VxRail dynamic node clusters are compute-only vSphere clusters that enable users to scale compute and storage independently based on workload needs. Built on PowerEdge servers, VxRail dynamic nodes bring all the benefits of VxRail HCI system software with a choice of Dell external storage options. Choose from PowerStore-T, PowerMax, or Unity XT storage systems. By enabling the use of enterprise Fibre Channel storage 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 are supported for SAP HANA deployments under the SAP HANA TDI program provided that:
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.
For the VxRail dynamic node model that you want to use, confirm that it is supported for SAP HANA with external storage by:
