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 18-core processors, up to
45 MB of L3 cache, and up to 9.6 GT/s QPI interconnect links.
Supports up to two processors, 36 cores, and 72 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 2133 MHz memory speeds with two DIMMs per channel that are running at 2133 MHz to help
maximize system performance.
Up to 1.5 TB of memory capacity with 64 GB load-reduced DIMMs (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 10 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.
