System overview
The Dell Technologies PowerFlex custom node R6525 system is a 1U rack server that supports:
●Two AMD EPYCTM 7002 or 7003 series processors
●32 DIMM slots
●Two redundant AC or DC power supply units
●Up to 8 x 2.5-inch, or 10 x 2.5-inch SAS, SATA, or NVMe drives.
NOTE: For more information about how to hot swap NVMe PCIe SSD U.2 devices, see the Dell Express Flash NVMe
PCIe SSD User's Guide at https://www.dell.com/support. Look for Data Center Infrastructure > Storage Adapters &
Controllers > Dell PowerEdge Express Flash NVMe PCIe SSD > Documentation > Manuals and Documents.
NOTE: All instances of SAS, SATA drives, PCIe SSDs, and NVMe are referred to as drives in this document, unless specified
otherwise.
WARNING: Consumer-grade GPUs should not be installed or used in Enterprise Server products.
For more information about supported drives, see the www.dell.com/poweredgemanuals section.
For more information, see the Dell Technologies PowerFlex custom node R6525 technical specifications on the product
