Is it possible to create Peer Persistence between a nimble HF20 and an Alletra 5030?

Hi Cmorales1,

Yes, the Peer Persistence is possible to create between an Alletra 5030 and a Nimble HF20.
Peer Persistence ensures high availability and data redundancy by synchronously replicating data between two storage arrays.

Hope this helps.

@Satish04 Thank you! can you clarify if the syncronous replication is also posible between those devices?

Gracias por tus respuestas. Según pensaba sí se podía pero tú lo has visto ser aplicado? es que según un documento que vi de HPE, sí se puede pero solo de forma asíncrona debido a las capacidades que tiene el Alletra en comparación con el Nimble HF20, aparte encontré otra respuesta informal de HPE en uno de estos foros en la que se explicaba que no se puede. Podrías darme más contexto de si es posible?

Thanks for your answers. I thought it could be done, but have you seen it being applied? is that according to a document I saw from HPE, yes it can but only asynchronously due to the capabilities that the Alletra has compared to the Nimble HF20, apart from that I found another informal response from HPE in one of these forums in which it was explained It is not possible. Could you give me more context on whether it is possible?

Peer persistence requires to work with the same model. So that the performance of the volume is equivalent when a failover occur. 

HF20 to HF20. 

Likewise, 5030 to 5030.

Gracias. Hasta donde entiendo así es, por lo que no sería posible hacer failover automático entre Nimble y Alletra de esos modelos, es correcto? y tampoco una replicación síncrona. Pero no he tenido mayores respuestas definitivas hassta ahora. Solo queremos asegurar si es posible (ya se ha logrado) o no (se intentó y no se pudo).

Thank you. As far as I understand, this is the case, so it would not be possible to do automatic failover between Nimble and Alletra of those models, is that correct? and not synchronous replication either. But I haven't had any more definitive answers until now. We just want to ensure if it is possible (it has already been achieved) or not (it was tried and failed).

That is correct, with mixed model, you cannot have sync replication and no automatic failover.

@BoonL What happens with intensive workloads which are pinned in cache between 2x Alletra 5030? Are these also available in synchronuous relication?
