Key features

The IBM Flex System x220 Compute Node is a high-availability, scalable compute node optimized to support the next-generation microprocessor technology. With a balance between cost and system features, the x220 is an ideal 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.
  • 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:

Memory options

IBM DDR3 memory is compatibility tested and tuned for optimal performance and throughput. IBM memory specifications are integrated into the light path diagnostics for immediate system performance feedback and optimum system uptime. From a service and support standpoint, IBM memory automatically assumes the IBM system warranty, and IBM provides service and support worldwide.

The x220 supports Low Profile (LP) DDR3 memory RDIMMs, UDIMMs and LRDIMMs. The server supports up to six DIMMs when one processor is installed and up to 12 DIMMs when two processors are installed. Each processor has three memory channels, and there are two DIMMs per channel.

The following rules apply when selecting the memory configuration:

  • Mixing 1.5 V and 1.35 V DIMMs in the same server is supported, but all DIMMs operate at 1.5 V.
  • The maximum number of ranks supported per channel is eight.
  • The maximum quantity of DIMMs that can be installed in the server depends on the number of processors, as shown in the "Max. qty supported" row in the following table.
  • All DIMMs in all processor memory channels operate at the same speed, which is determined as the lowest value of:
    • Memory speed supported by a specific processor.
    • Lowest maximum operating speed for the selected memory configuration that depends on rated speed, as shown under the "Max. operating speed" section in the following table. The shaded cells indicate that the speed indicated is the maximum that the DIMM allows.

The following table shows the maximum memory speeds that are achievable based on the installed DIMMs and the number of DIMMs per channel. The table also shows maximum memory capacity at any speed supported by the DIMM and maximum memory capacity at rated DIMM speed. In the table, cells highlighted with a grey background indicate when the specific combination of DIMM voltage and number of DIMMs per channel still allows the DIMMs to operate at rated speed.

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 IBM Flex System x220 (90Y4424) enables support for up to two 2.5-inch 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.

    Tip: The Enablement Kit is only required if 2.5-inch drives are to be used. If you plan to install four or eight 1.8-inch SSDs only, then this kit is not required.

  • ServeRAID M5100 Series IBM Flash Kit for IBM Flex System x220 (90Y4425) enables support for up to four 1.8-inch SSDs. This kit replaces the standard two-bay backplane with a four-bay SSD backplane that attaches to an included flex cable to the M5115 controller. Because only SSDs are supported, a CacheVault unit is not required, and therefore this kit does not have a supercapacitor.
  • ServeRAID M5100 Series SSD Expansion Kit for IBM 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.

These features are described as follows:
  • RAID 6 Upgrade (90Y4410)

    Adds support for RAID 6 and RAID 60. This is a Feature on Demand license.

  • Performance Upgrade (90Y4412)

    The Performance Upgrade for IBM Flex System (implemented using the LSI MegaRAID FastPath software) provides high-performance I/O acceleration for SSD-based virtual drives by using an extremely low-latency 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 a Feature on Demand license.

  • SSD Caching Enabler for traditional hard drives (90Y4447)

    The SSD Caching Enabler for IBM 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 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 a Feature on Demand license. This feature requires that at least one SSD drive be installed.

    Note: Not all SSDs support SSD Caching Enabler (CacheCade) feature. See http://ibm.com/support/entry/portal/docdisplay?lndocid=MIGR-5094754 for details.

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

The server does not support an internal optical drive option. However, you can connect an external USB optical drive, such as the IBM and Lenovo part number 73P4515 or 73P4516, or use the remote media feature of the IMMv2 and the Chassis Management Module.

Note: The USB port on the compute node supplies 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 IBM 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.

Location of the I/O adapter slots in the IBM Flex System x220 Compute Node
Figure 7. Location of the I/O adapter slots in the IBM 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

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.

Power supplies

Server power is derived from the power supplies installed in the chassis. There are no server options regarding power supplies.

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 an IBM 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.

Location of x220 light path diagnostics panel
Figure 11. 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 19. Light path diagnostic panel LEDs
LEDMeaning
LPThe light path diagnostics panel is operational.
S BRDA system board error is detected.
MISA mismatch has occurred between the processors, DIMMs, or HDDs within the configuration (as reported by POST).
NMIA non-maskable interrupt (NMI) has occurred.
TEMPAn over-temperature condition occurs that was critical enough to shut down the server.
MEMA memory fault has occurred. The corresponding DIMM error LEDs on the system board are also lit.
ADJA fault is detected in the adjacent expansion unit (if installed).

Remote management

The server contains an IBM Integrated Management Module II (IMM2), which interfaces with the advanced management module in the chassis. The combination of these features provides advanced service-processor control, monitoring, and an alerting function. If an environmental condition exceeds a threshold or if a system component fails, LEDs on the system board are lit to help you diagnose the problem, the error is recorded in the event log, and you are alerted to the problem. A virtual presence capability comes standard for remote server management.

Remote server management is provided through industry-standard interfaces:

  • Intelligent Platform Management Interface (IPMI) Version 2.0
  • Simple Network Management Protocol (SNMP) Version 3
  • Common Information Model (CIM)
  • Web browser

The server also supports virtual media and remote control features, which provide the following functions:
  • Remotely viewing video with graphics resolutions up to 1600x1200 at 75 Hz with up to 23 bits per pixel, regardless of the system state
  • Remotely accessing the server using the keyboard and mouse from a remote client
  • Mapping the CD or DVD drive, diskette drive, and USB flash drive on a remote client, and mapping ISO and diskette image files as virtual drives that are available for use by the server
  • Uploading a diskette image to the IMM2 memory and mapping it to the server as a virtual drive
  • Capturing blue-screen errors
