Dear Community Gurus,
I have a customer with a FAS2040A at primary site and a FAS2040 at DR site, WAN pipe size is 6Mpbs. He has a 3TB volume at primary that he wants to SnapMirror to DR, but the WAN pipe is only 6Mbps so initializing over
the WAN is not a very good option. SnapMirror to tape is not a good option either because of the cost of a fiber library and limited fiber ports on primary controllers. They do, however, have an extra DS4243 shelf with 12x1TB drives at their disposal. Would it be possible to use this extra shelf to SnapMirror the data locally, then ship the shelf to the DR location, and resync the mirror?
Here's how I'm thinking it would go:
- Attach DS4243 to primary site FAS2040A
- Create a new aggregate
- Create a new volume on the aggregate
- Initialize SnapMirror relationship from existing
3TB volume to newly created volume on new aggregate - Quiesce and break relationship
- Offline new volume and aggr
- Remove shelf, ship it to DR site
- Attach DS4243 to DR site FAS2040
- Resync SnapMirror relationship
Looking for some help to know if this is even possible to do. If so, I know there will be some disk ownership considerations. For example, do I remove the ownership of the drives before I remove it from the FAS2040A, or do I wait until the shelf gets to the DR site? I know there will also likely be some foreign aggr/volume considerations as well.
Again, any and all feedback is GREATLY appreciated.
Thanks
Dennis
