Hi Keith, 1) The CG is identifiable but the snaps and snap sets are only visible through the user rp_user which is a special user reserved for RP operations. The XMS is registered in the RP using that user. 2) 500 snaps per volume is the maximum, less can be configured on a per RP copy policy basis. each PiT on RP is a snap on the target XtremIO array. The user can see these snaps through RP's journal tab under the target copy. From the XtremIO CLI, these snap volumes will show up as internal volumes as they are visible only through rp_user. a) All aspects of snapshot management in XtremIO are automatically managed by RP, nothing should be created automatically. This relates to both source and target arrays. 3) I'll get the TN fixed, there's no need to create CG but there's a need to register the RPAs and mask volumes (production, journals, repository, etc.) to them. With RP 4.1.2 and XtremIO 4.0, it's supported to have a max of 64 volumes per RP CG 4) So, in image access with XtremIO at the target, the PiT data isn't in journal. The Journal contains only metadata. the PiT is actually a snap on the target XtremIO array. Every time a snap is created in XtremIO, another volume (besides the derivative snap) is created, referencing the snap. That volume has an external SCSI personality, which means it can be exposed to a host.  Hope that helps, Idan Kentor Corporate Systems Engineering - RecoverPoint and VPLEX
Hi,  I am cross-posting this from the XtremIO ECN site since there have been no responses provided:  Hello,   After reading the integration technote with XtremIO and RecoverPoint, I have some clarification questions I am seeking some confimraiton/answers to please:  XtremIO-to-XtremIO Replication is assumed here:  1. When XtremIO is the source array, there looks to be about 2 snaps at any given time and an auto-created XtremIO CG for the volume being protected with RP – are these snaps/CGs identifiable in the XtremIO GUI or under the covers? How would a user query these?  2. When the XtremIO is the target array, there can be a max of 500 snaps created – are these XtremIO snapshots that are created identifiable in the XtremIO GUI or under the covers? How would a user query these?        a. Is there an XtremIO CG auto-created on the target XtremIO array with this solution for any failover tasks that might occur, or just the      source XtremIO array?  3. The technotes have a step for the user to create an XtremIO CG and put in all of the volumes that RP will replicate: “On the XtremIO management server, create an consistency group that contains all XtremIO volumes involved in RecoverPoint replication.”  >>> Why is this needed if RP will automatically create the XtremIO CG’s per RP CG?  >>> How is the limit of 256 volumes per XtremIO CG handled in this setup? Just create multiple XtremIO CG’s to handle 256 volumes each?  4. There is a snippet on how image access is handled in the technote: “The array actually presents a copy of the snapshot. The original snapshot is not affected. Replication and distribution continue, unaffected by the image access.”  >>> Does this mean that for the snapshot created on the target array that the user selects in RP's journal, another XtremIO snapshot is created for host presentation since it presents a copy of the snapshot? If so, do these “copies” get accounted in the overall snapshot limits of the array? This is a little different verbiage than earlier in the document which just says it access the actual snapshot so I'm trying to see if it really creates more or not here.   Thanks!
