Key features
The Flex System x240 Compute Node is a high-availability, scalable compute node optimized to support
the next-generation microprocessor technology and is ideally suited for medium and large businesses.
This section describes the key features of the server.
Scalability and performance
The x240 offers numerous features to boost performance, improve scalability, and reduce costs:
Improves productivity by offering superior system performance with 12-core processors (up to 2.7
GHz core speeds), 10-core processors (up to 3.0 GHz core speeds), 8-core processors (up to 3.3
GHz core speeds), 6-core and 4-core processors (up to 3.5 GHz core speeds), up to 30 MB of L3
cache, and up to two 8 GT/s QPI interconnect links.
Supports up to two processors, 24 cores, and 48 threads to maximize the concurrent execution of
multithreaded applications.
Supports up to 1866 MHz memory speeds.
Up to 24 DIMM sockets for maximum scalability and performance.
Supports up to 768 GB memory with 24x 32 GB LRDIMMs.
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 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 utilize the hardware for virtualization workloads.
Intel Advanced Vector Extensions (AVX) significantly improve floating point performance for
compute-intensive technical and scientific applications compared with Intel Xeon 5600 series
processors.
The theoretical maximum memory bandwidth of the Intel Xeon processor E5 family is 51.6 GBps,
which is 60% more than in the previous generation of Intel Xeon processors.
The use of solid-state drives (SSDs) instead of or along with traditional spinning drives (HDDs) can
significantly improve I/O performance. An SSD can support up to 100 times more I/O operations per
second (IOPS) than a typical HDD.
Supports the Storage Expansion Node providing an additional 12 hot-swap 2.5-inch drive bays for
local storage.
Up to 32 virtual I/O ports per compute node with integrated 10 Gb Ethernet ports, offering the choice
of Ethernet, iSCSI, or Fibre Channel over Ethernet (FCoE) connectivity.
The x240 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 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 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 additional I/O adapters.
