Hardware options installation

This chapter provides detailed instructions on how to install hardware options.

For more information on supported options, see the product QuickSpecs on the website at:

PCIe riser boards

The HPE ProLiant 920t server blade supports:

  • 2x8 full-height, full length + x16 half-height, half-length PCIe riser boards
    NOTE: All three PCIe riser slots are physically x16. The full-height, full-length slots are electrically x8. The half-height, half-length slot is electrically x16.

Memory options

IMPORTANT: This server does not support mixing LRDIMMs and RDIMMs. Attempting to mix any combination of these DIMMs can cause the server to halt during BIOS initialization. All memory installed in the server must be of the same type.

DIMM-processor compatibility

The installed processor determines the type of DIMM that is supported in the server blade. Intel Xeon processors support DDR4-3200 DIMMs. Mixing DIMM types is not supported. Install only the supported DDR4-2933 or DDR4-3200 DIMMs in the server blade.

DIMM type

The supported processor is optimized for:

  • Dual-rank and quad-rank PC4-3200 (DDR4-3200) RDIMMs or LRDIMMs operating at up to 3200 MT/s

Memory subsystem architecture

The memory subsystem in this server is divided into channels. The processor supports six channels, and each channel supports two DIMM slots.

For the location of the slot numbers, see DIMM slot locations.

This multichannel architecture provides enhanced performance in Advanced ECC mode. This architecture also enables Online Spare Memory mode.

DIMM slots in this server are identified by number and by letter. Letters identify the population order. Slot numbers indicate the DIMM slot ID for spare replacement.

General DIMM slot population guidelines

Observe the following guidelines for DIMM population:

  • White DIMM slots denote the first slot of a channel.
  • Do not mix RDIMMs and LRDIMMs.
  • When dual-rank, and quad-rank DIMMs are populated for two DIMMs per channel or three DIMMs per channel, always populate the higher number rank DIMM first (starting from the farthest slot). For example, first quad-rank DIMM and then dual-rank DIMM.
  • DIMMs must be populated starting farthest from the processor on each channel.
  • For DIMM spare replacement, install the DIMMs per slot number as instructed by the system software.

NVMe M.2 enablement option

The server blade supports installation of NVMe enablement board. Four NVMe SSDs of size 22x80mm or 22x110mm can be installed on the NVMe M.2 enablement board.

M.2 SSD option

The server blade system board supports NVMe or SATA M.2 SSDs of size 22x80mm and 22x110mm.

Installing the NVMe M.2 SSD

Prerequisites

Before you perform this procedure, make sure that you have the following items available:

  • T-10 Torx screwdriver

  • Philips No.1 screwdriver

  • NVMe M.2 SSD modules

Procedure
  1. Power down the server blade.
  2. Remove the server blade from the chassis.
  3. Remove the top cover.
  4. Do one of the following:
  5. Install the NVMe M.2 SSD module:
    1. Insert the SSD module into the SSD slot at a 45° angle.
    2. Carefully press the SSD down to the horizontal position.
    3. Install the M.2 SSD mounting screw.

      Installing the NVMe M.2 SSD
    4. If you are installing a second SSD, repeat steps a–c.
  6. Install the top cover.
  7. Install the server blade in the chassis.
  8. Power up the server blade.
