vSAN is deployed, scaled, and life-cycle-managed with SDDC Manager and VxRail HCI System software automation. WLDs with VxRail vSAN clusters can be configured quickly and can be ready to use without having to make complex changes within VxRail hardware. vSAN Storage Policy Based Management (SPBM) allows for storage characteristics such as primary failures to tolerate and disk striping. Storage settings can be changed in software at a VM or object-level nondisruptively with only a few clicks. Compare vSAN with traditional array-based storage, which often requires hardware changes and updates across a whole LUN or volume through processes that are often time consuming and risky.
