Replicação do sistema PI
What you will get:
1.
Ability for clients (ProcessBook) to select among
replicated servers
2.
Changes to configuration data (points, modules)
regularly synchronized between replicated servers
3.
Near-Identical time-series data between replicated
archives (within compression specs)

PI Server Replication
What you will get:
1.
Ability for clients (ProcessBook) to select among
replicated
servers
+ load balancing
2.
Changes to configuration data (points, modules)
regularly synchronized between replicated servers
3.
Near-Identical time-series data between replicated
archives (within compression specs)
(+ no changes to your displays)
