Dual Xeon Gold 6246 Rack Server
The Dell PowerEdge R640 is a 1U rack server built around two Intel Xeon Gold 6246 processors. Each CPU provides 12 cores at 3.30 GHz, giving 24 cores and 48 threads total. With 256 GB of DDR4 memory installed across 24 DIMM slots and a maximum capacity of 3 TB, it targets virtualization hosts, database nodes, and AI inference workloads that demand high core counts and large memory footprints. Windows Server 2025 comes pre-installed for immediate deployment.
Verify Power and Rack Requirements
Confirm your facility can supply redundant power to the server and that your rack provides standard 1U mounting space with adequate airflow for the redundant fan assembly. The system uses an LGA 3647 socket platform limited to two processors, so no further CPU expansion is possible. Two PCIe 3.0 slots are available for additional controllers or network adapters. Ensure your management network can reach the iDRAC9 interface for remote monitoring and firmware updates.
Air-Cooled Chassis with Front and Rear VGA
The rack-mount kit secures the unit in a standard enclosure while the redundant fans maintain thermal stability under sustained load. Two 4 TB NVMe SSDs are configured in RAID 1 via the H730P controller, delivering 4 TB of usable capacity with mirroring for data protection. Connectivity includes one USB 2.0 port, two USB 3.0 ports, and VGA outputs on both the front and rear panels for local console access. TPM 2.0 and Secure Boot are enabled to support platform integrity requirements.

Questions about this item
What components are included in the box and what must be purchased separately?
The box contains the Dell PowerEdge R640 server, power cables, a rack mount kit, Windows Server 2025 pre-installed, and a user manual. Additional DDR4 memory modules or PCIe 3.0 expansion cards are not included.
Which memory capacity should I choose given the 256GB installed and 3TB maximum?
The system ships with 256GB DDR4 across 24 DIMM slots and supports up to 3TB total. Choose 256GB for standard virtualization; add more modules only if workloads require larger in-memory datasets.
How does the 8TB NVMe RAID 1 configuration perform for database workloads?
Two 4TB NVMe drives in RAID 1 provide 4TB usable capacity with mirrored redundancy. Read performance benefits from both drives; write latency matches a single drive, protecting data without sacrificing speed.
