The x3650 M4 HD offers numerous features to boost performance, improve scalability, and reduce costs:

  • Featuring the Intel Xeon processor E5-2600 v2 product family, which improves productivity by offering superior system performance with up to 12 core per processors, core speeds up to 3.5 GHz, L3 cache up to 30 MB, 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.
  • Supports up to 24 Load Reduced DIMMs (LRDIMMs) of 1866 MHz DDR3 ECC memory, which provide speed, high availability, and a memory capacity of up to 768 GB (running at 1066 MHz).
  • The use of solid-state drives (SSDs) instead of, or along 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.
  • Up to 26x 2.5-inch bays or a combination of up to 16x 2.5-inch bays and 16x 1.8-inch SSD bays provide a flexible and scalable platform to meet your increasing demands.
  • The server has four integrated Gigabit Ethernet ports and two optional 10 Gb Ethernet (or InfiniBand) ports with mezzanine cards that do not use PICe slots.
  • The server offers PCI Express 3.0 I/O expansion capabilities that improve the theoretical maximum bandwidth by 60% (8 GTps per link) compared to 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 reduce I/O latency dramatically and increase overall system performance.
  • Support for up to two NVIDIA Quadro graphics processing units (GPUs) to maximize computing power.
