An overview of VMware vSAN on VxRail
VMware vSAN is a Software-Defined Storage (SDS) solution that is used in collaboration with the VMware vSphere hypervisor. The VMware vSAN solution can provide shared storage for VMs. In Figure 4.1, vSAN is a vSphere cluster feature that virtualizes the local physical storage in the pool of the Hard Disk Drive (HDD) and Solid-State Drive (SSD) on the ESXi hosts in a cluster, building them into a unified data store. Each ESXi host requires a minimum disk group that includes a SSD and HDD. vSAN can provide enterprise storage that is powerful, flexible, and user-friendly. This solution can be deployed in different environments – for example, the core, the edge, and the cloud. When you build the VxRail cluster on day one, the vSAN datastore is created automatically.
The vSAN datastore includes the following characteristics:
- All nodes in the VxRail cluster must be connected to a vSAN Layer 2 or Layer 3 network. It supports a maximum...
