DellPowerEdge M910 Technical Guide 11 Streaming SIMD (Single Instruction, Multiple Data) Extension 4 Intel® 64 Technology Intel® VT-x and VT-d Technology for virtualization support Enhanced Intel® SpeedStep® Technology Demand-based switching for active processor power management as well as support for ACPIP-States, C-States, and T-States2.2.3 FlexMem BridgeThe PowerEdge M910 also introduces a new, Dell patent-pending technology that allows flexibility inprocessor and memory scalability—FlexMem Bridge. The FlexMem Bridge allows the full amount ofaddressable DIMMs on 4-Socket systems with Intel Xeon E7-2800, E7-4800 and E7-8800 product family andIntel Xeon processor 7500 and 6500 series to be accessed, even when only 2 of the processors are inplace, in a completely passive solution (no active components).2.2.4 IO Hub (IOH) with Intel QuickPath ArchitectureThe Intel QuickPath Architecture consists of serial point-to-point interconnects for the processorsand the system IOH. The M910 has a total of eight QuickPath Interconnects (QPI) lines: six linksconnecting the processors and two links connection processors 1 and 2 with the IOH.2.2.5 DDR3 MemoryThe M910 uses DDR3 memory, which provides a high-performance, high-speed memory interfacecapable of low latency response and high throughput. The M910 supports Registered ECC DDR3 DIMMs(RDIMMs).The DDR3 memory interface consists of 8 Intel Scalable Memory Buffers (SMBs), each of which hastwo DDR3 memory channels. Each channel supports up to two RDIMMs for single/dual/quad rack. Bylimiting to two DIMMs per DDR channel, the system can support quad-rank DIMMs at 1067MT/s.2.2.6 PCI Express Generation 2PCI Express is a serial point‐to‐point interconnect for I/O devices. PCIe Gen2 doubles the signaling bitrate of each lane from 2.5 Gb/s to 5 Gb/s. Each of the PCIe Gen2 ports is backwards‐compatible withGen1 transfer rates.2.2.7 Internal Redundant SD ModuleThe Internal SD Module is dedicated for an SD Flash Card with embedded Hypervisor forvirtualization. The SD Flash Card contains a bootable OS image for virtualized platforms.The persistent storage solution on the M910 allows for redundant SD cards.2.2.8 iDRAC6 ExpressThe iDRAC6 Express feature set is a managed persistent storage space for server provisioning data. Itconsists of 1 GB flash and vFlash (an optional externally accessible SD card). vFlash offers the hot-plug portability and increased storage capacity benefits of SD while still being managed by thesystem.
