The Cisco Catalyst Blade Switch 3120 series represent the next generation networking solution for blade server environments. With the Cisco Catalyst Blade Switch 3120 series switches, HP and Cisco introduce a technology unique to blade server enclosures that allows multiple switches to act as a single entity. This switch stacking technology takes the individual physical switches within a rack and treats them as one logical switch. This innovation is the foundation of the switches' ability to simplify operations and management. Built on Cisco's proven hardware and IOS software, the Cisco Catalyst 3120 is engineered with unique technologies specifically designed to meet the rigors of the blade server infrastructure. Both switches deliver scalable, high-performance, highly resilient connectivity while supporting ongoing data center initiatives to reduce server infrastructure complexity, management and TCO.
