The Cisco Catalyst Blade Switch 3120 represents the next generation networking solution for blade server environments. Built upon Ciscos proven hardware & IOS software, the Cisco Catalyst 3120 is engineered with unique technologies specifically designed to meet the rigors of the blade server infrastructure. Both switches are designed to deliver scalable, high performance, highly resilient connectivity while supporting ongoing data center initiatives to reduce server infrastructure complexity, management & TCO. With the Cisco CBS 3120 series switches, HP & 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 & treats them as one logical switch. This innovation is the foundation of the switches ability to simplify operations & management. Multiple IOS upgrade options make the CBS 3120 extremely versatile. Please note: server components such as memory & power supplies must match those already installed in a server. To avoid compatibility clashes or for advice, please contact us on solutions@ebuyer.com.
