Key features
The Flex System Enterprise Chassis is a simple, integrated infrastructure platform that supports a mix of
compute, storage, and networking resources to meet the demands of your applications. The solution is
easily scalable with the addition of another chassis with the required nodes. With Lenovo XClarity
Administrator, multiple chassis can be monitored from a single screen. This flexible 14 node, 10U chassis
is designed for a simple deployment now and to scale to meet your needs in the future.
Flexibility and efficiency
The 14 bays in the chassis allow the installation of compute or management nodes, with networking
modules in the rear. A single chassis or a group of chassis can be fully customized to the specific needs of
the computing environment. IT can meet the needs of the business using a single system across multiple
operating environments.
The system monitors and manages power usage on all major chassis components so you have total
control over power consumption. Available power supply options are AC and -48V DC. AC power options
can be configurable in either a single or three-phase power domain. The chassis supports N+N or N+1
redundant power supplies and an entirely passive mid-plane to meet your reliability needs. The power
supplies are 80 PLUS Platinum-certified indicating high energy efficiency. The chassis design also
optimizes cooling with cooling zones within the chassis. The system manages the fan modules based on
node configuration within the chassis. So, the system can increase the speed of certain fan modules to
cool potential hot spots, and use lower speeds for other fan modules where appropriate.
Easily scalable with simple administration
Because the Flex System Enterprise Chassis is an all-in-one solution, it is designed for growth from a
single chassis to many. Adding compute, storage, or networking capability is as simple as adding
additional nodes or modules. The simple, highly integrated management system allows you to use the
Chassis Management Modules integrated into each chassis to administer a single chassis, and the new
Lenovo XClarity Administrator offers agent-free hardware management for compute nodes and
networking.
Designed for multiple generations of technology
The Flex System Enterprise Chassis is designed to be the foundation of your IT infrastructure now and into
the future. Compute performance requirements are always on the rise and networking demands continue
to grow with rising bandwidth needs and a shrinking tolerance for latency. The chassis is designed to
scale to meet the needs of your future workloads, offering the flexibility to support current and future
innovations in compute, storage, and networking technology.

* The maximum number of compute nodes supported depends on a number of factors. See below.
** A single Flex System Manager appliance can manage up to 16 chassis
The actual number of compute nodes systems that can be powered on in a chassis depends on these
factors:
The TDP power rating for the processors that are installed in the compute nodes (x86 servers)
The number of power supplies installed in the chassis
The capacity of the power supplies installed in the chassis (2100 W or 2500 W)
The power redundancy policy used in the chassis (N+1 or N+N)
For the x480 X6 or x880 X6, if two compute nodes are scaled together, then a maximum of 3 scaled
complexes can be installed. For the x880 X6, if four compute nodes are scaled together, then a maximum
of 1 scaled x880 X6 complexes can be installed. Other bays can be filled with other compute nodes.
Flex System Enterprise Chassis

The table in the Power Supplies section provides guidelines about what number of compute nodes can be
powered on in the Enterprise Chassis, based on the type and number of power supplies installed.
See ServerProven® for the latest information about the supported servers:
http://www.lenovo.com/us/en/serverproven/flexsystem.shtml
Supported I/O modules
The Flex System Enterprise Chassis has four high-speed switch bays that are capable of supporting a
variety of I/O architectures.
The switches are installed in switch bays in the rear of the Flex System Enterprise Chassis as shown in the
following figure. Switches are normally installed in pairs (bays 1 & 2, and bays 3 & 4), because I/O adapter
cards installed in the compute nodes route to two switch bays for performance and redundancy.

I/O architecture
Each half-wide compute node (such as the Flex System x240 Compute Node) has two adapter slots, and
each full-wide compute node (such as the Flex System x440 Compute Node) has four adapter slots. The
adapter slots in each compute node route through the chassis midplane to the switch bays. The
architecture supports up to eight ports per adapter although currently only two-port and four-port
adapters are available.
The following figure shows how two-port adapters are connected to switches installed in the chassis.
Figure 5. Logical layout of the interconnects between two-port I/O adapters and I/O modules
A four-port adapter doubles the connections between each adapter and switch pair (for example, a fourport adapter in A1 in each compute node routes two connections to switch 1 and two connections to
switch 2).
The following figure shows how four-port adapters are connected to switches that are installed in the
chassis.

* To make use of all four ports of a four-port adapter, the switch must have 28 internal ports enabled, and
two switches must be installed in the bays as indicated.
Chassis Management Module
The Chassis Management Module (CMM) provides single-chassis management in the Enterprise Chassis.
The CMM is used to communicate with the integrated management module (IMM) controller in each
compute node to provide system monitoring, event recording and alerts, and to manage the chassis, its
devices, and the compute nodes.
The chassis has one CMM installed standard but supports two CMMs for redundancy. If one CMM fails,
the second CMM can detect its inactivity and activate itself to take control of the system without any
disruption. The CMM is central to the management of the chassis and is required in the Enterprise
Chassis.
There are two versions of the Chassis Management Module available:
Chassis Management Module 2 (00FJ669) -- contains a Trusted Platform Module (TPM) v2.0 chip
and has a Lenovo-signed firmware codebase. This module is recommended for new installation.
First generation Chassis Management Module (68Y7030) -- contains a Trusted Platform Module
(TPM) v1.1 chip and has an IBM-signed firmware codebase
Standard and TopSeller models of the chassis contain either a CMM (68Y7030) or a CMM2 (00FJ669) as
listed in Table 2. The selection of CMM determines which compute nodes and I/O modules are supported
in the chassis. See Tables 3 and 4 respectively for details. You can replace a CMM with a CMM2, however
mixing is not supported -- you cannot have a chassis with one CMM (68Y7030) and one CMM2 (00FJ669).
The following table shows the ordering information.

Switch management
Diagnostics: chassis, I/O options, and compute nodes
Resource discovery and inventory management
Resource alerts and monitoring management
Chassis and compute node power management
Security policy management
Role-based access control
Support for up to 84 local CMM user accounts
Support for up to 32 simultaneous sessions
The CMM has the following connectors:
USB connection. This connection can be used for insertion of a USB media key for tasks, such as
firmware updates.
10/100/1000 Mbps RJ45 Ethernet connection to connect to a management network. The CMM can
be managed via this Ethernet port.
Serial port (mini-USB) for local command-line interface (CLI) management. Use serial cable 90Y9338
for connectivity.
The CMM has the following light-emitting diodes (LEDs) that provide the following information:
Power-on LED
Activity LED
Error LED
Ethernet port link and port activity LEDs
Flex System Enterprise Chassis
12
The CMM also incorporates a reset button, which, when pressed, resets the CMM back to its default
condition. It has two functions, depending on how long the button is pressed:
When pressed for less than 5 seconds, the CMM restarts.
When pressed for more than 5 seconds (for example, 10 or 15 seconds), the CMM configuration is
reset to the manufacturing defaults, and then the CMM restarts.
The CMM supports a web-based graphical user interface (GUI) that provides a way to perform CMM
functions within a supported web browser. You can also perform management functions through the CMM
command-line interface (CLI). Both the web-based GUI and the CLI are accessible via the single RJ45
Ethernet connector on the CMM or from any other system that is connected to the same (management)
network.
The CMM has the following default static IPv4 address. By default, the CMM is configured to respond to
Dynamic Host Configuration Protocol (DHCP) first before using its static IPv4 address:
IP address: 192.168.70.100
Subnet: 255.255.255.0
User ID: USERID (all capital letters)
Password: PASSW0RD (all capital letters, with a zero instead of the letter O)
The CMM does not have a fixed static IPv6 IP address, by default. Initial access to the CMM in an IPv6
environment can be performed by either using the IPv4 IP address or the IPv6 link-local address. The IPv6
link-local address is automatically generated based on the Media Access Control (MAC) address of the
CMM.
The CMM is the key component enabling the integrated management network. Internally, the CMM has a
multiple port L2 1Gigabit Ethernet switch with dedicated links to all 14 node bays, all four switch bays, and
the second CMM, if installed. These connections are all point-to-point, ensuring dedicated bandwidth. The
1GbE links are full-duplex, fixed speed (not auto-negotiate) links. The 1 GbE management network is only
accessible by each node's management controller (IMMv2 or FSP), each switch module's management
interfaces, the CMM, and the Flex System Manager (FSM) management appliance. This design permits the
separation of the management network from the data network.
The CMM has a high-security policy that is enabled by default, which means that the following policies are
enabled by default:
Strong password policies with automatic validation and verification checks
Required update of the default passwords after the initial setup
Only secure communication protocols, such as SSH and SSL. Unencrypted protocols, such as
HTTP, Telnet, and SNMPv1, are disabled.
Certificates to establish secure, trusted connections for applications that run on the management
processors

The following figure shows the power supply and highlights the light-emitting diodes (LEDs).
Figure 9. Power supply option
The AC power supplies are 80 PLUS Platinum-certified. The 2500W modules are 2500 Watts output rated
at 200VAC to 208VAC (nominal), and 2750W at 220VAC to 240VAC (nominal). The power supply has an
oversubscription rating of up to 3538 Watts output at 200VAC. The power supply operating range is 200240 VAC. The power supplies also contain two dual independently powered 40mm cooling fan modules
that are powered not from the power supply itself, but from the chassis midplane. The fan modules are
variable speed and controlled by the chassis fan logic.
80 PLUS is a performance specification for power supplies used within servers and computers. To meet
the 80 PLUS standard, the power supply must have an efficiency of 80% or greater, at 20%, 50%, and
100% of rated load with PF of .09 or greater. The standard has several grades, such as Bronze, Silver,
Gold, and Platinum. More information on 80 PLUS is available at http://www.80PLUS.org
Flex System Enterprise Chassis

The chassis allows configurations of power supplies to give N+N or N+1 redundancy. A chassis can
operate on only three power-supply units (PSUs) with no redundancy, but N+1 or N+N is advised. Three
power supplies (or six with N+N redundancy) allow for a balanced three-phase configuration.
All power supply modules are combined into a single power domain within the chassis, which distributes
power to each of the compute nodes, I/O modules, and ancillary components through the Enterprise
Chassis midplane. The midplane is a highly reliable design with no active components. Each power supply
is designed to provide fault isolation and is hot swappable.
In the case of the 2500W supplies, power monitoring of both the DC and AC signals allows the Chassis
Management Module to accurately monitor the power supplies.
The following figure shows the compute node bay numbering (left) and power supply bay numbering
(right).
Figure 10. Power supply bay numbering
The following table shows the number of compute nodes that are supported in the chassis based on the
power supplies used (2100W or 2500W), the number of power supplies installed, and the power
redundancy policy enabled (N+1 or N+N).
Note: 2100W power supplies are now withdrawn from marketing.
In this table, the colors of the cells have the following meaning:
Green cell: Supported with no restrictions as to the number of compute nodes that can be installed
Yellow cell: Supported but with restrictions on the number of compute nodes that can be installed.
Note: These tables assume the chassis is filled with idential compute nodes. For more complex
configurations, use the Power Configurator:

Fan modules
The Enterprise Chassis supports up to a total of ten hot-swap fan modules: two 40 mm (1.57 in) fan
modules and eight 80 mm (3.14 in) fan modules.
The two 40 mm fan modules distribute airflow to the I/O modules and chassis management modules. Both
of these fan modules ship with the chassis. The 80 mm fan modules distribute airflow to the compute
nodes through the chassis from front to rear. Each 80 mm fan module actually contains two 80 mm fan
modules, back to back at each end of the module, which are counter-rotating. The following figure shows
the 80 mm fan module.
Figure 11. 80 mm fan module
Four 80 mm fan modules are installed standard in chassis model 8721-A1x and CTO orders. The
maximum number of 80 mm fan modules that can be installed is eight. Ordering information is shown in
the following table. When the modules are ordered as a part number, they are supplied as a pair. The
feature codes is comprised of one fan.

The 80 mm fan modules are populated, depending on the nodes installed. To support the base
configuration and up to four nodes, chassis model 8721-A1x ships with four 80 mm fan modules and two
40 mm fan modules preinstalled. There are two cooling zones for the nodes: a left zone and a right zone.
Fan modules must be installed in pairs as shown in the following figure. If there are insufficient fan
modules for the number of nodes installed, the compute nodes might be throttled to balance heat
generation and cooling capacity.

Power planning for an Flex System Enterprise Chassis is essential.
The Enterprise Chassis has a maximum of six power supplies installed. So, careful consideration must be
given to providing the best power-optimized source. Both N+N and N+1 configurations are supported for
maximum flexibility in power redundancy. Each AC power supply in the chassis has a 16A C20 three-pin
socket and can be fed by a C19 power cable, from a suitable supply.
The chassis has the ability to accommodate a maximum of six power supplies, so it is possible to balance
a three-phase power input into a single chassis or a group of chassis. The chassis power system is
designed for efficiency using data center power consisting of three-phase, 60A Delta 200 VAC (North
America) or three-phase 32A wye 380-415 VAC (international). The chassis can also be fed from singlephase 200 - 240VAC supplies, if required.
