Using compression

To help reduce the amount of bandwidth needed to transmit Storage Mirroring Data

Migration data, compression allows you to compress data prior to transmitting it across

the network. In a WAN environment this provides optimal use of your network resources.

If compression is enabled, the data is compressed before it is transmitted from the

source. When the target receives the compressed data, it decompresses it and then

writes it to disk.

By default, compression is set to None, which means it is disabled. The compression

levels can be set at Minimum, Medium, or Maximum. Each level requires more

overhead than the previous level of compression. If you notice an impact on performance

while compression is enabled in your environment, either adjust to a lower level of

compression or leave compression disabled.
