platform for general business workloads. This section describes the key features of the server.
Scalability and performance
The x220 offers numerous features to boost performance, improve scalability, and reduce costs:
The Intel Xeon processor E5-2400 product family improves productivity by offering affordable dual-socket
system performance with eight-core processors with up to 2.3 GHz core speeds, up to 20 MB of L3 cache,
and one QPI interconnect link of up to 8 GTps.
Up to two processors, 16 cores total, and 32 threads maximize the concurrent execution of multithreaded
applications.
Intelligent and adaptive system performance with Intel Turbo Boost Technology 2.0 allows processor cores
to run at maximum speeds during peak workloads by temporarily going beyond processor Thermal Design
Power (TDP).
Intel Hyper-Threading Technology boosts performance for multithreaded applications by enabling
simultaneous multithreading within each processor core, up to two threads per core.
Intel Virtualization Technology integrates hardware-level virtualization hooks that allow operating system
vendors to better use the hardware for virtualization workloads.
Intel Advanced Vector Extensions (AVT) improve floating point performance for compute-intensive technical
and scientific applications compared to Intel Xeon 5600 series processors.
There are 12 DIMM sockets supporting low profile (LP) RDIMMs, UDIMMs and LRDIMMs, with a total
capacity of up 384 GB using 32 GB LRDIMMs
Supports memory speeds of up to 1600 MHz to maximize memory performance.
Support for 1.8-inch solid-state drives to maximize I/O operations per second (IOPS) and significantly
improve application performance.
Supports the Storage Expansion Node providing an additional 12 hot-swap 2.5-inch drive bays for local
storage.
The theoretical maximum memory bandwidth of the Intel Xeon processor E5-2400 product family is 38.4
GBps, which is 20% more than in the previous generation of Intel Xeon 5600 processors.
The server offers PCI Express 3.0 I/O expansion capabilities that improve the theoretical maximum
bandwidth by 60% (8 GTps per link) compared to the previous generation of PCI Express 2.0.
With Intel Integrated I/O Technology, the PCI Express 3.0 controller is integrated into the Intel Xeon
processor E5 family. This integration reduces I/O latency and increases overall system performance.
Support for high-bandwidth I/O adapters, up to two in each x220 Compute Node. Support for 10 Gb
Ethernet, 16 Gb Fibre Channel, and FDR InfiniBand expansion cards.
Supports the PCIe Expansion Node for support for up to six additional I/O adapters.
Availability and serviceability
The x220 provides many features to simplify serviceability and increase system uptime:
Chipkill, memory mirroring, and memory rank sparing for redundancy in the event of a non-correctable
memory failure.
Tool-less cover removal provides easy access to upgrades and serviceable parts, such as processor,
memory, and adapter cards.
Hot-swap drives supporting integrated RAID 1 redundancy for data protection and greater system uptime.
A light path diagnostics panel and individual light path LEDs lead the technician to failed (or failing)
components. These features simplify servicing, speeds up problem resolution, and helps improve system
availability.
Predictive Failure Analysis (PFA) detects when system components (such as processors, memory, and hard
disk drives) operate outside of standard thresholds and generates proactive alerts in advance of possible
failure, therefore increasing uptime.

2
Solid-state drives (SSDs), which offer significantly better reliability than traditional mechanical HDDs for
greater uptime.
A built-in Integrated Management Module II (IMM2) continuously monitors system parameters, triggers alerts,
and performs recovery actions in case of failures to minimize downtime.
Built-in diagnostics using Dynamic Systems Analysis (DSA) Preboot speeds up troubleshooting tasks to
reduce service time.
Three-year customer replaceable unit and on-site limited warranty, next business day 9x5. Optional service
upgrades are available.
Manageability and security
Powerful systems management features simplify local and remote management of the x220:
The server includes an Integrated Management Module II (IMM2) to monitor server availability and perform
remote management.
An integrated industry-standard Unified Extensible Firmware Interface (UEFI) enables improved setup,
configuration, and updates, and simplifies error handling.
Integrated Trusted Platform Module (TPM) V 1.2 support enables advanced cryptographic functionality, such
as digital signatures and remote attestation.

address assignments.
Intel Execute Disable Bit functionality can help prevent certain classes of malicious buffer overflow attacks
when combined with a supporting operating system.
Intel Trusted Execution Technology provides enhanced security through hardware-based resistance to
malicious software attacks, allowing an application to run in its own isolated space protected from all other
software running on a system.
Energy efficiency
The x220 offers the following energy-efficiency features to save energy, reduce operational costs, increase energy
availability, and contribute to a green environment:
Component-sharing design of the Flex System chassis provides ultimate power and cooling savings.
The Intel Xeon processor E5-2400 product family offers better performance over the previous generation
while fitting into the same TDP limits.
Intel Intelligent Power Capability powers individual processor elements on and off as needed, to reduce
power draw.
Low-voltage Intel Xeon processors draw less energy to satisfy demands of power and thermally constrained
data centers and telecommunication environments.
Low-voltage 1.35 V DDR3 memory RDIMMs consume 15% less energy than 1.5 V DDR3 RDIMMs.
Solid-state drives (SSDs) consume as much as 80% less power than traditional spinning 2.5-inch HDDs.
The server uses hexagonal ventilation holes, a part of IBM Calibrated Vectored Cooling™ technology.
Hexagonal holes can be grouped more densely than round holes, providing more efficient airflow through the
system.

* The maximum quantity supported is shown for two processors installed. When one processor is installed, the
maximum quantity supported is half of that shown.
The following memory protection technologies are supported:
ECC
Chipkill (for x4-based memory DIMMs; look for "x4" in the DIMM description)
Memory mirroring
Memory sparing
If memory mirroring is used, then DIMMs must be installed in pairs (minimum of one pair per processor), and both
DIMMs in a pair must be identical in type and size.
If memory rank sparing is used, then a minimum of one quad-rank DIMM or two single-rank or dual-rank DIMMs
must be installed per populated channel (the DIMMs do not need to be identical). In rank sparing mode, one rank of
a DIMM in each populated channel is reserved as spare memory. The size of a rank varies depending on the DIMMs
installed.
The following table lists the memory options available for the x220 server. DIMMs can be installed one at a time, but
for performance reasons, install them in sets of three (one for each of the three memory channels).

ServeRAID M5115 configurations and options
The x220 with the addition of the M5115 controller supports 2.5-inch drives or 1.8-inch solid-state drives or
combinations of the two.
At least one hardware kit is required with the ServeRAID M5115 controller, and there are three hardware kits that
are supported that enable specific drive support:
ServeRAID M5100 Series Enablement Kit for Flex System x220 (90Y4424) enables support for up to two 2.5inch HDDs or SSDs in the hot-swap bays in the front of the server. It includes a CacheVault unit, which
enables MegaRAID CacheVault flash cache protection. This enablement kit replaces the standard two-bay
backplane (which is attached through the planar to an onboard controller) with a new backplane that
attaches to an included flex cable to the M5115 controller. It also includes an air baffle, which also serves as
an attachment for the CacheVault unit.
MegaRAID CacheVault flash cache protection uses NAND flash memory powered by a supercapacitor to
protect data stored in the controller cache. This module eliminates the need for a lithium-ion battery
commonly used to protect DRAM cache memory on PCI RAID controllers. To avoid the possibility of data
loss or corruption during a power or server failure, CacheVault technology transfers the contents of the DRAM
cache to NAND flash using power from the supercapacitor. After the power is restored to the RAID controller,
the saved data is transferred from the NAND flash back to the DRAM cache, which can then be flushed to
disk.
ServeRAID M5100 Series SSD Expansion Kit for Flex System x220 (90Y4426) enables support for up to four
internal 1.8-inch SSDs. This kit includes two air baffles, left and right, which can attach two 1.8-inch SSD
attachment locations and flex cables for attachment to up to four 1.8-inch SSDs.
The following table shows the kits required for each combination of drives. For example, if you plan to install eight
1.8-inch SSDs, then you need the M5115 controller, the Flash kit, and the SSD Expansion kit.

I/O path to increase the maximum I/O per second (IOPS) capability of the controller. This feature boosts the
performance of applications with a highly random data storage access pattern, such as transactional
databases. Part number 90Y4412 is an FoD license.
SSD Caching Enabler for traditional hard drives (90Y4447)
The SSD Caching Enabler for Flex System (implemented using the LSI MegaRAID CacheCade Pro 2.0) is
designed to accelerate the performance of hard disk drive (HDD) arrays with only an incremental investment
in solid-state drive (SSD) technology. The feature enables the SSDs to be configured as a dedicated cache to
Flex System x220 Compute Node
14
help maximize the I/O performance for transaction-intensive applications, such as databases and web
serving. The feature tracks data storage access patterns and identifies the most frequently accessed data.
The hot data is then automatically stored on the SSDs that are assigned as a dedicated cache pool on the
ServeRAID controller. Part number 90Y4447 is an FoD license. This feature requires that at least one SSD
drive be installed.
Note: Not all SSDs support SSD Caching Enabler (CacheCade) feature. See

Internal tape drives
The server does not support an internal tape drive. However, it can be attached to external tape drives using Fibre
Channel connectivity.
Optical drives
Flex System x220 Compute Node
17
Optical drives
The server does not support an internal optical drive option, however, you can connect an external USB optical
drive. See http://support.lenovo.com/en/documents/pd011281 for information about available external optical
drives from Lenovo. Alternatively, use the remote media feature of the IMMv2 and the Chassis Management
Module. (Ask dw: Last line applies to Flex Sys only?)
Note: The USB port on the compute nodes supply up to 0.5 A at 5 V. For devices that require more power, an
additional power source will be required.
Embedded 1 Gb Ethernet controller
Some models of the x220 include an Embedded 1 Gb Ethernet controller (also known as LAN on Motherboard or
LOM) built into the system board. Table 2 lists what models of the x220 include the controller. Each x220 model that
includes the controller also has the Compute Node Fabric Connector installed in I/O connector 1 (and physically
screwed onto the system board) to provide connectivity to the Enterprise Chassis midplane. Figure 3 shows the
location of the Fabric Connector.
The Fabric Connector enables port 1 on the controller to be routed to I/O module bay 1 and port 2 to be routed to
I/O module bay 2. The Fabric Connector can be unscrewed and removed, if required, to allow the installation of an
I/O adapter on I/O connector 1.
The Embedded 1 Gb Ethernet controller has the following features:
Broadcom BCM5718 based
Dual-port Gigabit Ethernet controller
PCIe 2.0 x2 host bus interface
Supports Wake on LAN
Supports Serial over LAN
Supports IPv6
Note: TCP/IP Offload Engine (TOE) is not supported.
I/O expansion options
The x220 has two I/O expansion connectors for attaching I/O adapter cards. There is a third expansion connector
designed to connect an expansion node such as the PCIe Expansion Node. The I/O expansion connectors are a
very high-density 216-pin PCIe connector. Installing I/O adapter cards allows the server to connect with switch
modules in the Flex System Enterprise Chassis. Each slot has one PCI Express 3.0 x8 and one PCI Express x4
interface and both slots support the same form-factor adapters.
The following figure shows the location of the I/O expansion connectors.

Figure 6. Location of the I/O adapter slots in the Flex System x220 Compute Node
All I/O adapters are the same shape and can be used in any available slot.. A compatible switch or pass-through
module must be installed in the corresponding I/O bays in the chassis, as indicated in the following table. Installing
two switches means that all ports of the adapter are enabled, which improves performance and network availability.

Network adapters
Flex System x220 Compute Node

Network adapters
As described in "Embedded 1 Gb Ethernet Adapter," certain models have a Embedded 1 Gb Ethernet controller on
the system board, and its ports are routed to the midplane and switches installed in the chassis through a Compute
Note Fabric Connector that takes the place of an adapter in I/O slot 1.
Models without the Embedded 1 Gb Ethernet controller do not include any other Ethernet connections to the
Enterprise Chassis midplane as standard. Therefore, for those models, an I/O adapter must be installed in either I/O
connector 1 or I/O connector 2 to provide network connectivity between the server and the chassis midplane and
ultimately to the network switches.
The following table lists the supported network adapters and upgrades. Adapters can be installed in either slot.
However, compatible switches must be installed in the corresponding bays of the chassis. All adapters can also be
installed in the PCIe Expansion Node.

Integrated virtualization
The x220 supports the ESXi hypervisor on a USB memory key via two internal USB ports (see Figure 3). The
supported USB memory keys are listed in the following table.
There are two types of USB keys, preloaded keys or blank keys. Blank keys allow you to download a Lenovo
customized version of ESXi and load it onto the key. The x220 supports 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.

Light path diagnostics
For quick problem determination when you are physically at the server, the x220 offers a three-step guided path:
1. The Fault LED on the front panel
2. The light path diagnostics panel, shown in the following figure.
3. LEDs next to key components on the system board
The x220 light path diagnostics panel is visible when you remove the server from the chassis. The panel is located
at the upper right side of the compute node, as shown in the following figure.
Figure 10. Location of x220 light path diagnostics panel
To illuminate the light path diagnostics LEDs, power off the compute node, slide it out of the chassis, and press the
power button. The power button doubles as the light path diagnostics remind button when the server is removed
from the chassis.
The meanings of the LEDs in the light path diagnostics panel are listed in the following table.
Table 20. Light path diagnostic panel LEDs
