Ibm Flex System En4091 10 Gb Ethernet Pass-Thru; Ibm Flex System En2092 1 Gb Ethernet Scalable Switch - IBM V7000 Introduction And Implementation Manual

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

1.5.3 IBM Flex System EN4091 10 Gb Ethernet Pass-thru

The EN4091 10Gb Ethernet Pass-thru module offers a 1 for 1 connection between a single
node bay and an I/O module uplink. It has no management interface and can support both
1 Gb and 10 Gb dual-port adapters installed in the compute nodes. If quad-port adapters are
installed in the compute nodes, only the first two ports will have access to the pass-thru
module's ports.
The necessary 1 GbE or 10 GbE module (SFP, SFP+ or DAC) must also be installed in the
external ports of the pass-thru, to support the speed wanted (1 Gb or 10 Gb) and medium
(fiber optic or copper) for adapter ports on the compute nodes.
Four-port adapters: The EN4091 10 Gb Ethernet Pass-thru has only 14 internal ports. As a
result, only two ports on each compute node are enabled, one for each of two pass-thru
modules installed in the chassis. If four-port adapters are installed in the compute nodes,
ports 3 and 4 on those adapters are not enabled.

Flex System EN4091 10Gb Ethernet Pass-thru Module, TIPS0865.

1.5.4 IBM Flex System EN2092 1 Gb Ethernet Scalable Switch

The EN2092 1 Gb Ethernet Switch provides support for L2/L3 switching and routing. The
switch has:
Up to 28 internal 1 Gb ports
Up to 20 external 1 Gb ports (RJ45 connectors)
Up to 4 external 10 Gb uplink ports (SFP+ connectors)
The switch comes standard with 14 internal and 10 external Gigabit Ethernet ports enabled.
Further ports can be enabled, including the four external 10 Gb uplink ports.
