Optional. This parameter specifies whether the Thin Provisioning function is enabled. If this

Optional. This parameter specifies the maximum capacity of the pools (the total capacity of the
TPPs and the FTSPs) that can be created in the ETERNUS DX. If this parameter is omitted, the
existing setting remains unchanged.
The values that can be specified for each model are shown below.
ETERNUS DX100 S3/DX200 S3: 32tb, 64tb, 128tb, and 256tb
ETERNUS DX500 S3: 64tb, 128tb, 256tb, and 384tb
ETERNUS DX600 S3: 128tb, 256tb, 512tb, and 768tb
ETERNUS DX200F: 32tb
• This parameter can only be specified when the Thin Provisioning function is used.
• The maximum capacity can only be expanded from the current maximum capacity.
• The actual pool capacity (logical) that can be used varies depending on the drive capacity
(physical). For example, if an ETERNUS DX200F has twenty-four 800GB SSDs installed, even
though 32TB is specified for the parameter, the usable capacity is limited to 16TB.
