Flex System Fabric CN4093 10Gb Converged Scalable

Switch

Product Guide (withdrawn product)

The Flex System® Fabric CN4093 10Gb Converged Scalable Switch provides unmatched scalability, port

flexibility, performance, convergence, and network virtualization, while also delivering innovations to help

address a number of networking concerns today and providing capabilities that will help you prepare for the

future. The switch offers full Layer 2/3 switching as well as FCoE Full Fabric and Fibre Channel NPV Gateway

operations to deliver a truly converged integrated solution, and it is designed to install within the I/O module

bays of the Flex System Enterprise Chassis. The switch can help clients migrate to a 10 GbE or 40 GbE

converged Ethernet infrastructure and offers virtualization features like Virtual Fabric and VMready®.

Did you know?

The CN4093 offers up to 12 external Omni Ports, which provide extreme flexibility with the choice of SFP+

based 10 Gb Ethernet connectivity or 4/8 Gb Fibre Channel connectivity, depending on the SFP+ module

used.

The base switch configuration comes standard with 22x 10 GbE port licenses that can be assigned to internal

connections or external SFP+, Omni 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+ or Omni port for one internal 10 GbE port (or vice versa). You then have the flexibility of turning on more

ports when you need them using Lenovo Features on Demand upgrade licensing capabilities that provide “pay

as you grow” scalability without the need to buy additional hardware.

Part number information The CN4093 switch is initially licensed for 22x 10 GbE ports. Further ports can be enabled with Upgrade 1 and Upgrade 2 license options. Upgrade 1 and Upgrade 2 can be applied on the switch independently from each other or in combination for full feature capability. Table 1 shows the part numbers for ordering the switches and the upgrades. Table 1.
PAGE 3
Flexible port mapping: With Networking OS version 7.8 or later clients have more flexibility in assigning ports that they have licensed on the CN4093 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 10 GbE ports and Omni Ports, or trading off four 10 GbE ports for the use of an external 40 GbE port.

For 40 GbE to 40 GbE connectivity, clients can use the affordable QSFP+ to QSFP+ DAC cables for distances up to 7 meters. For distances up to 100 m, the 40GBASE-SR4/iSR4 QSFP+ transceivers can be used with OM3 multimode fiber or up to 150 m when using OM4 multimode fiber. For distances up to 300 m, the 40GBASE-eSR4 QSFP+ transceiver can be used with OM3 multimode fiber or up to 400 m when using OM4 multimode fiber.

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 CN4093 is the embedded 10 GbE switch for a Flex System chassis to support sub-microsecond latency and up to 1.28 Tbps, while also delivering full line rate performance on Ethernet ports, making it ideal for managing dynamic workloads across the network.

CN4093 hybrid stacking capabilities simplify management for clients by stacking up to eight switches (two CN4093 and from two to six EN4093/EN4093R 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.

The switches are installed in I/O module bays in the rear of the Flex System chassis, as shown in Figure 2. Switches are normally installed in pairs because ports on the I/O adapter cards installed in the compute nodes are routed to two I/O bays for redundancy and performance. Figure 2. Location of the I/O bays in the Flex System chassis The CN4093 switch can be installed in bays 1, 2, 3, and 4 of the Flex System chassis.

The CN4093 Virtual Fabric vNIC solution is based on the Flex System Enterprise Chassis with a 10 Gb Converged Enhanced Ethernet (CEE) infrastructure and 10 Gb Virtual Fabric Adapters (VFAs) installed in each compute node. In Virtual Fabric mode, the CN4093 10 Gb switch is vNIC-aware, that is, the configuration of vNICs is done on a switch, then it propagates vNIC parameters to VFA using the DataCenter Bridging eXchange (DCBX) protocol.
