Floating D2D method of seeding
Many to Once Seeding with Floating D2D target – for large fan-in scenarios
Co-location seeding at Source (remote) sites.
Transport floating target D2D between remote sites then perform replication at the Data Center site.
Repeat as necessary.
1. Initial backup at each remote site.
2. Replication to floating Target D2D over GbE at
each remote site.
3. Move floating Target D2D between remote
sites and repeat replication.
4. Take floating Target D2D to Data Center site.
5. Establish replication from floating D2D Target (now a Source) with Target D2D at Data Center. Delete
devices on floating Target D2D.
Repeat the process for further remote sites until all data has been loaded onto the Data Center Target
D2D. You may be able to accommodate 4 or 5 site s of replicated data on a single floating D2D.
6. Establish final replication with remote sites.
This “floating D2D” method is more complex because for large fan-in (many source sites replicating into single
target site) the initial replication set up on the floating D2D changes as it is then transported to the data center,
where the final replication mappings are configured.
The sequence of events is as follows:
1. Plan the final master replication mappings from sources to target that are required and document
them. Use an appropriate naming convention e.g. SVTL1, SNASshare1, TVTL1, TNASshare1.
