Hi Keith,  You would need to install splitters on every ESXi host in both clusters. For cluster 1 where the vRPA's reside this is required for journal and repository access. For cluster 2 the splitters are required for write I/O interception.  Regards,  Rich
Hello,   I haven't been able to find a document that talks about adding ESX splitters to an existing RP4VM setup and I saw the following note in one of the guides that looks to maybe contradict? It seems from the supported maximums that the vRPA's of an RP Cluster can reside across a maximum of 2 ESXi clusters. So if I have both vRPA's running on hosts in ESXi_Cluster1 today and I want to add the hosts in ESXi_Clustser2 in order to protect their VM's I would imagine it is just a process of deploying the VIB on those new hosts in ESXi_Cluster2, setting up the vmkernel iSCSI initiators on then, and then adding the vRPA iSCSI targets to the software iSCSI HBA and that would effectively bring in another splitter (named after the cluster) into the RP Cluster - is that correct?  Just trying to plan out expansion possibilities across ESXi clusters to add more hosts in an environment after the initial deployment. [IMAGE]   Thanks!
