Lenovo System x3750 M4


Ultra-dense design

With a dense 2U design, the Lenovo® System x3750 M4 provides advanced features and capabilities. These include support for up to four sockets and 48 DIMMs, mix and match internal storage, up to 16 HDDs or 32 1.8-inch solid state drives (SSDs), six hot-swap, dual-rotor fans and two power supplies. A Mezzanine LOM socket provides a choice of 1 Gigabit Ethernet (GbE) or 10 GbE networking options. Predictive Failure Analysis and light path diagnostics proactively monitor the system’s sub-components and provide advanced warning on power supplies, fans, VRMs, disks, processors and memory.

Pay as you grow

The x3750 M4 blends outstanding flexibility and expandability. The unique 2+2 socket design enables pay-as-you-grow processing and memory expansion to help lower cost and manage growth. The 5+3 PCIe socket design allows you to pay for I/O capabilities as needed. The x3750 M4’s capabilities and performance enable clients to reduce total cost of ownership (TCO) by consolidating multiple 2-socket servers into fewer 4-socket x3750 M4 servers.
