i have question regarding VMware business continuity. As we aware, VMware offer multi writer disk to enable active-active clustering solution i.e Oracle RAC.
However, multi writer doesn't support storage vMotion, cloning and CBT.
I need to ensure my Oracle DB RAC (and others system with multi writer mode) capable to replicate and run to another site via HCX or vSphere Replication without issue.
Can HCX or vSphere replication support this? How ?
Any other solution in VMware can enable the multi-writer kind of system business continuity?
As mentioned before, each of the four HCX migration methods can be used to migrate standalone Oracle workloads, per SLA requirements. Due to the shared disk restriction of HCX migration, Oracle RAC migration is not supported.
Theres a community for HCX discussions now. We’ve worked with customers who achieved a mult-writer migration by sequencing out removing the multi-writer /shared bus elements , then migrating the Oracle RAC members individually with HCX vMotion, then re-assembling the cluster at the destination.
