  • 1.  [Question] Cross VC NSX - Mobility in L3

    Posted May 09, 2019 04:13 AM

    Hello VMwarers!

    While learning NSX in more advanced Designs/Implementations I learned that when we deploy Cross VC NSX now we have a UTZ,ULS and UDLRs good, now we don't have a strectched vSAN cluster across regions/sites suppose we have our clusters within each site no clusters configured between two sites, and the vMotion now works at L3

    The point I can't understand how a host in Site-A will vMotion a VM to another host in Site-B and we haven't any shared Storage?

    vMotion is supported migrating both compute and storage simultaneously. Shared storage is not mandatory. See here: Migration with vMotion in Environments Without Shared Storage

    Other than that vMotion between 2 sites is not the only use case of extending L2 between sites and using Cross-VC NSX. You might also have replication being done between storage on either site so you can recover and bring up VMs on another site without changing IP address.

    I imágened that vMotion always needs a shared storage so the service behind the scenes movies only VM configs from utilizing a host to another one, Now I think the behind the scenes service that provides us the vMotions has privileges to access, creates a shadow copy from the running VM compresses it, moves into another host another storage and then decompresses it running into the new chosen host
