Introduction

The Lenovo ThinkSystem NE2552E Flex Switch is an embedded switch module for Flex System that is designed for the data center to provide 10 Gb/25 Gb/50 Gb Ethernet server connectivity with 40 Gb/50 Gb/100 Gb Ethernet upstream links. It is an enterprise class Layer 2 and Layer 3 full featured switch that delivers line-rate, high-bandwidth switching, filtering, and traffic queuing without delaying data. Large data center-grade buffers help keep traffic moving, while the numerous high-availability software features help provide high availability for business sensitive traffic.

The NE2552E Flex Switch has 28 internal ports that can be configured as 28x 10 GbE ports, 28x 25 GbE ports, 14x 50 GbE ports, or certain combinations of 10 GbE, 25 GbE, and 50 GbE ports.

For external network connectivity, the NE2552E Flex Switch offers 8x SFP28/SFP+ ports that support 10 GbE SFP+ and 25 GbE SFP28 optical transceivers, active optical cables (AOCs), and direct attach copper (DAC) cables. The switch also offers 4x QSFP28 ports that support 100 GbE QSFP28 or 40 GbE QSFP+ optical transceivers, active optical cables (AOCs), and direct attach copper (DAC) cables. The QSFP28 ports can also be split out into two 50 GbE or four 25 GbE (for 100 GbE QSFP28), or four 10 GbE (for 40 GbE QSFP+) connections by using breakout cables.

The NE2552E Flex Switch is ideal for hyperconverged and cloud solutions, as well as latency-sensitive applications, such as high-performance computing clusters and financial applications.

Did you know?

The NE2552E Flex Switch runs Enterprise Networking Operating System (ENOS), which is a data center-class NOS progressively developed over the past decade to deliver highly reliable, high-performance Ethernet and converged switching and interoperability with existing network infrastructures. ENOS has a feature-rich design with virtualization, high availability, and enterprise class Layer 2 and Layer 3 functionality.

The NE2552E is cloud-ready with support for 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 customer networking requirements.

With support for Converged Enhanced Ethernet (CEE), the NE2552E can be used as an FCoE transit device and is ideal for network-attached storage (NAS) and iSCSI environments.

Key features

The ThinkSystem NE2552E Flex Switch is considered particularly suited for the following environments:

  • Mixed 10 GbE, 25 GbE, and 50 GbE embedded server connectivity with 40 GbE, 50 GbE, or 100 GbE upstream aggregation
  • Cloud and virtualization solutions with integration into Lenovo and third-party IT and cloud infrastructure management tools
  • Embedded network connectivity with support for converged SAN and LAN via NAS, iSCSI, or FCoE
    • Reduced I/O cost (CAPEX) with fewer adapters, cables, and transceivers to purchase
    • Reduced complexity (OPEX) with fewer components to manage and lower energy cost
  • Web-scale and hyperconverged solutions
  • Applications demanding better performance and lower latency

The NE2552E Flex Switch offers the following key features and benefits:

  • High performance

    The 10 Gb/25 Gb/50 Gb Ethernet NE2552E Flex Switch with 40 Gb/50 Gb/100 Gb Ethernet uplinks provides a combination of low latency, non-blocking line-rate switching, and ease of management.

  • Lower power and better cooling

    The embedded design of the NE2552E Flex Switch helps reduce data center air conditioning costs and power consumption.

  • Layer 3 functionality

    The NE2552E Flex Switch includes Layer 3 functionality, which provides security and performance benefits, as inter-VLAN traffic stays within the switch. This switch also provides the full range of Layer 3 protocols from static routes for technologies, such as Open Shortest Path First (OSPF) and Border Gateway Protocol (BGP) for enterprise customers.

  • Converged fabric

    The NE2552E Flex Switch supports Converged Enhanced Ethernet (CEE) which helps enable customers to combine storage, messaging traffic, VoIP, video, and other data on a common data center lossless Ethernet infrastructure. As a result, customers can deploy a single server interface for multiple data types, which can simplify the deployment and management of server network connectivity while maintaining the high availability and robustness that is required for storage transactions.

  • Fault tolerance

    The NE2552E Flex Switch learns alternate routes automatically and performs faster convergence if there is a link or switch failure.

  • Seamless interoperability

    The NE2552E Flex Switch performs seamlessly with other vendors' upstream switches.

  • Virtualization

    The NE2552E Flex Switch can help customers address I/O requirements for multiple NICs while reducing cost and complexity. By using Unified Fabric Port, customers can partition a physical NIC into multiple virtual ports (2 - 8 vPorts) and create a virtual pipe between the adapter and the switch for improved performance, availability, and security.

    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 NE2552E Flex Switch becomes a transparent network device that is invisible to the core and eliminates network administration concerns of Spanning Tree Protocol configuration and interoperability and VLAN assignments and avoids any 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.

  • Advanced network management

    The NE2552E Flex Switch integrates with Lenovo XClarity (planned for 3Q 2018) for centralized data center management. Integration with third-party automation, deployment, and monitoring tools, such as VMware vRealize Orchestrator and Log Insight, Ansible DevOps tools, and OpenStack cloud, provides rapid resource provisioning and simplified configuration management across the network.

      • Two-tier vLAGs with VRRP enables active/active VRRP to reduce routing latency
    • Switch partitioning (SPAR):
      • SPAR forms separate virtual switching contexts by segmenting the data plane of the module. Data plane traffic is not shared between SPARs on the same switch.
      • SPAR operates as a Layer 2 broadcast network. Hosts on the same VLAN that are attached to a SPAR can communicate with each other and with the upstream switch. Hosts on the same VLAN but attached to different SPARs communicate through the upstream switch.
      • SPAR is implemented as a dedicated VLAN with a set of internal compute node ports and a single external port or link aggregation (LAG). Multiple external ports or LAGs are not allowed in SPAR. A port can be a member of only one SPAR.
      • SPAR operates in one of the following modes:
        • Pass-through Domain (or VLAN-agnostic) mode

          In VLAN-agnostic mode (default configuration), the NE2552E transparently forwards VLAN tagged frames without filtering on the customer VLAN tag. This mode provides an end host view to the upstream network. When FCoE is used, the switch can be connected to the FCoE transit switch or FCoE gateway (FC Forwarder [FCF]) device.

        • Local Domain (or VLAN-aware) mode

          In VLAN-aware mode (optional configuration), the NE2552E provides more security for multi-tenant environments by extending client VLAN traffic isolation to the switch module and its external ports. VLAN-based access control lists (ACLs) can be configured on the NE2552E. When FCoE is used, the switch operates as an FCoE transit switch and it should be connected to the FCF device.

  • Converged Enhanced Ethernet:
    • Priority-Based Flow Control (PFC) (IEEE 802.1Qbb) extends 802.3x standard flow control to allow the switch to pause traffic that is based on the 802.1p priority value in each packet’s VLAN tag.
    • Enhanced Transmission Selection (ETS) (IEEE 802.1Qaz) provides a method for allocating link bandwidth that is based on the 802.1p priority value in each packet’s VLAN tag.
    • Data Center Bridging Capability Exchange Protocol (DCBX) (IEEE 802.1AB) allows neighboring network devices to exchange information about their capabilities.

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

The NE2552E switches can be installed in bays 1, 2, 3, and 4 of the Enterprise chassis. A supported 10 GbE, 25 GbE, or 50 GbE adapter must be installed in the corresponding slot of the compute node. Each adapter can use one (10/25 GbE) or two (50 GbE) lanes to connect to the respective I/O module bay.

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 Fabric Connector, and the adapter is not required. However, the Fabric Connector can be replaced with the adapter when needed. In such a case, the integrated NIC is disabled.

Internal ports on the NE2552E switch are combined into seven 4-port groups:

  • INTA1, INTB1, INTA2, INTB2
  • INTA3, INTB3, INTA4, INTB4
  • INTA5, INTB5, INTA6, INTB6
  • INTA7, INTB7, INTA8, INTB8
  • INTA9, INTB9, INTA10, INTB10
  • INTA11, INTB11, INTA12, INTB12
  • INTA13, INTB13, INTA14, INTB14

All internal ports in the same 4-port group operate at the same speed (10 Gbps, 25 Gbps, or 50 Gbps [2x 25 Gbps]). For 50 Gbps internal connections, two 25 Gbps ports (INTAx and INTBx) are combined into a single 50 Gbps (2x 25 Gbps) port (INTAx).

Note: The switch can operate in any combination of up to three of five different port speeds supported (10 Gbps, 25 Gbps, 40 Gbps, 50 Gbps, and 100 Gbps) across all ports on the switch; a combination of four or five different port speeds is not supported.

The following figure shows internal port mappings and speeds for various 4-port group configurations.
