The Dell R860 supports 4 Processors on a 2U system by stacking the processors on top of each other. There is a PEM board that gets mounted on top of the 1st and second CPU. This second board holds 2 Processors and 32 DIMMs. This design is highly efficient and will bring a lot of advantages to your configuration needs.
Accelerate a wide range of applications with this four-socket 2U air-cooled design. Deliver faster results from your core operations while consolidating into fewer, more powerful servers thanks to the latest 4th generation Intel Xeon scalable processors.
The R860 with a 2U air-cooled form factor and four (4) Intel Xeon® Scalable Processors enables businesses to accelerate a wide variety of core and business-critical applications including databases, analytics, and other data-driven applications.
The Dell OpenManage™ systems management portfolio delivers a secure, efficient, and comprehensive solution for PowerEdge servers. Simplify, automate and centralize one-to-many management with the OpenManage Enterprise console and iDRAC.
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
There is no 16 Drive Backplane. The 16x 2.5" consists of (2) 8x 2.5" SAS/SATA backplanes or (2) of the 8x 2.5" NVMe backplanes. These can be mixed in a single configuration with two PERCs installed to control each set of drives.
The R860 has only a few backplanes that can create all the configurations below.
The Dell PowerEdge R860 has a 2 or 4 socket configuration. When you install the PEM you gain access to all 64 DIMMs. Without the PEM installed, you can access 32 DIMMs on 2 sockets. Please read the manual for all the memory guidelines and limitations.

The PowerEdge R860 system supports up to two 10/100/1000 Mbps Network Interface Controller (NIC) ports embedded onthe LAN on Motherboard (LOM) and integrated on the optional Open Compute Project (OCP) cards.
NOTE: The system allows either LOM card or an OCP card or both to be installed in the system.
| Feature | Specifications |
|---|---|
| LOM card (optional) | 1 GbE x 2 |
| OCP card (OCP 3.0) (optional) | 1 GbE x 4, 10 GbE x 2, 10 GbE x 4, 25 GbE x 2, 25 GbE x 4, 100 GbE x 2 |

NOTE: APERC module must be installed in slot 3 of riser 2.
The Dell 860 Rack server can support Dual Controllers on certain configurations. One Front PERC along with One Adapter PERC or Two Front PERCs like on the 16x 2.5" NVMe RAID Option.
