Introduction

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.

  • Cloud ready, VM-aware networking

    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.

  • Simplified network infrastructure

    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 a converged iSCSI, Fibre Channel over Ethernet (FCoE), or NAS 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.

  • Transparent networking capability

    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.

  • SDN ready, OpenFlow enabled

    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.

  • Advanced network management

    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.

The part number for the switch includes the following items:

  • One Lenovo Flex System Fabric EN4093R 10Gb Scalable Switch
  • Documentation package

Note: QSFP+ and SFP/SFP+ transceivers and DAC cables are not included and should be ordered together with the switch (see Transceivers and cables for details).

The switch does not include a serial management cable; the optional Flex System Management Serial Access Cable (part number 90Y9338) is supported and includes two cables: a mini-USB-to-RJ-45 serial cable and a mini-USB-to-DB9 serial cable. These cables can be used to connect to the switch locally for configuration tasks and firmware updates.

The part numbers for the upgrades (part numbers 49Y4798 and 88Y6037) include the following items:

  • Features on Demand Activation Flyer
  • Upgrade authorization letter

The base switch and upgrades feature the following default configurations:

  • Part number 00FM514 is for the base physical device and includes 14 internal 10 GbE ports enabled (one to each compute node) and 10 external 10 GbE ports enabled.
  • Part number 49Y4798 (Upgrade 1) can be applied on the base switch when you use 4-port adapters that are installed in each compute node. This upgrade enables 14 more internal ports, for a total of 28 ports. The upgrade also enables two 40 GbE external ports. This upgrade requires the base switch.
  • Part number 88Y6037 (Upgrade 2) can be applied on top of the Upgrade 1 when you need more external bandwidth on the switch or if you need more internal bandwidth to the compute nodes with the 6-port capable adapters. The upgrade enables the remaining four external 10 GbE external ports and 14 internal 10 GbE ports for a total of 42 internal ports (three to each compute node).

With flexible port mapping, customers have more flexibility in assigning ports that they licensed on the EN4093R, which can help eliminate or postpone the need to purchase upgrades. Although the base model and upgrades still activate specific ports, flexible port mapping provides clients with the capability of reassigning ports as needed by moving internal and external 10 GbE ports, or trading off four 10 GbE ports for the use of an external 40 GbE port. This feature is valuable when you consider the flexibility with the base license and with Upgrade 1.

Note: Flexible port mapping is supported in Stacking mode with Networking OS version 8.3 or later.

With flexible port mapping, clients have the following licenses for a specific number of ports:

  • Part number 00FM514 is for the base switch and it provides 24x 10 GbE port licenses that can enable any combination of internal and external 10 GbE ports and external 40 GbE ports (with the use of four 10 GbE port licenses per one 40 GbE port).
  • Part number 49Y4798 (Upgrade 1) upgrades the base switch by activating 14 internal 10 GbE ports and two external 40 GbE ports, which is equivalent to adding 22 10 GbE port licenses for a total of 46x 10 GbE port licenses. Any combination of internal and external 10 GbE ports and external 40 GbE ports (with the use of four 10 GbE port licenses per one 40 GbE port) can be enabled with this upgrade. This upgrade requires the base switch.
  • Part number 88Y6037 (Upgrade 2) requires the base switch and that Upgrade 1 is activated. Upgrade 2 activates all of the ports on the EN4093R, which is 42 internal 10 GbE ports, 14 external SFP+ ports, and 2 external QSFP+ ports.

Note: When Upgrade 1 and Upgrade 2 are activated, flexible port mapping is no longer used because all the ports on the EN4093R are enabled.

The supported port combinations on the switch and required upgrades are listed in the following tables.

Transceivers and cables

With the flexibility of the EN4093R switch, customers can use the following connectivity technologies:

  • For 1 GbE links, customers can use RJ-45 SFP transceivers with UTP cables up to 100 meters. Customers that need longer distances can use a 1000BASE-SX transceiver, which can drive distances up to 220 meters with 62.5 µ multi-mode fiber (OM1) and up to 550 meters with 50 µ multi-mode fiber (OM2), or the 1000BASE-LX transceivers that support distances up to 10 kilometers with single-mode fiber (1310 nm).
  • For 10 GbE links (on external SFP+ ports), customers can use SFP+ direct-attached copper (DAC) cables for in-rack cabling for distances up to 7 meters or SFP+ active optical cables (AOCs) for distances up to 20 meters. These cables have SFP+ connectors on each end, and they do not need separate transceivers. For distances up to 30 meters, the 10GBASE-T SFP+ transceiver can be used with Category 6a or 7 RJ-45 UTP cables. For longer distances, the 10GBASE-SR transceiver supports distances up to 300 meters over OM3 multimode fiber or up to 400 meters over OM4 multimode fiber. The 10GBASE-LR transceivers can support distances up to 10 kilometers on single mode fiber.

    To increase the number of available 10 GbE ports, customers can split out four 10 GbE ports for each 40 GbE port by using QSFP+ DAC or active optical breakout cables for distances up to 5 meters. For distances up to 100 meters, the 40GBASE-iSR4 QSFP+ transceivers can be used with OM3 optical MPO-to-LC breakout cables or up to 150 meters with OM4 optical MPO-to-LC breakout cables. For longer distances, the 40GBASE-eSR4 transceivers can be used with OM3 optical MPO-to-LC breakout cables for distances up to 300 meters or OM4 optical MPO-to-LC breakout cables for distances up to 400 meters.

  • For 40 GbE to 40 GbE connectivity, customers can use the affordable QSFP+ to QSFP+ DAC cables for distances up to 7 meters or QSFP+ to QSFP+ active optical cables for distances up to 20 meters.

    With multimode fiber LC cables, customers can use the 40GBASE QSFP+ bi-directional transceivers for distances up to 100 meters with OM3 MMF LC cables or up to 150 meters with OM4 MMF LC cables.

    With multimode fiber MPO cables, customers can use the 40GBASE-SR4/iSR4 QSFP+ transceivers for distances up to 100 meters with OM3 MMF MPO cables or up to 150 meters with OM4 MMF MPO cables. For distances up to 300 meters, the 40GBASE-eSR4 QSFP+ transceiver can be used with OM3 MMF MPO cables or up to 400 meters with OM4 MMF MPO cables.

    For distances up to 10 kilometers, the 40GBASE-LR4 QSFP+ transceiver can be used with single mode fiber LC cables.

The supported transceivers and cables are listed in the following table.

Chassis and adapters

The switches are installed in I/O module bays in the rear of the Flex System Chassis, as shown in the following figure. Switches are normally installed in pairs because ports on the I/O adapters that are installed in the compute nodes are routed to two I/O bays for redundancy and performance. 

Location of the switch bays in the Flex System Enterprise Chassis
Figure 3. Location of the I/O bays in the Flex System Enterprise Chassis

The 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.
