VxRail dynamic nodes are VxRail systems that are compute-only nodes used to form a vSphere cluster. Dynamic node clusters rely on external storage resources for its primary storage. External storage resource types can be remote datastores from vSAN clusters using VMware vSAN HCI Mesh or datastores from Fibre-Channel attached storage on Dell EMC storage arrays such as PowerStore-T, PowerMax, and Unity XT. Dynamic node clusters further extends the workload types that VxRail can address. Customers can now deploy VxRail for workloads that may require enterprise storage-level data protection and resiliency or can benefit from independent scaling of compute and storage for better cost economics. Customers can continue to store the workloads on an enterprise array while benefitting from VxRail’s simplified lifecycle management. For applications that may be compute-intensive or storage-intensive, VMware vSAN HCI Mesh allows customers to use a mix of compute clusters and vSAN clusters that can result in better resource utilization and optimized license costs. When VxRail is used to form vSphere clusters and vSAN clusters, customers can benefit from a common operating model with VxRail HCI System Software.
VxRail dynamic nodes are compute-only nodes running ESXi. There is not support for internal storage, therefore a vSAN license is not required. VxRail HCI System Software is responsible for the lifecycle management of the node. Lifecycle management of the storage array is separate. VxRail dynamic nodes are available with the E560F, P570F, and V570F VxRail models. All configuration options that come with these models are available except for cache and capacity drives.
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.
Intel Inside®. Trusted clouds outside.
Intel innovation is driving the modernization and hybrid cloud transformation of the traditional enterprise datacenter.
Migrating to the newest generation of high-performing and energy-efficient Intel-based hardware tunes a datacenter for highly optimized performance across a broad set of enterprise workloads while lowering costs and improving resource utilization.
Over time, evolving to a software-defined infrastructure (SDI) across all the critical domains of the datacenter (compute/storage/network) will deliver critical automation, orchestration, and telemetry capabilities to help businesses unlock the full capabilities of multi-cloud computing.
With modern, industry-standard Intel® servers and technologies that run on software-defined infrastructure, customers can seamlessly manage an environment that supports development and delivery of cloud-native applications and mission-critical workloads on secure private clouds, while also integrating with public clouds, many of which already run on Intel® architecture.
With up to 40 cores delivering highly enhanced per core performance, significant increases in memory bandwidth (eight memory channels) and I/O bandwidth (64 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.
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.
AMD Infinity Architecture is the foundation of AMD processor technology. A thoughtful design approach to accelerate computation, access data quickly, and help protect against ever-changing security threats. AMD have brought many firsts to the market:
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™, single-socket servers satisfy many workload needs, helping increase density and reduce capital, power, and cooling expenses.
PowerEdge servers are optimized for the 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 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 (most but not all node types). 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.
