Notes #20 Volumes over 108 TB require 32 GB of memory or more.Actual maximum storage pool and volume sizes depend on drive sizes used, the number of drive bays available, and the RAID configuration.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.Storage efficiency helps reduce storage space consumption through deduplication and compression.
