The Cisco Catalyst Blade Switch 3120 Series Switches are specifically designed to meet the rigors of the blade server based application infrastructure & provides HP Blade System customers with the ability to stack up to nine switches into a single virtual Switch. By emulating a redundant top-of-rack switch, HP Blade System c-Class users now have an integrated switching solution from Cisco Systems that optimizes uplinks per rack, reduces the number of switches managed & decreases network complexity. Both switches also provide Cisco resiliency, advanced security & enhanced manageability to the server edge while dramatically reducing cabling requirements. The 3120G is a 1 Gb switch with the flexibility to provide both copper & fiber uplinks. The Cisco CBS3120 offers operational consistency with the rest of the industry leading Cisco Catalyst series of switches, using the familiar IOS Command Line Interface (CLI), consistent MIBs, & management tools like Cisco Works. Furthermore, this consistency with the rest of the Cisco Catalyst series ensures end-to-end network service like Qo S are consistently implemented across the network.
