NOTE: In the release notes for Storage Center 7.2 and Storage Center 7.1, the supported maximum storage space for an
SC4020 using a 512 KB page size was incorrectly calculated as 500 TB raw and 400 TB addressable. The correct supported
maximum storage space for an SC4020 using a 512 KB page size is 263 TB raw and 175 TB addressable.
