Configuring compression
To help reduce the amount of bandwidth needed to transmit Storage Mirroring 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 uncompresses it and then writes it to disk. On a default Storage Mirroring installation, compression is
disabled.
Keep in mind that the process of compressing data impacts processor usage on the source. 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. Use the following guidelines to determine whether you should enable compression:
If data is being queued on the source at any time, consider enabling compression.
If the server CPU utilization is averaging over 85%, be cautious about enabling compression.
Exchange Server data is typically highly compressable, so it is recommended that compression be enabled at level 2 on
Exchange Server solutions.
Do not enable compression if most of the data is inherently compressed. Many image (.jpg, .gif) and media (.wmv,
.mp3, .mpg) files, for example, are already compressed. Some images files, such as .bmp and .tif, are uncompressed,
so enabling compression would be beneficial for those types.
Compression may improve performance even in high-bandwidth environments.
1. Right-click the connection on the right pane of the Management Console and select Connection Manager.
2. Select the Compression tab.
3. By default, compression is disabled. To enable it, select Enable Compression.
4. Depending on the compression algorithms available for your operating system, you may see a slider bar indicating
different compression levels. Set the level from minimum to maximum compression to suit your needs.
5. Click OK to save the settings.
NOTE: Compression is a per target option. All connections to the target will have the same compression configuration.
