Lenovo Flex System EN2092 1Gb Ethernet Scalable Switch

Streamline Your Data Center

The Lenovo® Flex System™ EN2092 1Gb Ethernet Scalable Switch enables administrators to offer full Layer 2 and 3 switching and routing capability with combined 1 Gb and 10 Gb external ports in a Flex System chassis. Such consolidation simplifies the data center infrastructure and helps reduce the number of discrete devices, management consoles, and management systems while leveraging the 1 Gb Ethernet infrastructure. In addition, the next-generation switch module hardware supports IPv6 Layer 3 frame forwarding protocols. This Scalable Switch delivers cost savings with flexible port mapping and Features on Demand upgrades, efficient traffic management, increased external bandwidth, and strong Ethernet switching price/performance.

Flexibility and Scalability

The EN2092 helps clients reduce I/O costs today while providing investment protection for the future with unmatched flexibility and scalability. The flexible port-mapping1 feature offers the ability to dynamically assign ports based on need. In addition, the EN2092 supports the Feature on Demand (FoD) capability which allows clients to scale Ethernet ports as required by simply purchasing software upgrade licenses to turn on additional 1 Gb or 10 Gb Ethernet ports.

Optimized and Automated

Many organizations are looking for high performance and awareness of virtual machines (VMs) at the network level. Using innovative VMready® virtualization-aware networking technology, you can simplify virtualization management. VMready automatically discovers virtual machines and allows unique networking parameters to be configured for each virtual machine. VMready works with all major hypervisors.
