6500 Series Switches sets a new
standard for IT managers to build resilient, stateful, highly available networks while optimizing
network resource usage. VSS will play a major role in data center server access as well as
campus and data center distribution/core layer designs.
Challenge
Traditional campus and data center networks are designed with high availability in mind. The
primary aspect of high availability is to have redundant hardware components—chassis,
supervisors, modules, and links—and redundant protocols—Spanning Tree Protocol, gateway
redundancy protocol, and routing. Although this model has worked to a satisfying degree over the
years, today’s campus and data center operators are facing increasing challenges in managing
high numbers of devices and helping ensure deterministic failover times in increasingly complex
networks with varied types of new applications, business processes, and requirements. With these
new applications such as video comes the demand for more bandwidth. However, most
companies’ IT budget is not increasing at the same rate, and so IT managers are in a dilemma to
satisfy the new requirements.
Business Benefits
Cisco is introducing an innovative technology for the Cisco Catalyst 6500 Series Switches called
the Virtual Switching System 1440 (VSS 1440). VSS technology effectively addresses the
challenges faced by today’s IT manager by simplifying the existing network and leveraging past
investments.
VSS technology provides the following benefits:
●
VSS simplifies network complexity and management overhead by 50 percent, thus
increasing operational efficiency and lowering operating expenses (OpEx).
●
VSS provides deterministic sub-200-ms stateful convergence, resulting in no disruption to
application or business.
●
VSS maximizes the available bandwidth in the already installed network infrastructure,
increasing return on investment (ROI) and reducing additional capital expenditures (CapEx)
to add capacity.
Solution: Virtual Switching System 1440 Technology Overview
The VSS 1440 is a feature on the Cisco Catalyst 6500 Series Switches that effectively allows the
clustering of two physical chassis into a single logically managed entity. Figure 1 provides a
