IBM System x3650 M4 BD Product Guide 2Key featuresBacked by IBM worldwide service and support, the x3650 M4 BD is developed, quality-tested, andcertified by IBM, the leading vendor in technology patents for 20 years running. IBM System x®advancements in scalability, reliability, and performance can help your business innovate and thrive. Withmore flexible configuration options, energy-efficient components, and robust systems management tools,the x3650 M4 BD is an innovative design by IBM that can deliver business value over the long term.Scalability and performanceThe x3650 M4 BD offers numerous features to boost performance, improve scalability, and reduce costs:The Intel Xeon processor E5-2600 v2 product family improves productivity by offering superiorsystem performance with up to 12-core processors (up to 2.4 GHz core speeds) or up to 2.8 GHz corespeeds (10-core processors), up to 30 MB of L3 cache, and QPI interconnect links of up to 8 GTps.Up to two processors, 24 cores, and 48 threads maximize the concurrent running of multithreadedapplications.Intelligent and adaptive system performance with Intel Turbo Boost Technology 2.0 allows processorcores to run at maximum speeds during peak workloads by temporarily going beyond processorthermal design power (TDP).Intel Hyper-Threading Technology boosts performance for multithreaded applications by enablingsimultaneous multithreading within each processor core, up to two threads per core.Intel Virtualization Technology integrates hardware-level virtualization hooks that allow operatingsystem vendors to better use the hardware for virtualization workloads.Intel Advanced Vector Extensions (AVT) improve floating point performance for compute-intensivetechnical and scientific applications.Support for up to 512 GB of memory through 16 DIMM slots with 32 GB LRDIMMs.Support for two DIMMs per channel running at 1866 MHz to help maximize system performance.The use of solid-state drives (SSDs) instead of, or along with, traditional spinning drives (HDDs) canimprove I/O performance. An SSD can support up to 100 times more I/O operations per second(IOPS) than a typical HDD.The server offers three integrated Gigabit Ethernet ports, one dedicated 1 GbE management port,and optional embedded 10 GbE ports for flexible network connectivity.The server offers PCI Express (PCIe) 3.0 I/O expansion capabilities that improve the theoreticalmaximum bandwidth by almost 100% (8 GTps per link using 128b/130b encoding) compared to theprevious 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 Xeonprocessor E5 family. This controller helps to reduce I/O latency and increase overall systemperformance.Up to fourteen 3.5-inch hot-swap drive bays provide maximum internal storage density of up to 56 TBin a 2U form factor.Availability and serviceabilityThe x3650 M4 BD provides many features to simplify serviceability and increase system uptime:The server offers Chipkill, memory mirroring, and memory rank sparing for redundancy in the event ofa non-correctable memory failure to prevent an unplanned outage.Tool-less cover removal provides easy access to upgrades and serviceable parts, such as processor,memory, and adapters.
