Notes    
Usable capacity for each volume will be lower than the maximum volume size and is dependent on the filesystem and the amount of system metadata stored.
When Peta Volume is enabled, validated services and packages are required. Please refer to this article for more information on limitations.
Actual maximum storage pool and volume sizes depend on drive sizes used, the number of drive bays available, and the RAID configuration.
Volumes over 108 TB require 32 GB of memory or more.
