3PAR Active Active Cluster


I have a question about Hp 3par peer persistence,  Can this feature writes data in a  same time with active active in both storage ?  I mean each  host can read and write actively on same lun in both storage.

When I check from Hpe website, What I see, In peer persistence documentations,  Two storages are working like active and passive mode, because it looks one of them is primary and the other is secondary.

I need to know, If it is not working active active cluster. I will  push customer to continue HP XP7 or ıf you recommend other solutions to me, please let me know.

Re: 3PAR Active Active Cluster


Hp peer persistence technology is working little bit different,  It is working one storage primary and other one is secondary. This is not real active active cluster.

In that architecture one storage is primary and all data read and writes transactions directly come primary than it is copying to secondary.  In real active active clusters,  There is no primay and secondary.

 İn real active active storage cluster scenario both storages are working actively and each writes and reads requests from hosts to storages in same time. There is no backround replication.

 For that reason, If you are competing other vendors with active active storage cluster, your choice must be HP XP7. 3par is good product and but ıt does not have real active active storage cluster option.

If you have any question about, please let me know
