Wastewater operations wants shared storage for the municipal cluster from host disks so the county can skip buying a new SAN. Which VMware SDDC product is that storage pillar?

Wastewater operations that want shared storage for the municipal cluster from host disks—so the county can skip buying a new SAN—need vSAN, the software-defined storage pillar of the VMware SDDC. vSAN aggregates local disks in the wastewater hosts into a shared datastore that clusters can consume for VM disks, which is exactly the civic hyperconverged storage use case. NSX-T Data Center virtualizes networking with overlay, routing, and firewalling; it does not present a hyperconverged block datastore from host disks and cannot replace a SAN purchase with packet fabric alone. Horizon publishes virtual desktops and apps for end users; it is not the storage product that pools host disks. Carbon Black provides endpoint and workload protection analytics and prevention; it never becomes shared VM storage for wastewater historians or SCADA jump hosts. Exam caveat: vSAN still runs on vSphere hosts and uses networking for disk I/O between nodes; needing a VMkernel network for vSAN does not turn NSX into the storage pillar. Associate depth is naming vSAN as the storage product, not designing disk-group sizing or FTT policies on the exam. Operational check: confirm hosts have claimed disks in vSAN disk groups, a vSAN datastore is mounted to the cluster, and a wastewater VM can place VMDKs there without a traditional external SAN LUN for that use case; verify vSAN health is green before cutting over production disks. Keep that validation screenshot with the cluster design package so finance sees host-disk pooling—not a silent return to SAN procurement—for wastewater shared storage.
