Cisco Catalyst Switch Modules 3110G and 3110X for IBM BladeCenter
IBM BladeCenter at-a-glance guide
Built upon Cisco's market-leading hardware and IOS software, the switches are designed to deliver scalable, high performance, highly resilient connectivity while reducing server infrastructure complexity.
Figure 1. Cisco Catalyst Switch Module 3110G (left) and 3110X (right). The 3110X has a separate X2 transceiver module installed.
Did you know?
The Cisco Catalyst Switch Module 3110 has a unique technology called Virtual Blade Switch (VBS). Much like server virtualization technology, this switch virtualization technology treats the individual physical switches within a rack as a single logical switch. As with server virtualization technology, this innovation allows the switches to deliver better utilization, increased performance, and greater resilience while simplifying operations and management.
