Lenovo Flex System Fabric EN4093R 10Gb Scalable SwitchProduct GuideThe Lenovo® Flex System Fabric EN4093R 10Gb Scalable Switch provides unmatched scalability, port flexibility, and performance. The switch also delivers innovations to help address several networking concerns today and provides capabilities that help you prepare for the future.This switch can support up to 64x 10 Gb Ethernet connections while offering Layer 2/3 switching, in addition to OpenFlow and "easy connect" modes. It installs within the I/O module bays of the Flex System™ Enterprise Chassis. This switch can help clients migrate to a 10 Gb or 40 Gb Ethernet infrastructure, offers cloud-ready virtualization features (such as Virtual Fabric and VMready®), and is Software Defined Network (SDN) ready. The EN4093R 10Gb Scalable Switch is shown in the following figure.Figure 1. Lenovo Flex System Fabric EN4093R 10Gb Scalable SwitchDid you know?The base switch configuration comes standard with 24x 10 GbE port licenses that can be assigned to internal connections or external SFP+ or QSFP+ ports with flexible port mapping. For example, this feature allows you to trade off four 10 GbE ports for one 40 GbE port (or vice versa) or trade off one external 10 GbE SFP+ port for one internal 10 GbE port (or vice versa). You then have the flexibility of turning on more ports when you need them by using Lenovo's Features on Demand upgrade licensing capabilities that provide “pay as you grow” scalability without the need to buy more hardware.The EN4093R is cloud ready with support for VM aware networking and advanced NIC virtualization technologies, such as Unified Fabric Port (UFP). In addition, the switch offers different operational modes (from "easy connect" transparent networking connectivity to Layer 3 functionality) to satisfy diverse client networking requirements.The EN4093R switch is SDN-ready with support for OpenFlow. OpenFlow is the protocol that enables the network administrator to easily configure and manage virtual networks that control traffic on a "per-flow" basis. OpenFlow creates multiple independent virtual networks and related policies without dealing with the complexities of the underlying physical network and protocols.With support for Converged Enhanced Ethernet (CEE), the EN4093R can be used as an FCoE transit device and is ideal for network-attached storage (NAS) and iSCSI environments.Click here to check for updatesFigure 2.

Location of the I/O bays in the Flex System Enterprise ChassisThe EN4093R switches can be installed in bays 1, 2, 3, and 4 of the Enterprise chassis. A supported adapter must be installed in the corresponding slot of the compute node. Each adapter can use up to four lanes to connect to the respective I/O module bay. The EN4093R can use up to three of the four lanes.In compute nodes that have an integrated dual-port 10 GbE network interface controller (NIC), NIC ports are routed to bays 1 and 2 with a specialized periscope connector, and the adapter is not required. However, the periscope connector can be replaced with the adapter when needed. In such a case, integrated NIC is disabled. With flexible port mapping, there is no need to buy switch upgrades for 4-port and 8-port adapters if the total number of port licenses on the switch does not exceed the number of external (upstream network ports) and internal (compute node network ports) connections that are used.The following table shows compatibility information for the EN4093R and Flex System chassis.Table 7. Flex System chassis compatibilityThe midplane connections between the adapters that are installed in the compute nodes to the I/O module bays in the chassis are listed in the following table. Half-wide compute nodes support up to two adapters, and full-wide compute nodes support up to four adapters.Table 8.
