FlexMem Bridge

The PowerEdge M910 also introduces a new, Dell patent-pending technology that allows flexibility

in processor and memory scalability — FlexMem Bridge. The FlexMem Bridge allows the full amount

of addressable DIMMs on four-socket systems with Intel Xeon processor E7-2800, E7-4800 and

E7-8800 product families and Intel Xeon processor 7500 and 6500 series to be accessed, even

when only two of the processors are in place, in a completely passive solution (no active

components).

I/O 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.

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 callable memory buffers (SMBs), each of which

has two DDR3 memory channels. Each channel supports up to two RDIMMs for single-, dual- and

quad-rank. By limiting the M910 to two DIMMs per DDR channel, the system can support quad-rank

DIMMs at 1067MT/s.

PCIe 2.0

PCIe is a serial point‐to‐point interconnect for I/O devices. PCIe 2.0 doubles the signaling bit rate of

each lane from 2.5Gbps to 5Gbps. Each of the PCIe 2.0 ports is backwards‐compatible with 1.0

transfer rates.

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.

iDRAC6 Express

The iDRAC6 Express feature set is a managed persistent storage space for server provisioning data.

It consists of 1GB 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 the

system.
