Страница: 27 / 248

Each node connects through front-end Fibre Channel ports to the backup server,
and through back-end Fibre Channel ports to disk arrays. The network interface
cards enable the nodes to connect to each other and to the ProtecTIER Manager
workstation.
Native replication
Native replication lets you replicate between repositories connected to a wide area
network (WAN) with TCP/IP protocol.
Replication enables you to set rules (depending on your required replication needs)
for replicating data objects across ProtecTIER repositories. The ProtecTIER
repositories can be different in size as well as physical layout. Since ProtecTIER
deduplicates data before storing it, only the changes are transferred to the remote
site. You define the rules for replicating data objects in replication policies on a
repository.
A replication grid is a logical set of repositories that can replicate from one to the
other. The ProtecTIER Replication Manager is a server that remotely manages the
configuration of the grid (for example, grid creation or deletion, repository
membership in the grid, and so on). In most cases, the ProtecTIER Replication
Manager resides on one of the ProtecTIER nodes.
