Configuring Geographic Mirroring (7.4)
PowerHA Geographic Mirroring replicates independent auxiliary storage pool (IASP) via IBM i networking. As the system writes data from main memory to disk, the same data is sent over TCP/IP to the target system to be written to disk, ensuring identical data between both systems. As a result, Geographic Mirroring provides the same simplicity as SAN-based replication, with the flexibility to work with any storage (internal or external), and is highly efficient.
PowerHA in a Hybrid Cloud Environment
Geographic Mirroring supports replication between two nodes across two different sites. Replication can be either synchronous or asynchronous.
