x3750 M4
Exceptional flexibility and performance in a dense 2U, 4-socket 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.

x3850 X6
Innovation for business advantage
While the volume of data and transactions continues to grow exponentially, businesses remain constrained by a finite set of capital and operational resources. The two must be reconciled. With the System x3850 X6 four-socket rack server featuring enterprise X ARCHITECTURE® innovations and Intel® Xeon® Processor E7 v2 families, applications can perform up to 125 percent faster1. And by replacing external SAN/NAS storage units with high-capacity internal eXFlash memory-channel storage, you can also reduce infrastructure costs and complexity.

x3950 X6
If your business demands the highest performance in an x86 system, the System x3950 X6 eight-socket server is designed to easily scale performance and manage large amounts of data reliably. Featuring enterprise X ARCHITECTURE® innovations and Intel® Xeon® Processor E7 v2 families, applications can perform 125 percent faster1. And by replacing external SAN/NAS storage units with high-capacity internal eXFlash memory-channel storage, you can also reduce infrastructure costs and complexity.
