This D1G model has an extensive configuration, see the specifications and the product guide. Innovative ultra-dense design Within a dense 2U design, the IBM 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 eXFlash SSD drives, six hot-swap dual rotor fans, two power supplies and integrated 1 Gigabit Ethernet (GbE) and 10 GbE networking with options for fiber or copper. - Incorporates outstanding features and capabilities in an ultra-dense design. - Offers advanced flexibility and expandability to meet changing business requirements. - Balances processing power, memory and I/O bandwidth to optimize productivity and performance. 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 allow clients to reduce total cost of ownership (TCO) by up to 52 percent over four years by consolidating multiple 2-socket servers into fewer 4- socket x3750 M4 servers. - Ultra-dense 2U, 4-socket server form factor optimized for performance and price. - Pay-as-you-grow processing and flexible options for networking, storage and performance. - Extensive I/O bandwidth for greater performance and productivity. - Scalable memory more appropriate for compute-intensive applications and virtualized environments. - 10 GbE networking with fiber or copper network options to support switching requirements. - Choice of eight different Intel Xeon E5-4600 processors to help meet your workload needs. - 2U rack. - Up to four 8-core Intel Xeon E5-4600 series processors. - Up to 48 DIMM slots with processor and memory expansion. - Five x8 low-profile PCIe Gen3 slots with optional three x16 (mechanical) x8 (electrical) full-height/half-length PCIe Gen3 slots on an expansion riser. - Up to 16 TB (2.5" HDD) or up to 6.4 TB thirty-two 1.8” eXFlash SSDs. - Two ports of 1 GbE (std.) and 10 GbE embedded controller. - 900 W or 1400 W (one standard, two maximum).
