Site locations

Site locations

  • The requirement for multiple site locations for Cloud Foundation on VxRail deployments affect the overall high-level design. Factors such as distance and the quality of the network between sites must be considered.

    • The management of multiple sites from a single management instance has network guidelines that must be met for supportability.
    • The migration of virtual machines between sites using vMotion has network guidelines that must be considered for supportability.
    • Both private and public WAN connections are supported for Cloud Foundation on VxRail provided compatibility requirements are met.
    • Considerations for SD-WAN are merited for deployments spanning across multiple remote sites.

    Primary and secondary active WAN links are strongly recommended. Without network redundancy, you might encounter conditions that can lead to failure states such as a two-failure state condition, which can result in unrecoverable virtual machines and application failure.
