* The total capacity values assume that all of the storage pools in the system use the same extent size. 

** Refer to the following shaded box. 

Size limits: If you are using compressed volumes in standard pools, these volumes have the following size limits. If a new or existing compressed volume in a standard pool approaches the maximum size, the system issues an alert. Compressed volumes in data reduction pools do not monitor size of the volumes: 

GLYPH<SM590000> 96 TB 

Maximum virtual size of a new, individual compressed volume. You cannot create a compressed volume that exceeds this size. In addition, you cannot increase the size of a compressed volume beyond this value. If one or more compressed volumes in a system exceed this limit, you receive an alert. To reduce the risk of losing or corrupting data, you must take action soon to remove data from the compressed volume. 

GLYPH<SM590000> 120 TB 

Maximum virtual size of a compressed volume in a system. If any compressed volumes in the system approach or exceed this value, the system issues an alert. 

Immediate action is required to remove all data from the compressed volume and prevent the loss of data. 

GLYPH<SM590000> 128 TB 

Maximum physical size of a compressed volume.
