2.2.3
FlexMem Bridge
The PowerEdge M910 also introduces a new, Dell patent-pending technology which will allow
flexibility in processor and memory scalability—FlexMem Bridge. The FlexMem Bridge allows the full
amount of addressable DIMMs on 4-Socket systems with
Intel Xeon E7-2800, E7-4800 and E7-8800 product
family and
Intel Xeon processor 7500 and 6500 series to be accessed, even when only 2 of the
processors are in place, in a completely passive solution (no active components).
2.2.4
IO Hub (IOH) with Intel QuickPath Architecture
The Intel QuickPath Architecture consists of serial point-to-point interconnects for the processors
and the system IOH. The M910 has a total of eight QuickPath Interconnects (QPI) lines: six links
connecting the processors and two links connection processors 1 and 2 with the IOH.
2.2.5
DDR3 Memory
The M910 uses DDR3 memory which provides a high-performance, high-speed memory interface
capable of low latency response and high throughput. The M910 supports Registered ECC DDR3 DIMMs
(RDIMMs).
The DDR3 memory interface consists of eight Intel Scalable Memory Buffers (SMBs), each or which has
two DDR3 memory channels. Each channel supports up to two RDIMMs for single/dual/quad rack. By
limiting to two DIMMs per DDR channel, the system can support quad-rank DIMMs at 1067MHz.
2.2.6
PCI Express Generation 2
PCI Express is a serial point
‐
to
‐
point interconnect for I/O devices. PCIe Gen2 doubles the signaling bit
rate of each lane from 2.5 Gb/s to 5 Gb/s. Each of the PCIe Gen2 ports is backwards
‐
compatible with
Gen1 transfer rates.
2.2.7
Internal Redundant SD Module
The Internal SD Module is dedicated for an SD Flash Card with embedded Hypervisor for
virtualization. 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 Express
The iDRAC6 Express feature set is a managed persistent storage space for server provisioning data. It
consists of 1 GB flash and vFlash media (an optional externally accessible SD card). vFlash media
offers the hot-plug portability and increased storage capacity benefits of SD while still being
managed by the system.
