What the Dell R840 Is Best At
The R840 targets SAP HANA-class in-memory databases, large OLAP/analytics platforms, dense virtualization for license-per-host savings, and any workload that scales with sockets and memory channels. Four CPUs and 6 TB of RAM in 2U remains a remarkable consolidation ratio on the refurbished market.

Frequently Asked Questions
Why choose a 4-socket R840 over two 2-socket servers?
One R840 concentrates 112 cores, 48 memory channels, and up to 6 TB RAM behind a single hypervisor or database instance — critical for workloads that cannot shard across hosts, and often cheaper on per-host software licensing than two separate machines.
How much memory can the Dell R840 hold?
48 DDR4 DIMM slots across four CPUs support up to 6 TB with 128 GB LRDIMMs. All four sockets must be populated to address all 48 slots; we’ll configure a balanced population for your target capacity.
How is a refurbished Dell R840 covered if something fails?
All Dell R840 builds include PCSP’s free 1-year warranty — covered failures are repaired or replaced with parts, labor, and shipping included. You can extend coverage to up to 5 years at checkout, and on-site service plans are offered for production deployments.
