SRA configuration for M–N Metro Mirror
M–N Metro Mirror enables peer-to-peer remote copy (PPRC) connections from a
protected (primary) DS8000 SRA to more than one recovery (secondary) DS8000.
Each PPRC connection is stand-alone. Therefore, a volume on a protected DS8000
having a PPRC with a recovery DS8000 can also have a PPRC from a different
volume to a different recovery DS8000.
M–N Metro Mirror also enables connections from a recovery DS8000 SRA to more
than one protected DS8000 SRA.
Note: The term "M–N" refers to the number of DS8000s on the protected site (M)
and recovery site (N). No calculations are derived from this term. M–N is only
used to denote the replication process.
The SRA processes the PPRC connections separately, and each PPRC connection
can be reversed.
