I would like to know if anyone has done a configuration like this ? What can be the technical pain points ?
NetApp filer behind HDS virtualized and Shadow Image to the NetApp Block storage .
- Connect a suitable netapp filer into the dedicated external SAN
- Create block devices (LUNs) on the filer of exactly the same size as the primary devices, and present as external devices to the SAN array. The LUN’s should all sit within a dedicated netapp volume
- Create a shadow-image relationship between the primary storage and the virtualised netapp devices. Split off. This should occur before the nightly snapshot of the netapp volume
- Restore approach to be snaprestore of the netapp volume, followed by a shadowimage restore.
