Introduction

IBM® NeXtScale System is a new HPC offering from IBM. This new dense offering is based on our experience with IBM iDataPlex® and IBM BladeCenter® along with a tight focus on emerging and future client requirements. The IBM NeXtScale n1200 enclosure and IBM NeXtScale nx360 M4 server are designed to optimize density and performance within typical data center infrastructure limits. The 6U NeXtScale n1200 enclosure fits in a standard 19-inch rack and up to twelve nx360 M4 servers can be installed into the enclosure. With more computing power per watt and the latest Intel Xeon processors, you can reduce costs while maintaining speed and availability.

Suggested use: Technical computing, grid deployments, analytics workloads, and large-scale cloud and virtualization infrastructures

Did you know?

IBM NeXtScale System is built with industry-standard components to create flexible configurations of servers, chassis, and networking switches that integrate easily in a standard 19-inch rack. It is a general-purpose platform that provides flexibility to clients for creating unique and differentiated solutions using off-the-shelf components. Front-access cabling enables you to quickly and easily make changes in networking, power connections, and storage.

Key features

Introducing IBM NeXtScale System, which is a new generation IBM Intelligent Cluster™ platform that follows on from the highly successful iDataPlex offering.

Designed with industry-standard, off-the-shelf components, IBM NeXtScale System is a general-purpose platform that is designed to give customers a flexible IT infrastructure. The offering initially will be available with compute-intensive systems, but the design allows for a mix-and-match approach, with I/O-rich, storage-rich, and GPU-rich offerings possible. Customized solutions can be configured to provide an application-appropriate platform with a choice of servers, networking switches, adapters, and racks.

This modular system is designed to scale and grow with data center needs to protect and maximize IT investments. Because it is optimized for standard racks, users can easily mix high-density NeXtScale server offerings and non-NeXtScale components within the same rack. IBM NeXtScale System also provides tremendous time to value by enabling users to set up and start it in a shorter period.

The NeXtScale nx360 M4 server provides a dense, flexible solution with a low total cost of ownership (TCO). The half-wide, dual-socket NeXtScale nx360 M4 server is designed for data centers that require high performance but are constrained by floor space. By taking up less physical space in the data center, the NeXtScale server enhances density, and it supports the Intel Xeon E5-2600 v2 series up to 130 W and 12-core processors, thus providing more performance per server. The nx360 M4 compute node contains only essential components in the base architecture to provide a cost-optimized platform. The Storage Native Expansion Tray can be added to the nx360 M4 to form a storage-dense server supporting up to 32 TB of local storage.

The NeXtScale n1200 Enclosure is an efficient, 6U, 12-node chassis with no built-in networking or switching capabilities, and therefore requires no chassis-level management. Sensibly designed to provide shared, high-efficiency power and cooling for housed servers, the n1200 enclosure is designed to scale with your business needs.

Adding compute capability, or later storage or acceleration capability, is as simple as adding specific nodes to the chassis. Because each node is independent and self-sufficient, there is no contention for resources among nodes within the enclosure. A typical rack holds only 42 1U systems, but this chassis doubles the density (up to 84 compute nodes within the same footprint).

Scalability and performance

The IBM NeXtScale System and the NeXtScale nx360 M4 server offer numerous features to boost performance, improve scalability, and reduce costs:

  • Up to 12 compute nodes, each with two of the latest Xeon processors, eight DIMMs, and two PCIe slots, in 6U of rack space. It is a highly dense, scalable, and price-optimized offering.
  • The Intel Xeon processor E5-2600 v2 product family improves productivity by offering superior system performance with 12-core processors and up to 3.0 GHz core speeds, up to 25 MB of L3 cache, and QPI interconnect links of up to 8 GTps.
  • Two processors, up to 24 cores, and 48 threads maximize the concurrent execution of multi-threaded applications.
  • Intelligent and adaptive system performance with Intel Turbo Boost Technology 2.0 allows CPU 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 multi-threaded applications by enabling simultaneous multi-threading 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 (AVX) improve floating-point performance for compute-intensive technical and scientific applications.
  • Eight DIMMs of registered 1866 MHz DDR3 ECC memory provide speed, high availability, and a memory capacity of up to 256 GB.
  • Support for additional local storage with the use of the Storage Native Expansion Tray. When using 4 TB HDDs, you can create an ultra-dense storage server with up to 32 TB of total disk capacity within 1U of comparable rack density. The nx360 M4 with the Storage Native Expansion Tray offers a perfect solution for today’s data-intensive workloads.
  • The use of solid-state drives (SSDs) instead of or with traditional hard disk drives (HDDs) can improve I/O performance. An SSD can support up to 100 times more I/O operations per second (IOPS) than a typical HDD.
  • PCI Express 3.0 I/O expansion capabilities improve the theoretical maximum bandwidth by 60% (8 GTps per link) compared with the previous generation of PCI Express 2.0.
  • There is support for 10 Gb Ethernet and FDR mezzanine cards that offer network performance without consuming a PCIe slot.
  • With Intel Integrated I/O Technology, the PCI Express 3.0 controller is integrated into the Intel Xeon processor E5 family, which reduces I/O latency and increases overall system performance.

Manageability and security

Powerful systems management features simplify local and remote management of the nx360 M4:
  • 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) 1.2 support enables advanced cryptographic functionality, such as digital signatures and remote attestation.
  • IBM Systems Director is included for proactive systems management. It offers comprehensive systems management tools that increase uptime, reduce costs, and improve productivity through advanced server management capabilities.
  • Intel Execute Disable Bit functionality can 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 the application to run in its own isolated space that is protected from all other software running on a system.

Energy efficiency

IBM NeXtScale System offers the following energy efficiency features to save energy, reduce operational costs, increase energy availability, and contribute to a green environment:
  • Support for S3 standy power states in the processor
  • The nx360 M4 is Energy Star 2.0 compliant. Energy Star is the trusted, US government-backed symbol for energy efficiency, with the goal of helping customers save money and protect the environment through energy efficient products and practices. For the Power and Performance Data Sheet, see http://ibm.com/systems/x/hardware/energy-star
  • Shared 80 Plus Platinum power supplies ensure energy efficiency.
  • Large 80 mm fans maximize air flow efficiencies.
  • The Intel Xeon processor E5-2600 v2 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 19% less energy than 1.5 V DDR3 RDIMMs.
  • SSDs consume as much as 80% less power than traditional 2.5-inch HDDs.
  • The server uses hexagonal ventilation holes in the front and rear of the casing, which can be grouped more densely than round holes, providing more efficient airflow through the system.
  • There are power monitoring and power capping capabilities through the Power and Fan Management Module in the chassis

Availability and serviceability

IBM NeXtScale System and the nx360 M4 server provide many features to simplify serviceability and increase system uptime:
  • The NeXtScale n1200 chassis supports N+N and N+1 power policies for its six power supplies, which means greater system uptime.
  • All components can be removed from the front of the rack by sliding out the trays or the chassis for easy, quick servicing.
  • Toolless cover removal provides easy access to upgrades and serviceable parts, such as HDDs and memory.
  • The nx360 M4 offers memory mirroring for redundancy if there is a non-correctable memory failure.
  • Optional RAID arrays enable the server to keep operating if there is a failure of any one drive.
  • SSDs offer better reliability than traditional mechanical HDDs for greater uptime.
  • Predictive Failure Analysis (PFA) detects when system components (processors, memory, and hard disk drives) operate outside of standard thresholds and generates proactive alerts in advance of possible failure, therefore increasing uptime.
  • The built-in Integrated Management Module II (IMM2) continuously monitors system parameters, triggers alerts, and performs recovering actions in case of failures to minimize downtime.
  • The IMM2 offers optional remote management capability to enable remote keyboard, video, and mouse (KVM) control of the server.

Memory options

IBM DDR3 memory is compatibility tested and tuned for optimal IBM System x® 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 NeXtScale nx360 M4 supports DDR3 memory. The server supports up to four DIMMs when one processor is installed and up to eight DIMMs when two processors are installed. Each processor has four memory channels, and there is one DIMM per memory channel (1 DPC). RDIMM, UDIMM and LRDIMM are supported, but the mixing of these different types is not supported.

In the nx360 M4, the maximum memory speed of a configuration is the lower of the following two values:

  • The memory speed of the processor (See Table 4.)
  • The memory speed of the DIMM (See Table 5.)

The server supports both 1.5 V and 1.35 V DIMMs. Mixing 1.5 V and 1.35 V DIMMs in the same server is supported. In such a case, all DIMMs operate at 1.5 V.

The following memory protection technologies are supported:
  • ECC
  • Memory mirroring

The following figure shows the IBM NeXtScale Storage Native Expansion Tray with the cover removed showing seven 3.5-inch drives installed.


Figure 7. IBM NeXtScale Storage Native Expansion Tray

When the Storage Native Expansion Tray is used, one of the following disk controller adapters must be installed in the PCIe slot in the nx360 M4:
  • ServeRAID M1115 SAS/SATA Controller for IBM System x, 81Y4448
  • N2115 SAS/SATA HBA for IBM System x, 46C8988

Internal storage

The NeXtScale nx360 M4 server supports one of the following drives internally in the server:

  • One 3.5-inch simple-swap SATA drive
  • Two 2.5-inch simple-swap SAS or SATA HDDs
  • Four 1.8-inch simple-swap SSDs

In addition, the nx360 M4 supports seven additional 3.5-inch drive bays if the IBM NeXtScale Storage Native Expansion Tray is attached. The Storage Native Expansion Tray can be used with any of the above three internal drive configurations to provide the following bay combinations:
  • Eight 3.5-inch simple-swap SATA drives
  • Seven 3.5-inch simple-swap SATA drives and two 2.5-inch simple-swap SATA HDDs
  • Seven 3.5-inch simple-swap SATA drives and four 1.8-inch simple-swap SSDs

Drive cages for the drives internal to the nx360 M4 are as listed in the following table. Drives used in the Storage Native Expansion Tray do not need a cage.

The following figure shows the three variations (the two 3.5-inch cages look similar).


Figure 8. Drive bay options

There are two 3.5-inch drive cages - the last two rows of the above table. If the Storage Native Expansion Tray is attached to the nx360 M4, then the use of the RAID cage (feature A4GE, option 00Y8615) allows you to configure a RAID array that spans all 8 drives - the 7 in the storage tray and the 1 drive internal to the nx360 M4. Such a configuration would be connected either to a ServeRAID M1115 adapter or N2115 SAS HBA.

If the 3.5-inch HDD cage (feature A41J) is used, then a RAID array can only be formed with the 7 drives in the storage tray. In such a configuration, the drives in the storage tray are connected either to a ServeRAID M1115 adapter or N2115 SAS HBA, and the single drive in the nx360 M4 is connected to the ServeRAID C100.

Controllers for internal storage

The following table lists the RAID controllers and SAS HBA that are used for internal disk storage of the nx360 M4 server. These are alternatives to the onboard SATA controller and one may be required depending on the storage configuration.

† Requires the 3.5-inch RAID cage (feature A4GE, option 00Y8615)

Using the ServeRAID C100 with 1.8-inch SSDs

The on-board ServeRAID C100 SATA controller provides four channels, two at 3 Gbps and two at 6 Gbps. These connect to the four 1.8-inch drive bays in the nx360 M4. When installing only two 1.8-inch drives, install them in the top two drive bays to maximize performance, since the top two bays are the ones operating at 6 Gbps.

When four 1.8-inch SS SATA SSD drives are installed, the two located at the top of the cage will operate at 6 Gbps while the two at the bottom will operate at 3 Gbps. An array involving drives at different speeds, will perform at the lowest speed. For example, a paired array between top drives will operate at 6 Gbps but, a paired array between a top drive and a bottom, will operate at 3 Gbps.

Controller use in conjunction with the Storage Native Expansion Tray

When the Storage Native Expansion Tray is used one of the following disk controller adapters must be installed in the PCIe slot in the nx360 M4.
  • ServeRAID M1115 SAS/SATA Controller for IBM System x, 81Y4448
  • N2115 SAS/SATA HBA for IBM System x, 46C8988

If you are using the ServeRAID M1115 controller and you have a 3.5-inch drive in the internal bay of the nx360 M4, and you wish to be able to form a RAID array with all 8 drives (1 in the server and 7 in the storage tray), then you must use the 3.5-inch RAID cage for the internal drive (feature A4GE, option 00Y8615), replacing the standard 3.5-inch HDD cage if already installed in the server. The 3.5-inch RAID cage includes a backplane that allows the internal drive to be connected to the drives in the storage tray.

If you do not use the 3.5-inch RAID cage or you are using 2.5-inch or 1.8-inch drives in the nx360 M4, then the internal drives will be connected to a separate controller than the drives in the storage tray and you will not be able to form a RAID array spanning both internal drives and drives in the storage tray. The internal drives are connected to the ServeRAID C100 controller as indicated in the above table.

Note: It is not a supported combination to have the Storage Native Expansion Tray with 7 drives along with two 2.5-inch SAS drives installed in the nx360 M4. This is because the ServeRAID C100 (which would be required to drive the two internal drives) does not support SAS drives. The use of 2.5-inch SATA drives are supported however.

To aid with problem determination, the server includes light path diagnostics, which is a set of LEDs on the front of the server and inside the server that show you which component is failing. The LEDs are shown in the following figure.

Power button and system LEDs
Figure 10. Power button and system LEDs

When an error occurs, the system error LED lights up. Review the logs through the web interface of the IMMv2 (see the "Remote server management" section). If needed, power off the server and remove it from the enclosure. Then, press and hold the power button to activate the system board LEDs. The LED next to the failed component lights up.

Remote server management

The server contains IBM Integrated Management Module II (IMM2), which provides advanced service-processor control, monitoring, and an alerting function. If an environmental condition exceeds a threshold or if a system component fails, the IMM2 lights LEDs to help you diagnose the problem, records the error in the event log, and alerts you to the problem. The server includes IMM2 Basic and can be upgraded to IMM2 Standard and IMM2 Advanced with Feature on Demand (FoD) licenses; however, you might need to upgrade the system firmware to the latest levels (at least level 28n) to support these upgrades.

IMM2 Basic has the following features:

  • Industry-standard interfaces and protocols
  • Intelligent Platform Management Interface (IPMI) Version 2.0
  • Common Information Model (CIM)
  • Advanced Predictive Failure Analysis (PFA) support
  • Continuous health monitoring
  • Shared Ethernet connection
  • Domain Name System (DNS) server support
  • Dynamic Host Configuration Protocol (DHCP) support
  • Embedded Dynamic System Analysis (DSA)
  • LAN over USB for in-band communications to the IMM
  • Serial over LAN
  • Server console serial redirection

IMM2 Standard (as enabled using the Feature on Demand software license key using part number 90Y3900) has the following features in addition to the IMM2 Basic features:
  • Remote access through a secure web console
  • Access to server vital product data (VPD)
  • Automatic notification and alerts
  • Continuous health monitoring and control
  • Email alerts
  • Syslog logging support
  • Enhanced user authority levels
  • Event logs that are time stamped, saved on the IMM, and that can be attached to email alerts
  • OS watchdogs
  • Remote configuration through Advanced Settings Utility (ASU)
  • Remote firmware updating
  • Remote power control
  • User authentication using a secure connection to a Lightweight Directory Access Protocol (LDAP) server

IMM2 Advanced (as enabled using the Feature on Demand software license key using part number 90Y3901) adds the following features on top of those of IMM Standard:
  • Remotely viewing video with graphics resolutions up to 1600x1200 at 75 Hz with up to 23 bits per pixel color depths, 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 IMM memory and mapping it to the server as a virtual drive

The blue-screen capture feature captures the video display contents before the IMM restarts the server when the IMM detects an operating-system hang condition. A system administrator can use the blue-screen capture to assist in determining the cause of the hang condition.

The following table lists the remote management options.

Note: The IMM2 Advanced upgrade requires the IMM2 Standard upgrade.

The nx360 M4 provides a dedicated Ethernet port that allows connection to the IMM2. It is a port to access the IMM2 separately from the onboard two-port 1 Gb Ethernet controller. Alternatively, the first 1 Gb Ethernet port from the onboard controller can be configured in Shared mode in order to allow access to the IMM2. With Shared mode enabled, the dedicated IMM port is disabled.

Remote enclosure management

Fan and Power Controller
Figure 11. Fan and Power Controller

The Fan and Power Controller has one external RJ45 port which provides a 10/100 Mbps Ethernet connection for browser-based remote control.

The port provide the following interfaces:

  • An HTTP (web browser) interface for remote management
  • An IPMI interface to the IMM in each server
  • An IPMI interface to higher managers, such as xCAT

The module provides the following functions:
  • Power supply redundancy and over-subscription configuration
  • Power capping/saving configuration
  • Power restore policy
  • Acoustic mode setting
  • Configuration/log export to USB (a USB port is provided inside the module; see the diagram in Figure 8.)
  • IMM remote reset or Server remote reseat (AC cycle)
  • Status monitor: Power consumption, node status, power supply status, fan status
  • Network configuration

The FPC also includes a USB key housed in side the unit. The USB key stores the event log for the FPC plus power, cooling and network configuration data.
