IBM Flex System V7000 Storage Node Introduction and Implementation Guide

The 10 Gb Ethernet switch supports single compute node port capability (14 ports). Dual 
compute node port capability (28 ports) and triple compute node port capability (42 ports) are 
available with optional licenses.

The base model of this scalable switch provides:

��

14 internal 10 Gb Ethernet/FCoE ports 

��

2 external 1Gb/10Gb Ethernet/FCoE ports

��

6 external flexible ports, usable for either 10 Gb Ethernet/FCoE or 4/8 Gb Fibre Channel. 

With the optional licensing for pay-as-you-grow scalability, you easily and cost-effectively can 
enable additional internal 10 Gb Ethernet/FCoE ports, external 10 Gb/40 Gb Ethernet/FCoE 
ports and external flexible ports, usable for either 10 Gb Ethernet/FCoE or 4/8 Gb Fibre 
Channel.

For switch management access can be via:

– A SSHv2/Telnet connection to the embedded command-line interface (CLI)
– A terminal emulation program connection to the serial port interface
– A Web browser-based interface (https/http) connection to the switch

The IBM Flex System Fabric EN4093 and EN4093R 10Gb Scalable Switches are 10Gb 
64-port upgradable midrange to high-end switch module, offering Layer 2/3 switching 
designed to install within the I/O module bays of the Enterprise Chassis. The switch has:

��

Up to 42 internal 10Gb ports

��

Up to 14 external 10Gb uplink ports (SFP+ connectors)

��

Up to 2 external 40Gb uplink ports (QSFP+ connectors)

The switch is considered particularly suited for:

– Building a 10Gb infrastructure
– Implementing a virtualized environment
– Investment protection for 40Gb uplinks
– TCO reduction, improve performance, while maintaining high levels of availability and 

security

– Oversubscription avoidance (Traffic from multiple internal ports attempting to pass 

through a lower quantity of external ports, leading to congestion & performance impact)

The rear of the switch has 14 SPF+ module ports and 2QSFP+ module ports. The QSFP+ 
ports can be used to provide either two 40Gb uplinks or eight 10Gb ports, using one of the 
supported QSFP+ to 4x 10Gb SFP+ cables. This cable splits a single 40Gb QSPFP port into 
4 SFP+ 10Gb ports. 

For management of the switch there is a mini USB port and also an Ethernet management 
port provided.

IBM Flex System Fabric EN4093R : IBM Flex System Fabric 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 multitenancy 
environments.
