VxRail nodes are available with different compute power, memory and cache configurations to closely match the requirements of new and expanding use cases. As requirements grow, the system easily scales out and scales up in granular increments.
Dell EMC delivers the #1 hyper-converged infrastructure portfolio purpose-built for HCI with the newest Dell EMC PowerEdge server platform. This portfolio delivers tailor-made performance and reliability powerful enough for any workload, combined with an advanced approach to intelligent deployment and operations that simplify and accelerates IT. Dell EMC HCI on next gen PowerEdge servers are powerful and purposeful and hyper-converged platforms that provide the ideal foundation for software-defined data center initiatives.
With up to 150 customer HCI requirements built-in, PowerEdge servers are designed specifically for and tailored to HCI workloads that depend on both servers and storage. This results in a more consistent, predictable and reliable high-performing HCI that can meet any use case. With a comprehensive portfolio, Dell EMC can deliver the best fit for organization specific HCI needs – from workload requirements, to customer environment/standardization, to deployment preferences.
Dell EMC leads in hyper-converged sales with over 30% market share, according to IDC converged Tracker Q1 2018, June 2018. More customers are choosing Dell EMC HCI over all others. Dell EMC PowerEdge is the world’s bestselling server. Industry-leading Dell EMC HCI built on industry-leading PowerEdge, coupled with a single point of support and full lifecycle management for the entire system, makes for a winning solution.
VxRail environments are configured as a cluster, with each node containing internal storage drives. VxRail systems are delivered with the software loaded, ready to attach to a customer-provided network. While most environments use 10Gb Ethernet for internal and external communications, 25Gb Ethernet connectivity is also available. Using a simple wizard at the time of install, the system can be configured to match unique site and networking requirements.
Dell EMC VxRail appliances offer a choice of Dell EMC PowerEdge servers, powered by new Intel® Scalable® processors, variable RAM and storage capacity, allowing customers to purchase what they need now. Single-node scaling and storage capacity expansion provide a predictable, “pay-as-you-grow” approach for future scale up and out as business and user requirements evolve.
Figure 19 shows the comprehensive set of options available across the family as of the writing of this paper. 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 model series family. More information on VxRail hardware configurations is available in the Dell EMC VxRail System TechBook.
VxRail’s automated lifecycle management enables scale out where new appliances can be added non-disruptively and different models can be mixed within a VxRail cluster. By adding the latest technology appliances into existing clusters and decommissioning aging appliances, an evergreen HCI environment can be obtained; no need to worry about costly SAN data migrations ever again. Flexible storage options also allow a node to start with a few drives and add drives as capacity requirements grow. Appliances may also be scaled-up where the VxRail nodes can be non-disruptively upgraded with additional memory, GPU, NIC cards, cache SSD and capacity drives to meet changing requirements. Single-node scaling and expansion provide a predictable, “pay-as-you-grow” approach for future scale up and out as business and user requirements evolve.
VMware Cloud Foundation on Dell EMC VxRail can be delivered as either a cluster of appliances that leverages the customer’s existing network infrastructure, or an integrated rack system with integrated networking as shown in Figure 20.
Figure 20. VxRail delivery options
For customers that would like to get their VCF on VxRail solution delivered as a rack integrated system, Dell EMC has available a set of rack assembly services that customers can purchase that leverage the power of the Dell 2nd Touch facility global footprint to incorporate additional factory services as part of VCF on VxRail delivered solution. With Flexible 2nd Touch Facility factory services, customers have options on the rack and networking components they would like used. Customers can purchase from Dell, a rack from our Dell partner, APC, or supply their own consigned 3rd party rack. Customers also have options relating to network switches as well. Customer can purchase Dell EMC PowerSwitch with OS10 EE switches from Dell EMC or they can supply their own consigned 3rd party switches. Any 3rd party consigned items supplied by the customer must be purchased separately by the customer outside of Dell EMC. Support for those components would be provided by the component vendor and not from Dell EMC. So, depending on which components are used for the system, a customer will have a choice of what support experience they would like to have.
Dell EMC also offers fixed scope services that integrate a fixed configuration VxRail Integrated Rack using Dell EMC PowerSwitch Networking with OS10 Enterprise Edition and Dell EMC supplied rack from the partner, APC. With a VxRail Integrated rack using Dell EMC switches, customers can obtain a single vendor support experience for their VCF on VxRail solution. Dell EMC would provide single call support for VxRail and networking HW, as well as single vendor support for the Cloud Foundation software.

Fixed rack design configuration option for VxRail Integrated Rack deployments are a set of specific hardware and software requirements that have been tested and validated by Dell EMC. Customers who are looking for a racked and stacked VxRail system, with VMware Cloud Foundation and no specific networking hardware vendor or model requirements could select from this option.
Flexible rack design configuration option for VxRail Integrated Rack deployments are available for all customer requirements outside of Fixed Configuration options. This option is for customers looking to adopt VCF on VxRail using heterogenous models, require specific networking hardware vendor equipment, and/or no networking at all.
