The mirror management console is provided only for the individual mirror resources managed by MCCS.
The mirror management console operates independently from the engine logic of MCCS, so during operation, it can collide with MCCS.
The mirror management console informs users of the mirror volume status and the capacity of the mirror in use. You can change the bandwidth and the mirror network addresses in it.

Compression level

It represents the compression level for a specific copy set. The setting range is from 0 to 9.
‘0’ means no compression. The greater the value is, the smaller bandwidth is used to transmit greater data. But also, it uses more of the CPU resources.
Thus, by properly balancing the system CPU usage and the network bandwidth, select the proper compression level that can maximize the efficiency.

Empty async queue

Even if a driver receives a request for deleting a queue, this function can be used to prevent deletion of queues on a specific volume.
Bandwidth 

It is the max network bandwidth (kbps/sec) that can be used by a copy set.
‘0’ means that the given bandwidth will be used with maximum efficiency.

Mirror network address Copy the volume to the set IP address of data replication between nodes in a cluster.
