Abstract
A data management device accessible to a plurality of memories includes a risk unit which determines risk of failure associated with each of the plurality of memories, a selection unit which selects a memory from among the plurality of memories on the basis of the determined risk and a transmitting unit which transmits a replication instruction to another memory of the plurality of memories. The replication instruction causes replication of the data to be replicated that is stored in the selected memory.
Claims15
A data management device accessible to a plurality of memories, the data management device comprising:
- a receiver which receives warning messages from the plurality of memories;
- a risk unit which determines a risk of failure associated with each memory of the plurality of memories on the basis of the received warning messages;
- a selection unit which selects a memory of the plurality of memories based on the determined risk of failure associated with each memory of the plurality of memories, the selected memory storing data to be replicated, the data to be replicated being one of master data and replicated data corresponding to the master data;
- and
- a transmitting unit which transmits a replication instruction to the selected memory, the replication instruction causes replication of the data to be replicated in another memory of the plurality of memories.
A data managing method executed using a data management device accessible to a plurality of memories, the method comprising:
- receiving warning messages from the plurality of memories;
- determining a risk of failure associated with each memory of the plurality of memories on the basis of the received warning messages;
- selecting a memory from among the plurality of memories on the basis of the determined risk, the selected memory storing data to be replicated;
- and
- transmitting a replication instruction to the selected memory, the replication instruction causes replication of the data to be replicated in another memory of the plurality of memories.
A computer readable storage medium storing a data management program to be executed, by a data management device accessible to a plurality of memories, execution of the program causing the data management device to perform a process comprising:
- receiving warning messages from the plurality of memories;
- determining a risk of failure associated with each memory of the plurality of memories on the basis of the received warning messages;
- selecting a memory from among the plurality of memories on the basis of the determined risk, the selected memory storing data to be replicated;
- and
- transmitting a replication instruction to the selected memory, the replication instruction causes replication of the data to be replicated in another memory of the plurality of memories.
