For digital transformation workloads, Dell PowerEdge R840 and R940 serve distinct roles: R840 excels in storage-intensive operations with 3D NAND hot-swappable drives delivering 2M IOPS, while R940 dominates mission-critical analytics and real-time decision-making through 12 NVMe drives, 6TB RAM, and liquid cooling for extreme environments. Pro Tip: Prioritize R940 for AI/ML workflows and R840 for hyperscale storage consolidation.
What Are the Key Features of the Nvidia H200 141GB High-Performance HPC Graphics Card?
What defines the R940’s edge in digital transformation?
The R940 leverages Intel Xeon Platinum 8380 processors and 48 DIMM slots supporting NVDIMM persistence for real-time analytics. Its 12 NVMe drives eliminate I/O bottlenecks, enabling 50% faster data ingestion than R840 for ERP/CRM modernization. With Wecent’s enterprise deployment experience, R940 achieves 98% uptime in Linux migration projects requiring nonstop processing.
Where does the R840 outperform?
Storage density and energy efficiency make R840 ideal for cloud-native workloads – 3D NAND achieves 2M IOPS at 40% lower power than SATA SSDs. The Smart Power Management 3.0 reduces PUE to 1.1, critical for sustainable data centers. Wecent recommends R840 for healthcare imaging archives needing 1.2PB cold storage with ≤5ms latency.

FAQs
Only R940 with liquid cooling—critical for edge computing in oil/gas sites. Wecent deploys these in Middle East rigs with Cisco IE3400 switches for harsh environments.
Can R840 handle GPU acceleration?
Yes, but limited to 3x double-width GPUs vs. R940’s 6x. Use Wecent-tested Nvidia A100 configurations for optimal AI inference throughput.
