Dell PowerEdge R7525 with 24 NVMe drives
The Dell Poweredge R7525 24 NVMe configuration takes advantage of the above configuration. All
24 x4 NVMe drives are directly connected to the CPUs using up 96 of the available 160 lanes. This
ensures that none of the NVMe drives have any oversubscription. All NVMe drives are directly
connected maximizing throughput and reducing latency. The high core count of the 2
nd
Gen AMD
EPYC 7002 series also helps take advantage of this available lanes. The remaining 64 PCIe lanes
are split up across 2 x16 slots, 1 x16 OCP 3.0 slot and 2 x8 slots that can be used for other
peripherals like network cards.

In Conclusion
The 24 NVMe drive R7525 is a very flexible platform. It has support for high powered 2nd
Generation AMD EPYC 7002 series processors with up to 64 physical cores per processor, 24
NVMe drives directly connected to the CPUs and multiple PCIe Gen4 slots for peripheral support.
This combination provides a platform that is optimized for storage bandwidth yet does not scrimp
on additional peripheral support.
