Imagine if you could increase the capacity of your customers’ networks by up to 50%, increase the flexibility of their networks and extend the life of their core architectures. Think your customers would be interested? Well, now you can offer your customers these benefits with Dell Force10 data center switches equipped with Virtual Link Trunking or VLT.

 Traditional data centers are burdened with complex multi-tiered network architectures governed by inefficient and high-overhead protocols such as the Spanning Tree Protocol (STP). Originally, STP was designed to prevent network loops but the massive growth of virtualization and the increased demands of cloud computing have rendered STP impractical.  The rapid adoption of virtualization, cloud computing services, and distributed computing platforms such as Hadoop have contributed to thinking about alternative network architectures without the inherent limitations present with STP. While a good solution at the time, that technology is over 25 years old and there are now better ways to increase network capacity.

VLT eliminates the need for STP by increasing the intelligence of network forwarding devices, providing a non-blocking high performance network. View this video for an overview of how the VLT system works to create spine leaf architectures. For a detailed technical discussion of how Dell Force10 switches with VLT can eliminate blocked ports and enhance system capacity, check out this blog by Humair Ahmed.
