The 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 64 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 Lenovo Virtual Fabric and VMready®), and is Software Defined Network (SDN) ready.

To increase the number of available 10 GbE ports, clients can split out four 10 GbE ports for each 40 GbE port using QSFP+ DAC breakout cables for distances up to 5 meters. For distances up to 100 m, the 40GBASE-iSR4 QSFP+ transceivers can be used with OM3 optical MTP-to-LC break-out cables or up to 150 m with OM4 optical MTP-to-LC break-out cables. For longer distances, the 40GBASE-eSR4 transceivers can be used with OM3 optical break-out cables for distances up to 300 m or OM4 optical break-out cables for distances up to 400 m.
With the growth of virtualization and the evolution of cloud, many of today’s applications require low latency and high bandwidth performance. The EN4093R is the embedded 10 GbE switch for a compute node chassis to support sub-microsecond latency and up to 1.28 Tbps. It also delivers full line rate performance, which makes it ideal for managing dynamic workloads across the network. This switch also provides a rich Layer 2 and Layer 3 feature set that is ideal for many of today’s data centers, and offers industry-leading external bandwidth by being the first integrated switch to support 40 GbE external ports.
The EN4093R flexible port mapping allows you to buy only the ports that you need, when you need them, to lower acquisition and operational costs. The base switch configuration includes 24x 10 GbE port licenses that can be assigned to internal connections and 10 GbE or even 40 GbE (by using four 10 GbE licenses per 40 GbE port) external ports. You then have the flexibility of turning on more 10 GbE internal connections and more 10 GbE or 40 GbE external ports when you need them by using Lenovo Features on Demand licensing capabilities that provide “pay as you grow” scalability without the need for more hardware.
With the majority of IT organizations implementing virtualization, there is an increased need to reduce the cost and complexity of their environments. Lenovo is helping to address these requirements by removing multiple physical I/O ports. Virtual Fabric provides a way for companies to carve up 10 GbE ports into virtual NICs (vNICs) to meet those requirements with Intel processor-based compute nodes.
To help deliver maximum performance per vNIC and provide higher availability and security with isolation between vNICs, the switch uses the capabilities of its Networking Operating System. For large-scale virtualization, the Flex System solution can support up to 48 vNICs by using a pair of CN4058S 10Gb Virtual Fabric Adapters in each compute node and four EN4093R 10Gb Scalable Switches in the chassis.
The EN4093R switch offers the benefits of next-generation vNIC - Unified Fabric Port (UFP). UFP is an advanced, cost-effective solution that provides a flexible way for clients to allocate, reallocate, and adjust bandwidth to meet their ever-changing data center requirements.
VMready software on the module simplifies configuration and improves security in virtualized environments. VMready automatically detects virtual machine movement between physical servers and instantly reconfigures each VM’s network policies across VLANs to keep the network up and running without interrupting traffic or affecting performance. VMready works with all leading VM providers, such as VMware, Citrix Xen, and Microsoft Hyper-V.
Support for Edge Virtual Bridging (EVB) that is based on the IEEE 802.1Qbg standard enables scalable, flexible management of networking configuration and policy requirements per VM and eliminates many of the networking challenges that are introduced with server virtualization.
The EN4093R 10Gb Scalable Switch simplifies deployment and growth because of its innovative scalable architecture. This architecture helps increase return on investment by reducing the qualification cycle, while providing investment protection for more I/O bandwidth requirements in the future. The extreme flexibility of the switch comes from the ability to turn on more ports as required, both down to the compute node and for upstream connections (including 40 GbE). Also, as you consider migrating to a converged LAN and SAN, the EN4093R switch supports the newest protocols, including Data Center Bridging/Converged Enhanced Ethernet (DCB/CEE) that can be used in an iSCSI, Fibre Channel over Ethernet (FCoE), or NAS converged environment.
EN4093R’s stacking capabilities simplify management for clients by stacking up to eight switches that share one IP address and one management interface. Support for Switch Partition (SPAR) allows clients to virtualize the switch with partitions that isolate communications for multi-tenancy environments.
With a simple configuration change to "easy connect" mode, the EN4093R switch becomes a transparent network device that is invisible to the core and eliminates network administration concerns of Spanning Tree Protocol configuration and interoperability, VLAN assignments, and avoidance of possible loops.
By emulating a host NIC to the data center core, it accelerates the provisioning of VMs by eliminating the need to configure the typical access switch parameters.
The EN4093R switch is Lenovo's first 10 GbE Flex System offering with OpenFlow. OpenFlow is the new open 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.
Switch Center application is used for advanced levels of provisioning, management, and control, which can significantly reduce deployment and day-to-day maintenance times while providing in-depth visibility into the network performance and operations of Lenovo switches. When tools, such as VMware vRealize product suite, vCenter Server (formerly VMware Virtual Center) or vSphere are used, Switch Center provides more integration for better optimization.
The Lenovo Networking Content Pack for VMware vRealize Log Insight enables administrators to use VMware vRealize Log Insight with their Lenovo Networking deployments. This applies to VMware administrators, system administrators, and network administrators. This capability delivers automated log management that helps to provide operational efficiency in dynamic, hybrid cloud environments.The Lenovo Networking Content Pack for VMware vRealize Log Insight is custom-designed by Lenovo Networking to provide information that is specific to Lenovo Networking switches and switch configurations. When used with Log Insight, the Lenovo Networking Content Pack provides monitoring and analyses of syslogs that are issued by Lenovo Networking switches and switch configurations.
