Organizations of all types continue to invest in IT to develop new revenue opportunities, reduce costs, and improve service levels. However, this continuing investment is exacerbating facilities concerns for organizations, especially in the areas of power, cooling, rack space, and cable management. These challenges are especially salient in the area of server infrastructure, where the rapid growth of application use has lead to significant server sprawl in the data center.

• By significantly simplifying data center design and operations, the VBS reduces infrastructure complexity, improves network resiliency, and increases the operational manageability of the blade-switching environment. For example, the VBS appears as a single network device, so the network topology is greatly simplified, enabling quicker deployment, a more robust network, and faster troubleshooting and problem resolution.
• By providing up to160 Gbps upstream, the VBS provides exceptional performance. At the same time, the VBS can double the bandwidth available to a server. These features give server administrators significant flexibility in supporting the performance requirements of their severs and applications.
• The VBS makes extensive use of link virtualization for both upstream connectivity and server connectivity, increasing both available bandwidth and redundancy. Note that the VBS can recover from a physical link failure without having to reconverge the network, helping eliminate session drops.
• The VBS uses the same Cisco IOS Software interface, MIBs, and management tools as the rest of the Cisco Catalyst products, simplifying operations and management by the network operations team and helping ensure that attached servers can fully participate in end-to-end network services such as quality of service (QoS) and security policies, helpful in maintaining regulatory compliance.
• The Cisco Catalyst Blade Switch 3100 Series allows mixing and matching of Gigabit Ethernet and 10 Gigabit Ethernet switches, providing customers with a cost-effective migration path. Switch capacity can be incrementally upgraded as server needs demand.
