HYBRID DATA REPLICATION

摘要

A system for accelerating database transaction processing by controlling data replication is provided. The system includes a first control unit configured to manage a first storage device and at least one second control unit configured to manage a second storage device. The first control unit writes first data to the first storage device and sends the first data to the second control unit in response to receiving from a host a first write command including the first data. The first control unit writes second data to the first storage device without sending the second data to the second control unit in response to receiving from the host a second write command. The second control unit writes the first data to the second storage device in response to receiving the first data. The second control unit writes the second data to the second storage device in response to receiving from the host a third write command.

1. A system for controlling data replication, comprising:
a first control unit configured to manage a first storage device by:
in response to receiving from a host a first write command including first data, writing the first data to the first storage device and sending the first data to a second control unit; andin response to receiving from the host a second write command including second data, writing the second data to the first storage device without sending the second data to the second control unit; and the second control unit configured to manage a second storage device by:
in response to receiving from the first control unit the first data, writing the first data to the second storage device; andin response to receiving from the host a third write command including the second data, writing the second data to the second storage device.
