Such consolidation simplifies the data center infrastructure and helps reduce the number of discrete devices, management consoles, and management systems while leveraging the 1 Gb Ethernet infrastructure. In addition, the next-generation switch module hardware supports IPv6 Layer 3 frame forwarding protocols. This Scalable Switch delivers cost savings with flexible port mapping and Features on Demand upgrades, efficient traffic management, increased external bandwidth, and strong Ethernet switching price/performance.

Did you know?

The base switch configuration comes standard with 24x 1 GbE port licenses that can be assigned to internal or external 1 GbE connections or even external SFP+ ports with flexible port mapping. For example, this feature allows you to trade off one external 1 GbE RJ-45 port for one internal 1 GbE port (or vice versa) or trade off ten 1 GbE ports for one 10 GbE port. You then have the flexibility of turning on more ports when you need them using IBM Features on Demand upgrade licensing capabilities that provide “pay as you grow” scalability without the need to buy additional hardware.

Delivering advanced virtualization awareness and cloud readiness helps simplify management and automates VM mobility by making the network VM aware with IBM VMready® which works with all the major hypervisors.

The part number for the switch, 49Y4294, includes the following items:
  • One IBM Flex System EN2092 1Gb Ethernet Scalable Switch
  • Important Notices Flyer
  • Warranty Flyer
  • Documentation CD-ROM

The switch does not include a serial management cable. However, the optional IBM Flex System Management Serial Access Cable, 90Y9338, is supported and contains two cables, a mini-USB-to-RJ45 serial cable and a mini-USB-to-DB9 serial cable, either of which can be used to connect to the switch locally for configuration tasks and firmware updates.

The part numbers for the upgrades, 90Y3562 and 49Y4298, include the following items:
  • Feature on Demand Activation Flyer
  • Upgrade activation key

The base switch and upgrades are as follows:
  • 49Y4294 is the part number for the base switch, and it comes with 14 internal 1 GbE ports enabled, one to each compute node and ten external 1 GbE ports enabled. All external 1 GbE ports have RJ-45 connectors.
  • 90Y3562 (Upgrade 1) can be applied on the base switch to take full advantage of four-port adapter cards installed in each compute node. This upgrade enables 14 additional internal ports, for a total of 28 ports (two ports to each node). The upgrade also enables 10 additional external 1 GbE ports for a total of twenty 1 GbE external RJ-45 ports. This upgrade requires the base switch.
  • 49Y4298 (10Gb Uplinks) can be applied on the base switch when you need more external bandwidth. The upgrade enables four external 10 GbE ports with SFP+ connectors (SFP+ transceivers or DAC cables are not included). This upgrade requires the base switch.
  • Both 90Y3562 (Upgrade 1) and 49Y4298 (10Gb Uplinks) can be applied on the switch at the same time to allow you to use 28 internal 10 GbE ports leveraging all four ports on an four-port expansion card, and to utilize all external ports on the switch.

Flexible port mapping: With IBM Networking OS version 7.8 or later clients have more flexibility in assigning ports that they have licensed on the EN2092 which can help eliminate or postpone the need to purchase upgrades. While 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 1 GbE ports or trading off ten 1 GbE ports for the use of an external 10 GbE port (or vice versa). This is very valuable when you consider the flexibility with the base license and with 10Gb Uplinks upgrade.

With flexible port mapping, clients have licenses for a specific number of ports:
  • 49Y4294 is the part number for the base switch, and it provides 24x 1 GbE port licenses that can enable any combination of internal and external 1 GbE ports and external 10 GbE ports (with the use of ten 1 GbE port licenses per one 10 GbE port).
  • 90Y3562 (Upgrade 1) upgrades the base switch by activation of 14 internal 1 GbE ports and ten external 1 GbE ports which is equivalent to adding 24 more 1 GbE port licenses for a total of 48x 1 GbE port licenses. Any combination of internal and external 1 GbE ports and external 10 GbE ports (with the use of ten 1 GbE port licenses per one 10 GbE port) can be enabled with this upgrade. This upgrade requires the base switch.
  • 49Y4298 (10Gb Uplinks) upgrades the base switch by activation of four external 10 GbE ports for a total of 24x 1 GbE ports and 4x 10 GbE ports. With the use of one external 10 GbE port license for ten 1 GbE ports, any combination of internal and external 1 GbE ports and external 10 GbE ports can be enabled with this upgrade. This upgrade requires the base switch.
  • Both 90Y3562 (Upgrade 1) and 49Y4298 (10Gb Uplinks) simply activate all the ports on the EN2092 which is 28 internal 1 GbE ports, 20 external 1 GbE ports, and four external 10 GbE SFP+ ports.

Note: When both Upgrade 1 and 10Gb Uplinks are activated, flexible port mapping is no longer used because all the ports on the EN2092 are enabled.

With the flexibility of the IBM switch, clients can take advantage of the technologies that they require for multiple environments:
  • For 1 GbE links, you can use RJ-45 UTP cables up to 100 m. Clients that need longer distances can leverage the SFP/SFP+ external ports using a 1000BASE-SX transceiver which can drive distances up to 220 meters using 62.5 µ multi-mode fiber and up to 550 meters with 50 µ multi-mode fiber or the 1000BASE-LX transceivers that support distances up to 10 kilometers using single-mode fiber (1310 nm).
  • For 10 GbE (supported on external SFP+ ports), you can use direct-attached copper (DAC) SFP+ cables for in-rack cabling and distances up to 7 m. These DAC cables have SFP+ connectors on each end, and they do not need separate transceivers. For longer distances the 10GBASE-SR transceiver can support distances up to 300 meters over OM3 multimode fiber or up to 400 meters over OM4 multimode fiber with LC connectors. The 10GBASE-LR transceivers can support distances up to 10 kilometers on single mode fiber with LC connectors.

Benefits

The IBM Flex System EN2092 1Gb Scalable Switch is considered particularly suited for these clients:

  • Clients who want to leverage GbE in their infrastructure
  • Clients who are implementing a virtualized environment and require multiple GbE ports
  • Clients who require investment protection for 10 Gb external ports
  • Clients who want to reduce TCO and improve performance while maintaining high levels of availability and security
  • Clients who want to avoid or minimize oversubscription, which can result in congestion and loss of performance
  • Clients who want to implement a converged infrastructure with NAS or iSCSI

The switch offers the following key benefits:
  • Increases network performance

    With the growth of virtualization and the evolution of cloud, many of today’s applications require low latency and high-bandwidth performance. The EN2092 delivers non-blocking architecture with 176 Gbps throughput and full line rate performance, making it ideal for managing dynamic workloads across the network. In addition, the switch provides a rich Layer 2 and Layer 3 feature set that is ideal for many of today’s data centers, plus it offers a combined external bandwidth of 60 Gb.

  • Pay as you grow investment protection and lower total cost of ownership

    The EN2092's flexible port mapping allows you to reallocate ports as you need which helps reduce acquisition and operational costs. The base switch configuration includes 24x 1 GbE port licenses that can be assigned to internal 1 GbE connections and 1 GbE or even 10 GbE (by using ten 1 GbE licenses per one 10 GbE port) external ports. You then have the flexibility of turning on more 1 GbE connections to the compute node and more 1 GbE or 10 GbE external ports when you need them using IBM Features on Demand licensing capabilities that provide “pay as you grow” scalability without the need to buy additional hardware.

  • Cloud ready

    Delivering advanced virtualization awareness helps simplify management and automates VM mobility by making the network VM aware with IBM VMready® which works with all the major hypervisors. For companies using VMware or Linux KVM, IBM System Networking’s SDN VE offerings (sold separately) enable network administrators to simplify management by having a consistent virtual and physical networking environment. Network policies migrate automatically along with virtual machines (VMs) to ensure that security, performance, and access remain intact as VMs move from compute node to compute node.

    Support for Switch Partition (SPAR) allows clients to virtualize the switch with partitions that isolate communications for multi-tenancy environments.

  • Simplifies network infrastructure

    The EN2092 1Gb Scalable Switch simplifies deployment and growth by using its innovative scalable architecture. This architecture helps increase return on investment by reducing the qualification cycle, while providing investment protection for additional I/O bandwidth requirements in the future. The extreme flexibility of the switch comes from the ability to turn on additional ports as required, both down to the compute node and for upstream connections (including 10 GbE). Also, as you consider migrating to a converged LAN and SAN, the EN2092 switch can be leveraged in either an iSCSI or NAS converged environment.

  • Simplified management

    A key challenge is the management of a discrete network environment. The EN2092 1Gb Scalable Switch supports a command-line interface (CLI) for integration into existing scripting and automation. Network management can be simplified by using port profiles, topology views, and virtualization management.

    For more advanced levels of management and control, IBM offers IBM System Networking Switch Center (SNSC), which can significantly reduce deployment and day-to-day maintenance times, while providing in-depth visibility into the network performance and operations of IBM switches. Plus, when leveraging tools like VMware vCenter Server or vSphere, SNSC provides additional integration for better optimization.

Supported chassis and adapter cards

The switches are installed in switch bays in the rear of the IBM Flex System Enterprise Chassis, as shown in the following figure. Switches are normally installed in pairs because I/O adapter cards installed in the compute nodes route to two switch bays for redundancy and performance.

Location of the switch bays in the Enterprise Chassis
Figure 2. Location of the switch bays in the IBM Flex System Enterprise Chassis

The midplane connections between the adapters installed in the compute nodes to the switch bays in the chassis are shown diagrammatically in the following figure. The figure shows both half-wide compute nodes, such as the x240 with two adapters, and full-wide compute nodes, such as the p460 with four adapters.

Logical layout of the interconnects between I/O adapters and I/O modules
Figure 3. Logical layout of the interconnects between I/O adapters and I/O modules

The IBM Flex System EN2092 Scalable Switch can be installed in bays 1, 2, 3, and 4 of the Enterprise chassis. A supported adapter card must be installed in a corresponding slot of the compute node (slot A1 when switches are installed in bays 1 and 2 or slot A2 when switches are in bays 3 and 4).

Prior to Networking OS 7.8, with four-port adapters, an optional Upgrade 1 (90Y3562) was required for the switch to allow communications on all four ports. With IBM Networking OS 7.8 or later, there is no need to buy additional switch upgrades for 4-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 used; clients have the choice of purchasing Upgrade 1 or 10Gb Uplinks upgrade for additional ports.

In compute nodes that have an integrated dual-port 10 GbE network interface controller (NIC), NIC's ports are routed to bays 1 and 2 with a specialized periscope connector, and the adapter card in slot A1 is not required. However, when needed, the periscope connector can be replaced with the adapter card. In such a case integrated NIC will be disabled.

Note: 10 GbE LOM and adapters supported by the EN4092 operate at 1 GbE speeds.

The following table shows the connections between adapters installed in the compute nodes to the switch bays in the chassis.

Typical configurations

Prior to IBM Networking OS 7.8, compute nodes with 4-port network adapters required Upgrade 1 for the EN2092 to enable connectivity on all four adapter ports despite of number of compute nodes and external connections used. With the introduction of flexible port mapping in IBM Networking OS 7.8, if the Flex System chassis is not fully populated with the compute nodes that have four network ports, there might be no need to buy Upgrade 1.

Consider the following scenario. You are planning to install ten x240 compute nodes with EN2024 adapters or ten high-density x222 compute nodes that will be connected to two EN2092 switches installed in I/O bays 1 and 2. You are also planning to use four external 1 GbE ports on each EN2092 for the connectivity to the upstream network. In this scenario, the total number of 1 GbE ports needed per one EN2092 is 24. The base switch supplies required 24 port licenses; therefore, the solution can be implemented without the need to buy Upgrade 1.
