Frequently Asked Questions — Dell PowerEdge R440
The Dell PowerEdge R440 supports up to 1 TB of DDR4 LRDIMM RAM across 16 DIMM slots (8 GB, 16 GB, 32 GB, or 64 GB modules per slot at up to 2666 MT/s). RDIMM configurations cap at 512 GB, which Dell recommends for performance-optimized workloads. Only RDIMMs and LRDIMMs are supported — UDIMMs are not compatible with the Intel Xeon Scalable platform. The dual-socket architecture with 6 memory channels per CPU delivers significantly higher aggregate bandwidth than single-socket entry servers. Configure your R440 memory at ECS.
The Dell PowerEdge R440 holds up to ten 2.5-inch hot-plug drives (SAS, SATA, or NVMe PCIe SSD) in the maximum-density 10-bay chassis, with up to 4 of those bays configured as NVMe SSDs for up to 76.8 TB raw capacity. The 8-bay chassis holds 8 × 2.5-inch SAS/SATA drives, and the 4-bay chassis supports 4 × 3.5-inch SAS/SATA drives (up to 64 TB). The BOSS M.2 boot module keeps all data bays free by providing a dedicated OS boot drive separate from the front bays.
Yes. The Dell PowerEdge R440 supports up to 4 NVMe PCIe SSDs in the 10-bay 2.5-inch chassis configuration via CPU-direct-attach PCIe lanes — bypassing the RAID controller and PCH for maximum throughput and minimum latency.
