Let's take all host based options off the table (LVM, PPME, ASM, OM, Backup/Restore ..etc). Let's pretend that my entire environment consists of two XtremIO arrays and that's it. No RecoverPoint, no VPLEX ..no nothing. I need to migrate a physical server from one XtremIO to another, what are my options ? Could i use vRPA since my iSCSI ports are not in-use ? Again this is for migration only, not for continues replication.
I initially asked about vRPA's when the RP/XtremIO solution was released and was informed it was not supported with iSCSI back to the the XtremIO's. That was about 2 months ago and not sure if the stance has changed. With that being said, it could just be an RPQ route now. I would suggest to post this query in the RP ECN space as those CSE's will be able to field the question and any follow-up that can be discussed.
In your situation, I have had to deal with that a couple times and utilize host-based methods all but once (where the customer had physical RP running and it was a CDP copy).
I cannot really comment on the roadmap items in this forum, but at this time the host based options are the only ones available (for the scenario mentioned above).
