Key features
The Flex System x240 M5 Compute Node is a high-availability, scalable compute node that is optimized to
support the next-generation microprocessor technology. It is ideally suited for medium and large businesses.
This section describes the key features of the server.
Scalability and performance
The x240 M5 offers the following features to boost performance, improve scalability, and reduce costs:
Improves productivity by offering superior system performance with up to 22-core processors, up to 55
MB of L3 cache, and up to 9.6 GT/s QPI interconnect links.
Supports up to two processors, 44 cores, and 88 threads, which maximizes the concurrent execution of
multi-threaded applications.
Intelligent and adaptive system performance with energy-efficient Intel Turbo Boost Technology 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 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 2.0 (AVX 2.0) enable acceleration of enterprise-class workloads, such
as databases and enterprise resource planning.
Up to 2400 MHz memory speeds with two DIMMs per channel (2DPC) that are running at 2400 MHz to
help maximize system performance.
Up to 1.5 TB of memory capacity using 64 GB LRDIMMs.
Optional support for high-performance PCIe-attached NVMe Flash Storage solid-state drives (SSDs) can
significantly improve I/O performance.
Supports the Storage Expansion Node, which provides another 12 hot-swap, 2.5-inch drive bays for local
storage.
Up to 32 virtual I/O ports per compute node with available 10 Gb Virtual Fabric Adapters, which offers
the choice of Ethernet, iSCSI, or Fibre Channel over Ethernet (FCoE) connectivity.
The x240 M5 offers PCI Express 3.0 I/O expansion capabilities that improve the theoretical maximum
bandwidth by 60% (8 GT/s per link), compared with 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 helps to dramatically reduce I/O latency and increase overall system
performance.
Support for high-bandwidth I/O adapters; up to two in each x240 M5 Compute Node.
Support for 40 Gb Ethernet, 16 Gb Fibre Channel, and FDR InfiniBand.
Supports the PCIe Expansion Node for support for up to six more I/O adapters.
High-speed USB 3.0 port for connectivity to external devices.
Availability and serviceability
The x240 M5 provides the following features to simplify serviceability and increase system up-time:
Chipkill, memory mirroring, and memory rank sparing for redundancy if there is a non-correctable
memory failure.
Toolless cover removal provides easy access to upgrades and serviceable parts, such as CPU, memory,
and adapter cards.
Hot-swap drives support integrated RAID-1 redundancy for data protection and greater system up-time.
A light path diagnostics panel and individual light path LEDs to quickly lead the technician to failed (or
failing) components. This feature simplifies servicing, speeds up problem resolution, and helps improve
system availability.
