Lenovo Flex System EN4023 10 Gb Scalable Switch

Tab navigation



The Lenovo® Flex System™ EN4023 10 Gb Scalable Switch is designed for easy integration into a Brocade Virtual Cluster Switching (VCS) environment. Brocade VCS Fabric technology simplifies network design and operations for a more automated and efficient network. This switch offers flexibility via Dynamic Ports on Demand (DPOD). You can start with a base 24-port entitlement that can be applied to any of the internal or external ports. The switch also offers external Flex Ports that can be configured as Fibre Channel or FCoE ports.

Port Flexibility

This 10 Gb Scalable Switch allows clients to configure ports based on their needs. Clients that deploy the Lenovo Flex System x222 Compute Node can configure up to 10 nodes in the chassis with four 10 Gb uplinks using just the base switch. The x222 is a double-dense server, allowing clients to connect up to 20 independent servers using just the base switch. This allows clients to effectively manage their switch port licenses for both internal and external connections.
