Compressing data to save storage space

You can use server-side data compression to increase the amount of available space in a storage pool.

About this task

Review the following table to compare client-side and server-side compression:

Type of compression Advantages Disadvantages
Client-side
  • Reduced load on the network
  • Reduces data that is stored in the storage pool
  • Higher processor usage by the client
  • Potentially longer elapsed time for client operations such as backup
Server-side
  • Uses inline compression to compress data as it is written to a container storage pool
  • Reduces the amount of space that is required to store the data
  • Does not affect on client operations such as backup
  • No load reduction on the network
  • Higher processor usage by the server

Procedure

Inline compression is enabled by default. To disable compression, issue the UPDATE STGPOOL command and specify the COMPRESSION=NO parameter.
