Lenovo Flex System Fabric EN4093R 10Gb Scalable
Switch
Product Guide
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 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.

Did 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.

Key features
The Flex System Fabric EN4093R 10Gb Scalable Switch is considered particularly suited for the following
customers:
Customers who want to use 10 GbE communications between compute nodes in the chassis but still
require upstream 1 GbE connections to their infrastructure.
Customers who are implementing a virtualized environment.
Customers who require investment protection for 40 GbE external ports.
Customers who want to reduce total cost of ownership (TCO) and improve performance while maintaining
high levels of availability and security.
Customers who are interested in Software Defined Networking by using the OpenFlow standard.
Customers who want to avoid or minimize oversubscription, which can result in congestion and loss of
performance.
Customers who want to implement a converged infrastructure with NAS, iSCSI or FCoE. For FCoE
implementations, the EN4093R acts as a transit switch that forwards FCoE traffic upstream to other
devices, such as the Lenovo RackSwitch™ G8264CS, Brocade VDX, or Cisco Nexus 5548/5596, where
the FC traffic is broken out.
The switches offer the following key features and benefits:
Increased performance
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.
"Pay as you grow" investment protection and lower TCO
The EN4093R flexible port mapping allows customers to buy only the ports that they need, when they 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. Customers then have the flexibility of turning on more 10 GbE
internal connections and more 10 GbE or 40 GbE external ports when needed by using Lenovo Features
on Demand licensing capabilities that provide “pay as you grow” scalability without the need for more
hardware.
Cloud ready, optimized network virtualization with virtual NICs
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.
