Outstanding RAS and high-efficiency design improves yourbusiness environment and helps save operational costs.Scalability and performanceThe x3550 M4 offers numerous features to boost performance, improve scalability, and reduce costs:The Intel Xeon processor E5-2600 product family improves productivity by offering superior systemzperformance with 8-core processors and up to 2.9 GHz core speeds, up to 20 MB of L3 cache, and upto two 8 GT/s QPI interconnect links.Up to two processors, 16 cores, and 32 threads maximize the concurrent execution of multithreadedzapplications.Intelligent and adaptive system performance with Intel Turbo Boost Technology 2.0 allows CPU coreszto run at maximum speeds during peak workloads by temporarily going beyond processor TDP.Intel Hyper-Threading Technology boosts performance for multithreaded applications by enablingzsimultaneous multithreading within each processor core, up to two threads per core.Intel Virtualization Technology integrates hardware-level virtualization hooks that allow operatingzsystem vendors to better utilize the hardware for virtualization workloads.Intel Advanced Vector Extensions (AVT) significantly improve floating point performance forzcompute-intensive technical and scientific applications compared to Intel Xeon 5600 seriesprocessors.The 24 Load Reduced DIMMs (LRDIMMs) of 1333 MHz DDR3 ECC memory provide speed, highzavailability, and a memory capacity of up to 768 GB (running at 1066 MHz).The theoretical maximum memory bandwidth of the Intel Xeon processor E5 family is 51.6 GB/s,zwhich 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) canzsignificantly improve I/O performance. An SSD can support up to 100 times more I/O operations persecond (IOPS) than a typical HDD.The server has four integrated Gigabit Ethernet ports and two optional 10 Gb Ethernet ports withzmezzanine cards that do not consume a PICe slot.The server offers PCI Express 3.0 I/O expansion capabilities that improve the theoretical maximumzbandwidth by 60% (8 GT/s 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 Xeonzprocessor E5 family. This helps to dramatically reduce I/O latency and increase overall systemperformance.
