The VxRail system is assembled with proven server-node hardware that has been integrated, tested, and validated as a complete solution by Dell EMC. All the nodes in the current generation of VxRail use either Intel Xeon Scalable family processors or 2nd Gen AMD EPYC processors. The number of cores and memory capacity differ for each VxRail model.
Each node server includes the following technology:

Intel® Xeon® Scalable platforms are powerful infrastructure that represents an evolutionary leap forward in agility and scalability. Disruptive by design, it sets a new benchmark in platform convergence and capabilities across compute, storage, memory, network and security. An innovative approach to platform design in Intel® Xeon® Scalable processors unlocks the power of scalable performance for today’s datacenters and communications networks—from the smallest workloads to the most mission-critical applications.
With up to 28 cores delivering highly enhanced per core performance, and significant increases in memory bandwidth (six memory channels) and I/O bandwidth (48 PCIe lanes), the most data-hungry, latency-sensitive applications such as in-memory databases and high-performance computing will see notable improvements enabled by denser compute and faster access to large data volumes. And the latest generation processors designated with an ‘M” can support denser memory, with up to 1536GB per processor.
The convergence of compute, memory, network, and storage performance combined with software ecosystem optimizations make Intel® Xeon® Scalable platforms ideal for fully virtualized, software-defined datacenters that dynamically self-provision resources—on-premises, through the network, and in the public cloud—based on workload needs.
2nd Gen AMD EPYC™ are a new breed of server processors which have set a higher standard for data centers. AMD have brought many first to the market with this processor generation:
AMD EPYC™ has been engineered for data centers that rely on CPU performance. From oil and gas exploration, to in-memory databases, to big data analytics to production rendering to standard data center applications, highly parallel workloads have more cores to work with. Traditional CPUs typically must scale up to a 2-socket server to overcome an imbalance of resources. With AMD EPYC™, 1-socket servers satisfy most workload needs, helping increase density and reduce capital, power, and cooling expenses.
PowerEdge servers are optimized for the 2nd Gen AMD EYPC processors taking advantage of the additional cores, faster and additional memory channels, and of PCIe 4.0 for faster networking.
Storage capacity for the VxRail system is provided by drives that have been integrated, tested, and validated by Dell EMC. VxRail configurations use 2.5” form-factor SSDs, 2.5” NVMe drives, and mechanical HDDs. There is a VxRail configuration that uses 3.5” form-factor drives which also available for dense-storage requirements. Disks drives are logically organized into disk groups. Disk groups are configured in two ways:
The flash drives used for caching and capacity have different endurance levels. Endurance level refers to the number of times that an entire flash disk can be written every day for a five-year period before it has to be replaced. A higher-endurance SSD is used for write caching, and capacity-optimized SSDs are used for capacity. All VxRail disk configurations use a carefully designed cache-to-capacity ratio to ensure consistent performance. Capacity SSDs are offered in both higher endurance SAS and SATA. The SATA SSDs are a lower cost option, up to 30% per drive, and great for read or moderately intensive workloads.
All-NVMe configurations are available in the E560N, E665N and P580N which use either Intel Optane or NVMe drives for cache, and NVMe drives for capacity. The E560N is a cost-effective 1U platform that can support a variety of workloads including data warehousing, database, and analytical workloads with its support for Nvidia T4 GPUs. The P580N is the only 4-socket VxRail offering. Combined with all-NVMe storage, it is an ideal platform for memory-intensive and compute-heavy application workloads.
VxRail nodes can be configured with choice of processor, memory, storage (cache and capacity drives), networking, power supply, and GPU (in the E, V and D Series only). Customers can be assured their VxRail is configured to best match their workload requirements in a very prescriptive manner, with millions of possible configuration combinations in the VxRail Series. Combine this with the numerous ways to scale on demand, and it is clear that VxRail provides the agility demanded by today’s modern IT. Upgrade options for VxRail include, memory, GPU, NIC cards, cache, and capacity drives expand workload use case possibilities.
