enables end-to-end network topology, configuration and policy management from a single pane of glass, dramatically simplifying data center management and reducing TCO by providing network-wide operational consistency and visibility.
Because network managers often lack access to the virtual switch and typically require multiple tools to manage physical and virtual networks, “it naturally creates obstacles to service creation and streamlined operations," says Zeus Kerravala, distinguished research fellow with Yankee Group. "With Junos Space as a platform, combined with Juniper's new automation applications, administrators can quickly improve data center performance, while lowering the overall complexity and cost of implementing and managing virtual environments.”
"Customers want an open environment with choice and flexibility rather than proprietary lock-in," adds Parag Patel, vice president, Global Strategic Alliances, VMware. "Juniper shares this vision and is now offering a solution that provides collaborative management between VMware vSphere™ and Junos Space. The Juniper Virtual Control application takes advantage of the VMware vNetwork Distributed switch to achieve seamless orchestration across both physical and virtual network elements. The result is a faster and simpler operations environment that reduces human errors and saves time and money."
