a. For Power Systems compute nodes: if the chassis is configured with the power management policy “AC Power
Source Redundancy with Compute Node Throttling Allowed”, some maximum chassis configurations containing
Power Systems compute nodes with large populations of 32GB DIMMs may result in the chassis having insufficient
power to power on all 14 compute nodes bays. In such circumstances, only 13 of the 14 bays would be allowed to
be powered on.

1.4 Switch upgrades
Various IBM Flex System switches can be upgraded via software licenses to enable
additional ports or features.

Switches covered in this section:
1.4.1, “IBM Flex System Fabric CN4093 10Gb Converged Scalable Switch” on page 9
1.4.2, “IBM Flex System Fabric EN4093 & EN4093R 10Gb Scalable Switch” on page 10
1.4.3, “IBM Flex System EN2092 1Gb Ethernet Scalable Switch” on page 11
1.4.4, “IBM Flex System IB6131 InfiniBand Switch” on page 11
1.4.5, “IBM Flex System FC5022 16Gb SAN Scalable Switch” on page 12

1.4.1 IBM Flex System Fabric CN4093 10Gb Converged Scalable Switch
The CN4093 switch is initially licensed for fourteen 10 GbE internal ports, two external 10
GbE SFP+ ports, and six external Omni Ports enabled.

Further ports can be enabled, including 14 additional internal ports and two external 40 GbE
QSFP+ uplink ports with the Upgrade 1 (00D5845) and 14 additional internal ports and six
additional external Omni Ports with the Upgrade 2 (00D5847) 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 1-8 shows the part numbers for ordering the switches and the upgrades.

00D5847 A3HM / ESU2 Upgrade 2
a. The first feature code listed is for configurations ordered through System x sales channels. The second feature
code is for configurations ordered through the IBM Power Systems channel.

Each upgrade license enables additional internal ports. To take full advantage of those ports,
each compute node needs the appropriate I/O adapter installed:
The base switch requires a two-port Ethernet adapter (one port of the adapter goes to
each of two switches)
Adding Upgrade 1 or Upgrade 2 requires a four-port Ethernet adapter (two ports of the
adapter to each switch) to use all internal ports
Adding both Upgrade 1 and Upgrade 2 requires a six-port Ethernet adapter (three ports to
each switch) to use all internal ports


1.4.2 IBM Flex System Fabric EN4093 & EN4093R 10Gb Scalable Switch
The EN4093 and EN4093R are 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 four additional SFP+ 10Gb ports with
Upgrade 2 license options.

Upgrade 1 must be applied before Upgrade 2 can be applied. These are IBM Features on
Demand license upgrades.

Table 1-9 lists the available parts and upgrades.

Scalable Switch (Upgrade 2) (requires
Upgrade 1):
Adds 4x external 10 Gb uplinks
Add 14x internal 10 Gb ports

Each upgrade license enables additional internal ports. To take full advantage of those ports,
each compute node needs the appropriate I/O adapter installed:
The base switch requires a two-port Ethernet adapter (one port of the adapter goes to
each of two switches)
Upgrade 1 requires a four-port Ethernet adapter (two ports of the adapter to each switch)
to use all internal ports
Upgrade 2 requires a six-port Ethernet adapter (three ports to each switch) to use all
internal ports

Consideration: Adding Upgrade 2 enables an additional 14 internal ports. This allows a
total of 42 internal ports -- three ports connected to each of the 14 compute nodes. To take
full advantage of all 42 internal ports, a 6-port or 8-port adapter is required, such as the
CN4058 8-port 10Gb Converged Adapter.

Upgrade 2 still provides a benefit with a 4-port adapter because this upgrade enables an
extra four external 10 Gb uplinks as well.


1.4.3 IBM Flex System EN2092 1Gb Ethernet Scalable Switch
The EN2092 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 with IBM
Features on Demand license upgrades. Upgrade 1 and the 10 Gb Uplinks upgrade can be
applied in either order.

a. The first feature code listed is for configurations ordered through System x sales channels. The
second feature code is for configurations ordered through the IBM Power Systems channel.

The standard switch has 14 internal ports, and the Upgrade 1 license enables 14 additional
internal ports. To take full advantage of those ports, each compute node needs the
appropriate I/O adapter installed:
The base switch requires a two-port Ethernet adapter installed in each compute node (one
port of the adapter goes to each of two switches)
Upgrade 1 requires a four-port Ethernet adapter installed in each compute node (two ports
of the adapter to each switch)

1.4.4 IBM Flex System IB6131 InfiniBand Switch
The IBM Flex System IB6131 InfiniBand Switch is a 32 port InfiniBand switch. It has 18
FDR/QDR (56/40 Gbps) external ports and 14 FDR/QDR (56/40 Gbps) internal ports for
connections to nodes.

The x86 compute nodes support an IBM standard USB flash drive (USB Memory Key) option
preinstalled with VMware ESXi or VMware vSphere. It is fully contained on the flash drive,
without requiring any disk space.

On the x240 the USB memory keys plug into the USB ports on the optional x240 USB
Enablement Kit. On the x220 and x440, the USB memory keys plug directly into USB ports on
the system board.

Table 2-9 lists the ordering information for the VMware hypervisor options.

special air baffles that cannot be installed at the same time.

You can use the Blank USB Memory Key, 41Y8298, to use any available IBM customized
version of the VMware hypervisor. The VMware vSphere hypervisor with IBM customizations
can be downloaded from the following website:
http://ibm.com/systems/x/os/vmware/esxi

Power Systems compute nodes do not support VMware ESXi installed on a USB Memory
Key. Power Systems compute nodes support IBM PowerVM® as standard.

These servers do support virtual servers, also known as logical partitions or LPARs. The
maximum number of virtual serves is 10 times the number of cores in the compute node:
p24L: Up to 160 virtual servers (10 x 16 cores)
p260: Up to 160 virtual servers (10 x 16 cores)
p460: Up to 320 virtual servers (10 x 32 cores)
