Dell 8 Memory 8.1 Overview The PowerEdge R910 uses DDR3 memory providing a high-performance, high-speed memory interface capable of low latency response and high throughput. The R910 supports Registered ECC DDR3 DIMMs (RDIMM). R910 uses Intel 7500 series CPUs that have two integrated memory controllers. Each of those memory controllers then has two Scalable Memory Interconnect (SMI) channels that connect to the memory buffer.
PAGE 38
Dell Figure 18.
PAGE 39
Dell 8.2 Slots/Risers R910 has 8 memory risers; each memory riser has 8 DIMM slots. So there are a total of 64 DIMMs. See System Memory in the Hardware Owner’s Manual for detailed information. 8.
PAGE 40
Dell 8.6 Mirroring For mirroring, the PowerEdge R910 supports 2P/4P configurations for 64GB and larger only. When mirroring is enabled, only half of the physical memory is visible to the system software. A full copy of the memory is maintained, and in the event of an uncorrectable error, the system will switch over to the mirrored copy. The R910 uses intra-socket mirroring. 8.7 RAID The PowerEdge R910 does not support memory RAID. 8.
PAGE 41
Dell 9 Chipset The R910 system-board incorporates the Intel 7500 chipset (Boxboro‐EX) for I/O and processor interfacing. The Intel 7500 chipset is designed to support Intel’s 6500 and 7500 4S processor family, QPI interconnect, DDR3 memory technology, and PCI Express Generation 2. The Intel 7500 chipset consists of the EX IOH, Intel® 7500 Scalable Memory Buffer, and the ICH10 South Bridge. 9.

Dell 13.6 Storage Controllers 13.6.1 PERC H200 The PERC H200 integrated HBA is a SAS 2.0 6Gb native PCIe half-length half-height expansion card that plugs into a dedicated x8 storage slot. It supports RAID0, RAID1, RAID10 and non-RAID HDD configurations. It incorporates one four-channel mini-SAS internal connector (SFF8087) for connection to internal x4 2.5‖ drive backplane. Since there are a maximum of up to 4-drives, the second mini-SAS connector from H200 to the backplane would not get used.

Dell 13.7 LED Indicators Each hard drive carrier has two LED indicators visible from the front of the system. One is a green LED for disk activity and the other is a bicolor (Green/Amber) LED for status information. The activity LED is driven by the disk drive during normal operation. The bicolor LED is controlled by the SEP device on the backplane. Both LEDs are used to indicate certain conditions under direction of a storage controller.

Dell 14 Video The R910 Integrated Dell Remote Access Controller 6 (iDRAC6) incorporates an integrated video subsystem, connected to the 32-bit PCI interface of the ICH10. This logic is based on the Matrox G200. The device only supports 2D graphics. The video device outputs are multiplexed between the front and rear video ports. If a monitor is connected to the front video connector, it will take precedence over the rear connection, thereby removing the display from the rear connection.

Dell 16 Rack Information 16.1 Overview The ReadyRails™ sliding rail system for the R910 provides tool-less support for racks with square or unthreaded round mounting holes including all generations of Dell racks. The optional cable management arm (CMA) can be mounted on either the left or right side of the sliding rails without the use of tools for fast and easy deployment.
PAGE 58
Dell *Adapter brackets are available from RackSolutions that allow the R910 sliding rails to mount in threaded racks. The only option available for 2-post racks is to mount the system on a fixed shelf. Other factors to consider when deploying the R910 include the spacing between the front and rear mounting flanges of the rack, the type and location of any equipment mounted in the back of the rack such as power distribution units (PDUs), and the overall depth of the rack.
PAGE 59
Dell Figure 24. R910 Mounted in the B2 Sliding Rails The R910 CMA can be mounted to either side of the rails without the use of tools or the need for conversion, but it is recommended that it be mounted on the side opposite the power supplies to allow easier access to the power supplies for service or replacement.
