Lenovo Flex System Fabric CN4093 10Gb Converged Scalable Switch

The CN4093 is a converged, scalable switch that supports 10 Gb/40 Gb Ethernet, or 4 Gb/8 Gb Fibre Channel (FC), or both. The flexible, reliable, and high-performance features of this switch are designed to meet the demands of today's converged environments.

The base model of this scalable switch provides fourteen 10 Gb internal ports, two SFP+ external ports, and six external Omni Ports. With the optional licensing for pay-as-you-grow scalability, you easily and cost-effectively can scale this switch to support up to forty two 10 Gb internal ports, two SFP+ external ports, two QSFP+ external ports, plus 12 external Omni Ports. This converged switch provides industry-leading performance to support traffic growth and increased requirements for virtualized workloads.

Additional capabilities and features of this converged scalable switch include the following:

Features on Demand upgrades are available for the base configurations (fourteen 10 Gb internal ports, two SFP+ external ports, and six external Omni Ports) as follows:
- Upgrade 1 turns on an additional fourteen 10 Gb internal ports and two QSFP+ external ports
- Upgrade 2 turns on an additional fourteen 10 Gb internal ports and six external Omni Ports
Converged Enhanced Ethernet (CEE) and Fibre Channel over Ethernet (FCoE) support
L2/L3 switching, CEE/FCoE, FCoE/FC with FC gateway, and FC fabric services support
Full fabric FC services such as name server and hardware-based zoning support
Up to 42 internal 10 Gb FCoE ports that support Data Control Block (DCB) protocols and FCoE FIP snooping
Up to 22 external ports that are arranged as two QSFP+, two SFP+, 12 Omni Ports (each Omni Port is capable of running in 10 Gb Ethernet mode or in 4 Gb/8 Gb Fibre Channel mode with autonegotiation)
CEE/FCoE support for all of the Ethernet ports (including the Omni Ports when they are in Ethernet mode)
FCoE/FC software and hardware to enable input/output consolidation at the server, connectivity to a FC storage area network (SAN), and end-to-end FCoE connections
