I BM ® IBM Flex System X6 Compute Nodes Product Guide IBM Redbooks Product Guide The IBM® Flex System X6 Compute Node family, composed of the x880 X6, x480 X6, and x280 X6, are high-performance scalable compute nodes that are designed to take on the most demanding workloads. The performance, flexibility, and resiliency features enable the X6 to run mission-critical workloads, such as key business applications, database, analytics, and large virtual machine deployments.
Key features The increasing demand for cloud-computing and analytics workloads by enterprises to meet social, mobile, and big data requirements drives innovation to find new ways to build informational systems. Clients are looking for cost-optimized and fit-for-purpose IT solutions that manage large amounts of data, easily scale performance, and provide enterprise class reliability.
PCI Express 3.0 I/O adapter slots that improve the theoretical maximum bandwidth by almost 100% (8 GTps per link using 128b/130b encoding) compared to the previous generation of PCI Express 2.0 (5 GTps per link using 8b/10b encoding). With Intel Integrated I/O Technology, the PCI Express 3.0 controller is integrated into the Intel Xeon processor E7 v2 product families. This integration helps reduce I/O latency and increase overall system performance.
Flex System Enterprise Chassis-based hot-swap power supplies and hot-swap dual-motor redundant fans provide availability for mission-critical applications. A light path diagnostics panel and individual light path LEDs quickly lead the technician to failed (or failing) components. This panel simplifies servicing, speeds up problem resolution, and helps improve system availability.
Locations of key components and connectors Figure 2 shows the front of the server and Figure 3 shows the inside of the server. Figure 2. Front view of the IBM Flex System X6 Compute Node Figure 3.
The following figure shows how four x880 Compute Nodes can be connected together to form a single 8-socket complex. Note this is for illustrative purposes only; in a production environment, you first install the compute nodes in the chassis and then attach the scalability connector to all four nodes. Figure 4.

Chassis support The X6 Compute Nodes are supported in the IBM Flex System Enterprise Chassis. Up to seven X6 compute nodes can be installed in the chassis in 10U of rack space.
Scalability The X6 compute nodes can scale to a 4-socket or 8-socket complex depending on the processor that is installed into the node: An x880 X6 node with Intel Xeon E7-8800 v2 family processors can scale up to an 8-socket configuration, and supports 2-socket, 4-socket, and 8-socket configurations. All the processors in these 2-socket, 4-socket, and 8-socket configurations must be identical.
Processor options The X6 compute nodes support the processor options that are listed in the following table. The server supports two Intel Xeon E7-2800 v2, E7-4800 v2, or E7-8800 v2 processors depending on model. The table also shows which server models have each processor standard. If no corresponding model for a particular processor is listed, the processor is available only through the configure-to-order (CTO) process. No part numbers: All Flex System X6 Compute Nodes have two processors as a standard.
Memory options IBM DDR3 memory is compatibility tested and tuned for optimal performance and throughput. IBM memory specifications are integrated into the light path diagnostic tests 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.
When RDIMMs are installed, the maximum number of ranks that are supported per channel is eight. With LRDIMMs, the rank count per channel can be 32 (LRDIMM ranks are only 25% of the electrical load of an RDIMM rank). All DIMMs in all processor memory channels operate at the same speed, which is determined as the lowest value of the following components: o o o The memory mode used: Performance (independent) mode or RAS (lockstep) mode. Memory speed that is supported by a specific processor.
The following memory protection technologies are supported: ECC Chipkill (for x4-based memory DIMMs) Redundant bit steering (Double Device Data Correction) Memory mirroring Memory rank sparing Chipkill and Redundant Bit Steering are supported in RAS mode. Chipkill is supported in Performance mode. If memory mirroring is used, DIMMs must be installed in pairs for Performance mode (minimum of one pair per each processor) and quads for RAS mode.
Internal drive options The 2.5-inch drive bays support SAS or SATA HDDs or SATA SSDs. The following table lists the supported 2.5-inch drive options. Table 9. 2.5-inch drive options for internal disk storage (Part 1 of 2) Part number Feature code Description Maximum supported 10K SAS hard disk drives 00AJ146 A4TP IBM 1.2TB 10K 6Gbps SAS 2.5'' G3HS HDD 2 00AJ071 A4TN IBM 900GB 10K 6Gbps SAS 2.5" SFF G3HS HDD 2 00AJ091 A4TM IBM 600GB 10K 6Gbps SAS 2.

I/O expansion options The X6 compute node has four I/O expansion connectors for attaching I/O adapters, as shown in the following figure. Installing I/O adapters allows the server to connect to switch modules in the IBM Flex System Enterprise Chassis. The following figure shows the location of the four I/O expansion slots. Note: Slots 3 and 4 support only a subset of the adapters that are supported in slots 1 and 2.
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 the ports of the adapter are enabled, which improves performance and network availability. Table 10.
The following figure shows the location of the switch bays in the IBM Flex System Enterprise Chassis. Figure 8. Location of the switch bays in the IBM Flex System Enterprise Chassis The following figure shows how 2-port adapters are connected to switches that are installed in the chassis. Figure 9.
Network adapters An Ethernet adapter must be installed in slot 1 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 and the slots they are each supported in. Compatible switches must be installed in the corresponding bays of the chassis.
Storage host bus adapters The following table lists the storage host bus adapters (HBAs) that are supported by the compute node. Note: The following adapter with two ASICs is not supported in slots 3 and 4: IBM Flex System FC5054 4-port 16Gb FC adapter Table 12.
Integrated virtualization The X6 compute node supports the ESXi hypervisor on a USB memory key through 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: preinstalled keys or blank keys. Blank keys allow you to download an IBM customized version of ESXi and load it onto the key.
Light path diagnostics panel For quick problem determination when you are physically at the server, the compute node offers a 3-step guided path: 1. The Fault LED on the front panel 2. The light path diagnostics panel 3. LEDs next to key components on the system board The light path diagnostics panel is visible when you remove the server from the chassis. The panel is at the upper right side of the compute node, as shown in the following figure. Figure 10.
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 two components 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.
Note: Support by some of these operating system versions will be after the date of initial availability. For the latest information about the specific versions and service levels that are supported and any other prerequisites, see the IBM ServerProven® website at: http://www.ibm.com/systems/info/x86servers/serverproven/compat/us/nos/matrix.shtml Physical specifications Dimensions and weight (approximate) for one X6 compute node: Width: 435 mm (17.1 in.) Height 56 mm (2.1 in.) Depth 500 mm (19.
