FluidFS Replication

Note the following information regarding FluidFS replication:

Replication can be performed from FluidFS v4.x to FluidFS v5.x. As a best practice, replication between systems running different major versions should be performed only for short-term update scenarios and is not recommended as a normal operating state.
Replication partners can differ in network interface speeds (1GB or 10GB) or in memory size (24 GB or 48 GB).
The FluidFS version determines the way replication is performed, specifically the TCP ports that are used to communicate between the replication partners. See #GUID-ECB21515-CAAB-4B6D-B083-BAB995104E59__GUID-8E589052-4F6A-4736-A041-3834EA683174 for the TCP ports used by each replication protocol level.

#GUID-ECB21515-CAAB-4B6D-B083-BAB995104E59__GUID-C558BC3B-377D-4497-B0FA-EA5D5C105556 lists replication-compatible systems, assuming they satisfy all other conditions

Table 1. Supported FluidFS Replication Features
Attribute	Support
Maximum number of replication partners	100
Maximum number of replicated NAS volumes	1024
Maximum number of concurrent replications (rest are queued)	10 outgoing and 100 incoming
Maximum replication schedules (as source)	1024
Maximum number of replication bandwidth limiter policies	1023
Single NAS volume to single NAS volume	Yes
Single NAS volume to multiple NAS volumes	No
Cascading replication of a NAS volume	No

FluidFS replication requires that the target-system TCP ports listed in #GUID-ECB21515-CAAB-4B6D-B083-BAB995104E59__GUID-8E589052-4F6A-4736-A041-3834EA683174 be accessible, through the firewall, from the source system.

NOTE: For FluidFS v5.x systems replicating to FluidFS v5.x systems, only one TCP port (10560 or 3260) needs to be opened in the firewall for all replication functions.
