About the Dell Precision Rack 7820
With dual LGA 3647 sockets supporting Intel Xeon Scalable processors (1st and 2nd Generation) and up to 3TB of maximum memory capacity, the Dell Precision Rack 7820 (part number 7820-BASE) delivers enterprise-grade compute density for demanding workloads. This 2U rack-mount workstation combines dual-socket architecture with exceptional memory scalability, making it the preferred choice for storage architects, AI infrastructure teams, and high-performance computing environments that demand both raw processing power and massive data handling capability.
The Dell Precision Rack 7820 is engineered for mission-critical applications requiring redundancy and reliability. Each processor socket can handle up to 205W thermal design power, while 24 DIMM slots accommodate DDR4 ECC Registered memory at speeds up to 2933MHz. The system supports multiple storage configurations—up to 12 x 3.5-inch or 16 x 2.5-inch hot-plug drive bays—with SAS, SATA, and NVMe PCIe SSD interfaces, plus PERC hardware RAID options. Six PCIe expansion slots enable flexible add-in card deployment, including optional 10GbE and InfiniBand networking alongside the dual embedded Intel Gigabit Ethernet ports. Dual redundant hot-plug power supplies (495W, 750W, 1100W, or 2000W configurations) and hot-plug fan modules ensure continuous uptime, while iDRAC9 with Lifecycle Controller provides comprehensive remote management. The system supports Windows 10 Pro for Workstations, Windows Server, Red Hat Enterprise Linux, and Ubuntu, offering flexibility across deployment scenarios.
