Experience ultimate flexibility with Dell’s shortest depth edge server
Dell Technology’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.
- Expand as needed with options for 1U or 2U compute sleds and up to 4 servers in single 2U chassis
- Flexible mounting options: rack or wall-mountable chassis
- Operate in environments outside of traditional data centers with -5 to 55c operating temperatures
- Ideal for analytics, AI inferencing, IoT, vSAN, MEC, point of sale
- Can operate in temp ranges from -5C to 55C and is rated to MIL 810H and NEBS Level 3
- Gain ultimate deployment flexibility with optional ‘stackable’ and ‘rackable’ chassis with options to mount on walls or place on shelves when space is at a premium
- Withstand dusty and harsh environments while providing extra physical security with an optional lockable intelligent filtered bezel

- Create a self-contained 2-node VM cluster in a footprint not much larger than a shoebox with dell Nano Witness Server included in-chassis
- Rackable chassis supports up to 4 separate server nodes in a single 2U chassis
- Storage up to 12 x M.2 NVMe for total capacity of 45Tb per sled
- Uses Intel® Xeon D® with up to 20 cores per node for ultimate edge performance
- Reduce service complexity with a sled-based chassis that allows for a ‘pull replace-repair’ model
- Scale when you need it by adding sleds as your operation demands grow.
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 Chassis
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.
- Up to 4 x M.2 NVMe drives, from 480GB up to 3.84TB/ea
- Up to 2 x M.2 NVMe BOSS N1 ET
- 4 x memory slots; up to 512GB total
- 4 x SFP from CPU
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.
- Up to 4 x M.2 NVMe drives, from 480GB up to 3.84TB/ea
- Up to 2 x M.2 NVMe BOSS N1 ET
- 4 x memory slots; up to 512GB total
- 4 x SFP from CPU

- Optional 4 x M.2 NVMe storage Adapter (can support 2 adapters on riser 1C); 12 x M.2 NVMe total = 1 Riser card + 2 PCIe Riser AIC.
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.
- Intel® Atom® C3508 CPU
- 16GB ECC memory
- 2 x i210 NIC
- M.2 NVMe drive for OS and storage
- Micro Controller Unit (MCU) for management
- Secure boot
The airflow direction will be chosen when selecting the chassis. All Nodes/Sleds will come automatically with that flow direction.
XR4000r: Normal airflow (NAF) and Reverse airflow (RAF)
XR4000z: Reverse airflow (RAF) only.

The XR4520c Sled is the only sled that can install the Riser Kit (R1C). That makes the XR4520c the only system to support up to two 150W single-width GPUs or one 250W double-width GPU.
The XR4520c also supports the installation of Two 4x M.2 NVMe SSDs AIC.
It's also the only server to expand the networking capabilities if you desire to install another NIC.
Read below for more details.

- 10GbE x 4 (max 50Gb)
For processors with up to 8 cores. - 25GbE x 4 (max 100Gb)
For processors with 12-20 cores or more.
Only the 2U XR4520c can support an extra NIC on the Riser Kit R1C.
Dell Poweredge XR4000w Witness Sled
2x 1 GbE (intel I210) LOM

XR4510c & XR4520c:
4x M.2 NVMe SSDs (M.2 2280 and M.2 22110) on M.2 riser module
XR4520c Only:
When Riser 1C is installed you have two extra PCIe slots. Each slot can hold another 4x M.2 NVMe SSDs AIC. For a total of 8 extra M.2 NVMe SSDs.
XR4000w Only:
1 x M.2 SSD of 960 GB (2280) NVMe SSD 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.
