network-based disaster recovery protection, and it lets users combine
rapid, local restores with sound disaster recovery protection.
With DXi-Series replication, users can transmit data from a single site or
multiple sites to a central location using any DXi model. DXi-Series
replication is an asynchronous, automated background process that
includes encryption of data in transit. This model for protecting the
distributed enterprise allows users to combine disk, replication, and
tape for an optimal combination of performance, simplicity, and
security.
For more information on implementing a replication plan, see
Chapter 6, DXi4701 Replication .
Note: A DXi4701 can only replicate data to a DXi that supports the
same protocol as the DXi4701 (NAS or VTL). That is, a DXi4701
NAS system can only replicate data to a DXi that supports NAS.
Similarly, a DXi4701 VTL system can only replicate data to a DXi
that supports VTL.
