FAQs

Q: What AMD EPYC processors are supported in the R7425?
A: The PowerEdge R7425 supports first-generation AMD EPYC 7000 series processors (codenamed Naples) with up to 32 cores per processor. The system can accommodate one or two processors for a maximum of 64 cores and 128 threads in a dual-processor configuration.

Q: How much memory can the R7425 support?
A: The R7425 features 32 DDR4 DIMM slots supporting both RDIMM and LRDIMM modules with speeds of 2666 MT/s, 2400 MT/s, 2133 MT/s, and 1866 MT/s. Maximum memory capacity is 4TB with 128GB LRDIMMs installed in all slots.

Q: What storage configurations are available?
A: The R7425 offers multiple storage configurations: front bays support up to 24x 2.5-inch or 12x 3.5-inch drives (SAS, SATA, NVMe for 2.5-inch; SAS/SATA only for 3.5-inch). Optional mid-plane supports 4x 2.5-inch NVMe or 4x 3.5-inch drives, and rear bay supports 4x 2.5-inch or 2x 3.5-inch drives, enabling up to 32 total drives in maximum configuration.

Q: What RAID controllers are compatible with the R7425?
A: Internal RAID controllers include PERC H330+, H730+, and H740P, plus HBA330 for non-RAID configurations. External storage is supported via PERC H840. The server also supports software RAID via S140, and boot-optimized storage through BOSS-S1 (hardware RAID for 2x M.2 drives), Internal Dual SD Module, or Internal USB.

Q: What is the PCIe expansion capability?
A: The R7425 supports up to 8x PCIe Generation 3 expansion slots installed via expansion card risers.
