26 IBM Flex System V7000 Storage Node Introduction and Implementation Guide
Each Omni Port is capable of running in 10 Gb Ethernet or 4/8 Gb FC mode with
auto-negotiation capability.
Support for Converged Enhanced Ethernet (CEE) and Fibre Channel over Ethernet
(FCoE) over all Ethernet ports including Omni Ports (in Ethernet mode).
Support for the Full Fabric FCF (Fibre Channel Forwarder) and NPV gateway.
Support for full fabric FC services including Name Server, hardware-based Zoning.
Support for IBM vNIC (virtual network interface card) Virtual Fabric Adapter with Single
Root I/O Virtualization (SR-IOV) capability.
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 the following features:
14 internal 10 Gb Ethernet/FCoE ports
2 external 1 Gb/10 Gb 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 can easily and cost-effectively
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 provided through the following connections:
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
1.5.2 IBM Flex System Fabric EN4093 and EN4093R 10 Gb Scalable Switch
The IBM Flex System Fabric EN4093 and EN4093R 10 Gb Scalable Switches are 10 Gb
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 the
following features:
Up to 42 internal 10 Gb ports
Up to 14 external 10 Gb uplink ports (SFP+ connectors)
Up to 2 external 40 Gb uplink ports (QSFP+ connectors)
The switch is considered particularly suited for these needs:
Building a 10 Gb infrastructure
Implementing a virtualized environment
Investment protection for 40 Gb uplinks
TCO reduction, improving 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 and performance impact)
