Using vSphere vMotion feature the migration of VMs to different clusters can be easily done with no services interruption and with no need to work during off-work hours or during the weekend. Filed under: Software by Paolo Valsecchi.
What is Software-Defined Storage? Why All-Flash Exactly? Home StarWind Blog vSphere 6. Requirements for vMotion without shared storage To perform a successful migration across clusters with no shared storage, the infrastructure must be configured accordingly in order to ensure all involved components can communicate. Scenario: hot migrate VMs from vSphere 5. Prerequisites Once the new 6. Make sure the ESXi version installed in the source cluster is included in the supported matrix: If the ESXi hosts in the source infrastructure to migrating are installed with an old version for example version 5.
In this example, you need to upgrade the hosts 5. The hardware in use must be verified in the compatibility matrix to ensure it is actually supported by the vSphere version installed in the target infrastructure. Upgrade the source infrastructure In the chosen scenario, the source vSphere cluster is version 5.

You cannot use RDMs on local storage see limitations , shared storage is required. Virtual storage appliances on local disks using iSCSI can be looped back to support this not recommended for tier 1 applications. In guest backup agents can be used but be aware that you may need to create a separate virtual machine port group for backups, unless you want backups to be transported over your VM network! What type of infrastructure will be available to support the workload at your recovery site?
Have you accounted for the clustered application itself? Lastly it goes without saying make sure your disaster recovery documentation is up to date. Benefits: If architected correctly with VMware vSphere, a virtual implementation can meet the demands for tier 1 applications. Can reduce hardware and software costs by virtualising current WSFC deployments. Taking into account the limitations stated above, in my opinion the biggest drawback is the high operational overhead involved with looking after virtual WSFC clusters.
WSFC solutions can be complex to manage. Keep the solution simple! Like this: Like Loading Leave a Reply Enter your comment here Please log in using one of these methods to post your comment:. Email Address never made public. Follow Following.
