Cyber Resilient Architecture for Zero Trust IT environment & operations

Security is integrated into every phase of the PowerEdge lifecycle, including protected supply chain and factory-to-site integrity assurance. Silicon-based root of trust anchors end-to-end boot resilience while Multi-Factor Authentication (MFA) and role-based access controls ensure trusted operations.

Cooling & Fans

With most GPU servers the cooling is a major part of the success of the machine running smoothly and efficiently. The XE8640 Rack Server holds up to 6 Standard (STD) fans installed in the mid tray and up to 5 High performance (HPR) gold grade fans installed on the front of the system. A keynote is that all the fans are hot-swappable and when GPUs are installed you can install the Liquid Assisted Air Cooling for GPU.

Note: No facility water to rack required.

RDIMM 3DS	4R X 4	128GB	4800 MT/s	4400 MT/s

GPU

This is a GPU-intense server for HPC, AI, and Machine Learning systems. The Dell XE8640 Rack Server supports 4x NVIDIA SMX5 GPUs w/ NVLINK HGX H100 80 GB/700 W. The system board connects to these GPUs via the Versabay Board (VSB). The Versabay Boards are designed to offer flexibility in terms of adding extra functionalities such as additional storage controllers, network interface cards (NICs), or specialized processing units.

The Dell PowerEdge XE8640 supports the LAAC liquid Cooling option to help with the system temperature. View the manual for more details into the GPU and cooling.

Expansion Slots

The XE8640 GPU server only has two riser cards and 1 riser configuration. You simply have the choice of whether to install risers or not. Each Riser comes with 2 PCIe 5 x16 ports with slots available for FH HL riser cards.

PCIe Riser Configurations 1. R1A+R4A

Location	Height	Length	CPU1	CPU2
Location	Height	Length	Riser R1A	Riser R4A
PCIe Slot -1	FH	HL	PCIe Gen5 X16	N/A

PCIe Slot -3	FH	HL	N/A	PCIe Gen5 X16
PCIe Slot -4	FH	HL	N/A	PCIe Gen5 X16

Networking

The LOM and the OCP 3.0 x8 are great ways to expand the networking ability of the XE8640 without losing one of the 4 PCIe 5.0 slots available. The OCP can handle a combined speed of 100GbE across 4 ports.

Feature	Specifications
LOM card	1 GbE x 2
OCP card (OCP 3.0)	10 GbE x 4, 25 GbE x 2, 25 GbE x 4

Storage Controllers

The XE8640 Rack server supports the PERC 12 H965i for Hardware RAID along with the S160 for Software RAID. In addition, the rack server also holds the BOSS-N1 Modular Internal Boot device. This BOSS-N1 holds two M.2 NVMe SSD drives with a capacity of 480GB or 960GB.

Supported storage controller card

Power & Dimensions

The PowerEdge XE8640 system supports up to 4 AC or DC power supply units (PSUs) with 3+1 redundancy, autosensing, and auto-switching capability. Similar to the Riser config there is only one choice for a Power Supply Unit. The XE8640 can support up to 4x 2800W 200-240V PSUs. This type of battery is needed when installing a SMX5 GPU which consumes 700W during peak performance.
