Table 1-1 lists the maximum number of compute nodes installed in the chassis.
The actual number of compute nodes that can be installed depends on factors such as the
number and capacity of the power supplies used, the power policy activated, and the TDP
rating of the processors installed in the compute nodes. See 1.6, “Chassis power supplies” on
page 17 for details.

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.
b. One Flex System Manager management node can manage up to 16 chassis

1.2 Switch to adapter interoperability
In this section, we describe switch to adapter interoperability.

1.2.1 Ethernet switches and adapters
Table 1-2 lists Ethernet switch to card compatibility.
Switch upgrades: To maximize the usable port count on the adapters, the switches may
need additional license upgrades. See 1.4, “Switch upgrades” on page 10 for details.

1.4.1 IBM Flex System EN4023 10Gb Scalable Switch
The EN4023 10Gb Scalable Switch comes standard with 24 ports licenses. These licenses
can be applied to any internal or external 10 Gb port. The 40 Gb uplinks are not enabled in
the base switch.
Port upgrades are as follows:
94Y5158 (Upgrade 1) can be applied on the base switch or on top of Upgrade 2 to enable
16 additional 10 GbE ports (internal and external). The upgrade also enables two 40 Gb
uplinks with QSFP+ connectors.
94Y5159 (Upgrade 2) can be applied on the base switch or on top of Upgrade 1 to enable
16 additional 10 GbE ports (internal and external).
Table 1-8 lists the upgrades. These are Features on Demand (FoD) upgrades.

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.

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

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.

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.

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)

1.4.6 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.
This switch ships standard with quad data rate (QDR) and can be upgraded to fourteen data

2.3.3 Power Systems compute nodes
Local storage options for Power Systems compute nodes are shown in Table 2-8. None of the
available drives are hot-swappable. The local drives (HDD or SDD) are mounted to the top
cover of the system. If you use local drives, you must order the appropriate cover with
connections for your wanted drive type as listed in Table 2-9 on page 32. The maximum
number of drives that can be installed in any Power Systems compute node is two. SSD and
HDD drives cannot be mixed.

2.4 Embedded virtualization
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.
There are two types of USB keys, preloaded keys or blank keys. Blank keys allow you to
download an IBM customized version of ESXi and load it onto the key. The x86 compute
nodes (including each of the servers in the x222) support one or two keys installed, but only
certain combinations:
Supported combinations:
One preload key
One blank key
One preload key and one blank key
Two blank keys
Unsupported combinations:
Two preload keys
Installing two preloaded keys will prevent ESXi from booting as described in
http://kb.vmware.com/kb/1035107. Having two keys installed provides a backup boot device.
both devices are listed in the boot menu, which allows you to boot from either device or to set
one as a backup in case the first one gets corrupted.

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 or 20 times the number of cores in the
compute node depending on the server:
p24L: Up to 160 virtual servers (10 x 16 cores)
p260: Up to 160 virtual servers (10 x 16 cores)

directly on Compute Node.
d. Features on Demand (software) upgrade to enable FCoE and iSCSI on the CN4054 and CN4054. One upgrade
needed per adapter.

2.5.3 PCIe I/O adapters - PCIe Expansion Node
The PCIe Expansion Node supports for up to four standard PCIe 2.0 adapters:
Two PCIe 2.0 x16 slots that support full-length, full-height adapters (1x, 2x, 4x, 8x, and
16x adapters supported)
Two PCIe 2.0 x8 slots that support low-profile adapters (1x, 2x, 4x, and 8x adapters
supported)
Storage Expansion Node: The Storage Expansion Node does not include connectors for
PCIe I/O adapters.
Table 2-13 on page 36 lists the supported adapters. Some adapters must be installed in one
of the full-height slots as noted. Some adapters, such as the NVIDIA Tesla M2090, are
double-slot adapters, meaning that another adapter cannot be installed in the other full-height
slot. The low-profile slots and Flex System I/O expansion slots can still be used, however.

c. Orderable as separate MTM 4765-001 feature 4809. Available via AAS (e-config) only.

Consult the IBM ServerProven® site for the current list of adapter cards that are supported in
the Expansion Node:
http://ibm.com/systems/info/x86servers/serverproven/compat/us/flexsystems.html
Note: Although the design of Expansion Node allows for a much greater set of standard PCIe
adapter cards, the preceding table lists the adapters that are specifically supported. If the PCI
Express adapter that you require is not on the ServerProven web site, use the IBM
ServerProven Opportunity Request for Evaluation (SPORE) process to confirm compatibility
in the desired configuration.

2.5.4 Internal storage - Storage Expansion Node
The Storage Expansion Node adds 12 drive bays to the attached compute node. The
expansion node supports 2.5-inch drives, either HDDs or SSDs.
PCIe Expansion Node: The PCIe Expansion Node does not support any drives.
Table 2-14 on page 37 shows the hard disk drives and solid state drives supported within the
Storage Expansion Node. Both SSD and HDD can be installed inside the unit at the same
time, although as per best practice it is recommended that logical drives are created of similar
type of disks. ie for a RAID 1 pair, choose identical drive types, SSD or HDD.

removable media types. The AIX operating system does not support using a USB device as a target for an AIX
operating system installation. The AIX operating system and VIOS only support writing to DVD-RAM media, but
can read all optical media formats through the read interface of the device driver.
b. Only USB tape drives and USB DVD-RAM drives can be virtual devices in a client partition. For all other USB
devices, the USB controller must be assigned to a partition for the partition to have access to the USB device.
