Experience ultimate flexibility with Dell’s shortest depth edge server
The new Dell PowerEdge XR4000 is a 2U server with an innovative sled-based design. Dell’s shortest depth server to date is purpose-built for the edge; delivering high-performance compute and ultimate deployment flexibility in two new chassis form factors.Process and analyze data at the point of capture. Designed for workloads at the Edge including virtual desktop integration (VDI), Machine vision, Video surveillance, vSAN/VM, Point-of-sale and Data compression.

The PowerEdge XR4000, powered by Intel® Xeon® D processors, enables scalability and flexibility with a sled-based architecture and multiple mounting options.

This Server Series has 2 Chassis options, 2 Node options, and a special Witness Sled that can be installed in any configuration.
XR4000 Chassis
XR4000r
Installation Manual
The XR4000r is the "rackable" version of the XR4000 chassis options. The chassis itself has no compute capacity; it consists of a power module assembly which consists of PDB, PIB, a chassis manager, and a witness fan module. The chassis supports two AC or DC power supplies within both normal airflow (NAF) and reverse airflow (RAF). XR4000r can support four 1U sleds, two 2U sleds, or two 1U sleds plus one 2U sled. All these configurations can be matched with one optional witness sled. The witness sled slides in next to the Power Supply Units.

XR4000z
Installation Manual
The XR4000z is the "stackable" version of the XR4000 chassis options. The XR4000z is smaller in width than the XR4000r; and intended to be mounted on walls and ceilings, or stacked on each other on the shelf or under a desk. The XR4000z has no compute capacity; it consists of a power module assembly that holds a PDB, PIB, chassis manager, and a witness fan module. XR4000z supports both AC or DC power supplies with Reverse airflow (RAF) only. It supports two 1U sleds or one 2U sled. Both configurations can be matched with one optional witness sled.

XR4510C 1U Sled HighlightsBuilt for unpredictable, rugged deployments, the dense 1U, PowerEdge XR4510c enables scalability at the edge. The short depth server can fit in the rackable or stackable chassis and save much needed floor space.
XR4520C 2U Sled HighlightsBuilt for the edge, the 2U high-density PowerEdge XR4520c supports GPUs, NIC and extra storage capacity. Designed for deployment flexibility, it can fit in the rackable or stackable chassis and save much needed floor space.
XR4000w Witness Sled HighlightsThe optional Nano Server functions as an in-chassis witness node for a native, 2-node vSAN. The witness node fits even the 14" x 12" stackable server chassis and allows for virtual machine deployments where the option was previously out of the question.
The airflow direction will be chosen when selecting the chassis. All Nodes/Sleds will come automatically with that flow direction.
The XR4510c is a 1U server with only 1 row of Fans.
XR4000r: Normal airflow (NAF) and Reverse airflow (RAF)
XR4000z: Reverse airflow (RAF) only.

4 x DDR4 RDIMM or LRDIMM slots, 288-pin Up to 3200 MT/s
| Feature | XR4000 (DDR4) |
|---|---|
| DIMM Type | RDIMM and LRDIMM |
| Transfer Speed | 3200 MT/s |
| Voltage | 1.2V (DDR4) |

Only the 2U XR4520c can support an extra NIC on the Riser Kit R1C.

4x M.2 NVMe SSDs (M.2 2280 and M.2 22110) on M.2 riser module

The system supports up to 2 PSUs per server (not node/sled). You will choose the Airflow for the sleds at the top of the CTO. All other components will come with the correct airflow desired for the configuration.
XR4000r: Normal airflow (NAF) and Reverse airflow (RAF).
XR4000z: Reverse airflow (RAF) only.
RAF design is also called Reverse Airflow (RAF). RAF pulls air into the I/O side and exhausts to the side of the chassis without I/O. This allows for cold-aisle serviceability.
NAF design is also called Normal Airflow (NAF.) NAF pulls air into the non-I/O side and exhausts to the side of the chassis with I/O. This is the 'standard' way most data center servers are configured for hot-aisle serviceability.
