2.2.3

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 4-Socket systems with

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 8 Intel Scalable Memory Buffers (SMBs), each of 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 1067MT/s.

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 (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.
