4.10.3 I/O module naming scheme

The I/O module naming scheme follows a logical structure, similar to that of the I/O adapters.

Figure 4-41 shows the I/O module naming scheme. As time progresses this scheme might be

expanded to support future technology.

4.10.4 IBM Flex System Fabric EN4093 10 Gb Scalable Switch

The IBM Flex System Fabric EN4093 10 Gb Scalable Switch is a 10 Gb 64-port upgradeable

midrange to high-end switch module. It offers Layer 2/3 switching designed to install within the

I/O module bays of the Enterprise Chassis. The switch contains the following ports:

򐂰 Up to 42 internal 10 Gb ports

򐂰 Up to 14 external 10 Gb uplink ports (enhanced small form-factor pluggable (SFP+)

connectors)

򐂰 Up to 2 external 40 Gb uplink ports (quad small form-factor pluggable (QSFP+)

connectors)

The switch is considered suited for clients with these needs:

򐂰 Building a 10 Gb infrastructure

򐂰 Implementing a virtualized environment

򐂰 Requiring investment protection for 40 Gb uplinks

򐂰 Want to reduce total cost of ownership (TCO) and improve performance, while maintaining

high levels of availability and security

򐂰 Want to avoid oversubscription (traffic from multiple internal ports that attempt to pass

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

As listed in Table 4-11, the switch is initially licensed with fourteen 10 Gb internal ports

enabled and ten 10 Gb external uplink ports enabled. Further ports can be enabled, including

the two 40 Gb external uplink ports with the Upgrade 1 and Upgrade 2 license options.

Upgrade 1 must be applied before Upgrade 2 can be applied.

Table 4-11 lists the available parts and upgrades.
