Bottom line:

The Dell EMC PowerEdge R7425 is cheaper than the Dell EMC R840, has fewer processors and less memory. But the latest AMD processors give it enough oomph to make it suitable for enterprise deployments such as VDI, memory-intensive applications and scale up software-defined deployments.

The Dell PowerEdge R7425 server can manage hundreds of virtual desktop environments cost effectively. Tasks such as updating system parameters, applying security policies and performing data protection activities are centralized and performed from a single server. It also offers management, security and operational efficiencies.

If you need more than a commodity server and are willing to pay just a little more, this one should be on your short list.

Product description:

The Dell EMC PowerEdge R7425 design makes it easy to add extreme memory and storage capacity for low latency, data intensive workloads. Users can pack a whole lot of storage performance into this 2U rack server. Up to 64 cores, up to 32 memory DIMMs, and 128 lanes of PCIe offer high memory bandwidth for database applications. It comes with a choice of one or two enterprise-class AMD EPYC processors. These processors have earned impressive numbers on tests of demanding workloads running on Apache Spark.

The R7425 offers an adaptable architecture for diverse workloads and environments. In addition, up to 24 hot swappable NVMe drives provide rich storage performance. A greater number of PCIe lanes allows users to combine GPUs with NVMe drives.

User feedback on support is predominantly positive. “Initial setup is straightforward. Their price is reasonable and customer support is good,” said an IT Manager in higher education.

“The technical support is the best, as is the ease of use,” said a Systems Engineer at a scientific organization. “The initial setup is mixed between being straightforward and complex.”


Starting price is $3,729 in the US.
