VxRail dynamic node clusters are compute-only vSphere clusters that allow users to scale compute and storage independently based on workload needs. Built on Dell PowerEdge servers, VxRail dynamic nodes bring all the benefits of VxRail HCI system software with a choice of external storage options. Choose from Dell PowerStore-T, PowerMax, or Unity XT storage systems. By enabling enterprise fiber channel storage to be used as primary storage for VxRail and VCF on VxRail solutions, customers can use dynamic nodes in a three-tier vSphere architecture to support mission-critical data-centric workloads such as SAP HANA.

VxRail dynamic nodes supported for SAP HANA TDI

VxRail dynamic nodes are supported for SAP HANA deployments under the SAP HANA TDI program if:

• All the underlying components (the certified server and certified storage) are supported and listed on the SAP HANA hardware directory
• The VMware vSphere conditions for SAP HANA support are met

Note: VMware vSAN HCI MESH storage is not supported for SAP HANA; therefore, VxRail dynamic nodes are supported for SAP HANA deployments only with certified external storage under the SAP HANA TDI program. VxRail dynamic nodes are not supported under the SAP HCI program.

To verify that the VxRail dynamic node model that you want to use is supported for SAP HANA with external storage:

1. Locate the underlying server chassis for the VxRail dynamic node model in the Dell VxRail Spec Sheet.
2. Verify that the server is listed as a certified appliance or Intel supported server in the  Certified and Supported SAP HANA Hardware Directory.
3. Ensure that the preferred external storage is listed as a certified enterprise storage for SAP HANA in the Certified and Supported SAP HANA® Hardware Directory.
4.  Ensure that the vSphere version and CPU generation of the VxRail dynamic node are supported for SAP HANA. See SAP HANA on VMware vSphere .
