Instructions:

 

 

Note: Downgrading DDVE size is not supported. Only upgrades are supported.   

      When there is an upgrade of DDVE size, CPU and memory reservation must also be upgraded based on the configuration.   
   
      Taking DDVE snapshot while it's running is not supported. Shutdown DDVE before taking a snapshot.     
          
   
      To find if current DDVE configuration is supported:# system vresource show currentThis configuration is not supported. Check the resource requirements for supported configurations.    
   
    If the configuration is not the same as in the below tables. Please shutdown DDVE and make the required changes.

    We recommend users start with 1 TB metadata tier and use 1 TB as incremental size.       
        Note: If DDVE has only one cloud unit then it can be twice as large as Active tier, unlike DD where a cloud unit can only be as large as Active tier.         
          However, Cloud Unit (CU) size in the below table includes both cloud units.

The metadata requirements that are listed for supported virtualization platforms are based on 10X dedup ratio and 2X compression. Your system configuration may require a higher storage ratio. Please expand the storage if you receive an alert asking you to do so.

      ATOS Metadata storage capacities     
      The recommended metadata capacities are 10% of the licensed capacities. We recommend the first metadata disk to be of a minimum of 1 TB and increments of at least 500 GB.         
          Command to check the current metadata size
# filesys show space tier active local-metadata        
        The following table is recommended metadata storage sizes for various capacities. The metadata requirements that are listed for supported virtualization platforms are based on 10X dedup ratio and 2X compression. Your system configuration may require a higher storage ratio. Please expand the storage if you receive an alert asking you to do so.
