For any Azure Stack HCI cluster expected to deliver high performance, administrators need to rely on specially trained experts who can help accelerate time to value and decrease mean time to resolve (MTTR) failures. Dell Technologies makes services simple, flexible, and worry free – from installation and configuration to comprehensive single-source support. Certified deployment engineers ensure accuracy and speed, reduce risk and downtime, and free IT staff to work on higher value priorities. One-stop cluster level support covers the hardware, the operating system, the hypervisor, and Storage Spaces Direct.
When it comes to expanding clusters, customers can choose to follow the prescriptive guidance in the Operations Guide or enlist the help of our support and services. In addition to improving the storage performance of the cluster, adding AX nodes increases storage capacity and provides more compute resources to the VMs. Administrators must verify hardware symmetry before attempting any expansion operations. This means that the processor model, HBA, and network adapter configuration in the new AX node must be identical to the existing nodes.
For the full list of requirements for scaling out the cluster to include additional nodes and scaling up existing nodes, see the Operations Guide.
