Key features
The IBM System x3750 M4 blends outstanding flexibility and expandability. The x3750 M4 2+2 socket
design enables pay-as-you-grow processing with the new Intel Xeon E5-4600 series processors and
memory scalability to help lower cost and manage growth. The 5+3 PCIe socket design allows you to pay
for PCIe capabilities as needed.
With the capability to support up to 48 DIMMs, four sockets, mix and match internal storage with up to 16
HDDs or 32 eXFlash SSD drives, 6 hot-swap dual rotor fans, two power supplies, and integrated 10 GbE
networking with options for fiber or copper, the x3750 M4 provides unmatched features and capabilities in
a dense 2U design.
Scalability and performance
The x3750 M4 offers numerous features to boost performance, improve scalability, and reduce costs:
The Intel Xeon processor E5-4600 product family improves productivity by offering superior system
performance with 8-core processors and up to 2.9 GHz core speeds, up to 20 MB of L3 cache, and up
to two 8 GTps QPI interconnect links.
The x3750 M4 2+2 processor socket design enables pay-as-you-grow processing with the Intel new
Xeon E5-4600 series processors and memory scalability to help lower cost and manage growth.
Up to four processors, 32 cores, and 64 threads maximize the concurrent execution of multithreaded
applications.
Intelligent and adaptive system performance with Intel Turbo Boost Technology 2.0 allows processor
cores to run at maximum speeds during peak workloads by temporarily going beyond processor 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 (AVX) improve floating-point performance for compute-intensive
technical and scientific applications compared to Intel Xeon 5600 series processors.
The outstanding RDIMM memory performance of the x3750 M4 is achieved by supporting three
DIMMs per channel configurations at speeds up to 25% faster than the Intel specification.
48 Load Reduced DIMMs (LRDIMMs) of 1333 MHz DDR3 ECC memory provide speed, high
availability, and a memory capacity of up to 1.5 TB.
LR-DIMM speeds implemented in the x3750 M4 are also 25% beyond the Intel specification at 1.35 V
for one, two, and three DIMM per channel configurations. This configuration improves performance
and reduces overall system power at the same time, all while maintaining reliability
The use of IBM eXFlash solid-state drives (SSDs) instead of, or along with, traditional spinning 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 16 HDDs or 32 eXFlash SSDs, together with an optical drive at the same time, provide a
flexible and scalable all-in-one platform to meet your increasing demands.
The server offers a SAS switch backplane option (88Y7421) to allow up to 16 SFF devices to attach
to a single controller.
The server has two integrated Gigabit Ethernet ports and two optional 10 Gb Ethernet ports that do
not consume PCIe slots.
The 5+3 PCI Express socket design of the server allows you to pay for PCIe capabilities as needed.
