Data center network design architecture is changing to reflect growing IT trends in distributed applications and virtual computing. New computing models require a flatter network that is flexible enough to handle unpredictable traffic patterns. Find out what that means for your company in this interview with Cindy Borovick, Vice President of IDC’s Enterprise Communications and Datacenter Networks programs.

The Need to Rethink the WAN

Technological advances have evolved at an exponential rate over recent decades—we’ve seen the advent of the Internet, cloud computing, virtualization, and several other technologies. But the wide area network (WAN) technologies that are currently in use in most branch offices have changed little since the 1990s.

Business environments today are experiencing unprecedented growth and change, and IT departments are losing visibility and control. Traditional WAN technologies are a mismatch for... Read More

Optimizing Bandwidth: Why Size Doesn’t Always Matter

Network managers have to balance the need for increased speed of response and the best possible end user performance, and the need to reduce costs.

Traffic on the network expands to fill the available bandwidth, resulting in degraded performance across the most congested links. Network managers have to be able to show that a link is experiencing congestion for a significant amount of time due to legitimate business usage before they can add additional capacity. But approaches such as peak... Read More

Enterprises today need flexibility and simplicity for their current activities, but more importantly, they need a way to maintain flexibility and simplicity going forward, when business demands on applications, the network, and infrastructure are only going to increase. To better serve the business demands for information everywhere, enterprises must therefore develop new strategies for optimizing multiple kinds of networks. This white paper shows you how to build and maximize hybrid networks and... Read More

Green Server Design: Beyond Operational Energy to Sustainability

  • Source: HP
  • Written By:
  • Published:
“Green” server and datacenter design requires a focus on environmental sustainability. Prior studies have focused on operational energy consumption as a proxy for sustainability, but this metric only captures part of the environmental impact. Understanding the total impact requires examining the entire lifecycle of the system, beyond operational energy, to also include material use and manufacturing. See how one methodology can do that. Read More

NGN Control Plane Overload and its Management

Given the types of overload scenarios encountered within traditional networks, similar traffic principles requiring overload management will be required within (NGNs). What, then, are the characteristics of overload protection within real-time communications servers? And what types of overload management methods are available for optimizing server performance? Read More
