Optional Features
Server Management
HPE iLO Advanced
HPE iLO Advanced licenses offer smart remote functionality without compromise, for all HPE ProLiant servers. The license includes the full integrated remote console, virtual keyboard, video, and mouse (KVM), multi-user collaboration, console record and replay, and GUI-based and scripted virtual media and virtual folders. You can also activate the enhanced security and power management functionality.
Cooling Options
These optional cooling technologies are compatible with both air cooled and liquid cooled HPE servers.
HPE Adaptive Rack Cooling System (ARCS)
This cooling solution supports up to 4 full racks (servers, networking or storage) and manages 100% of the server heat in a completely enclosed cluster. It provides cool air for inlet side and manages exhaust heat, transferring it to facility water cooling. When servers with DLC are added to ARCS, the highest rack density is possible, with 100% heat transfer to facility water.
Learn more at http://www.hpe.com/psnow/doc/a00051240enw
HPE Rear Door Heat Exchanger (RDHX)
This cooling solution attaches to the back of a single rack (servers, networking or storage) and neutralizes the hot air existing the rack by transferring the heat to facility water cooling. When servers with DLC are added to RDHX, the highest rack density is possible, with 100% heat transfer to facility water.

Rack and Power Infrastructure
The story may end with servers, but it starts with the foundation that makes compute go – and business grow. We’ve reinvented our entire portfolio of rack and power products to make IT infrastructure more secure, more practical, and more efficient. In other words, we’ve created a stronger, smarter, and simpler infrastructure to help you get the most out of your IT equipment. As an industry leader, Hewlett Packard Enterprise is uniquely positioned to address the key concerns of power, cooling, cable management and system access.
HPE G2 Advanced and Enterprise Racks are perfect for the server room or today’s modern data center with enhanced airflow and thermal management, flexible cable management, and a 10 year Warranty to support higher density computing.
HPE G2 PDUs offer reliable power in flexible form factors that operate at temperatures up to 60°C, include color-coded outlets and load segments and a low-profile design for optimal access to the rack and support for dense rack environments.
HPE Uninterruptible Power Systems are cost-effective power protection for any type of workload. Some UPSs include options for remote management and extended runtime modules so your critical dense data center is covered in power outages.
HPE KVM Solutions include a console and switches designed to work with your server and IT equipment reliably. We’ve got a cost-effective KVM switch for your first rack and multiple connection IP switches with remote management and security capabilities to keep your data center rack up and running.

HPE Rack Information
- − S4H39A is required for 48U racks
- − S4H40A is required for 42U racks
HPE strongly recommends the use of HPE racks. If non-HPE racks are used, please be aware that cable bend radius requires the following to close the door of the rack:
- − 150 mm space in front of the rack
- − 100 mm space in the rear of the rack
- − Consideration of additional space required for PDUs and a DLC solution that will include manifolds

Notes:
− HPE ProLiant Compute XD685 only supports dual processor configurations, not single processor configurations.
− Mixing of 2 different processor models is NOT supported.
− DDR5 speed is the maximum memory speed of the processor. Actual memory speed may depend on the quantity and type of DIMMs installed.

Step 3: Choose Memory Options
Please select memory kits from below.
For memory population rule whitepaper and optimal memory performance guidelines, please go to:
Notes:
− Rank mixing is not allowed.
− No x4 mixing with x8 across a socket.
− 6400 MT/s memory SKUs offer a transfer rate of up to 6400 MT/s at 1 DIMM per channel and The maximum memory speed and capacity is a function of the memory type, memory configuration, and processor model.
− Speeds can drop to 6000/5600 in 2PDC configurations. 256 GB option is unlikely to be available or priced reasonably given industry-wide memory shortages
− HPE Server Memory compatibility for a specific server platform may vary or be limited within a server platform depending upon the specific configuration being requested. Because each server environment and requirements can vary, memory compatibility is based not only upon the server family but may also be affected by the amount and type of additional hardware options installed within a specific server configuration. For this reason, some HPE memory DIMMs may be qualified for an HPE server model or family and yet occasionally not be supported with some configurations within that server family.

Memory
Memory Population guidelines
General Memory Population Rules and Guidelines:
- − To maximize performance, it is recommended to balance the total memory capacity between all installed processors.
- − When two processors are installed, balance the DIMMs across the two processors.
- − The maximum memory speed is a function of the memory type, memory configuration, and processor model.
- − The maximum memory capacity is a function of the number of DIMM slots on the platform, the largest DIMM capacity qualified on the platform, the number and model of installed processors qualified on the platform.
- − To realize the performance memory capabilities listed in this document, HPE DDR5 Smart Memory is required. For additional information, please see the: HPE DDR5 Smart Memory QuickSpecs
- − For General Server Memory Population Rules and Guidelines and HPE Server Memory speed, see details here:
