Support for Over 2 Terabytes
Legacy operating systems such as Windows 2000, Windows XP (32-bit),
Windows 2003 (32-bit and 64-bit without SP1), and Linux 2.4, do not
recognize unit capacity in excess of 2 TB.
If the combined capacity of the drives to be connected to a unit exceeds 2
Terabytes (TB), you can enable auto-carving when you configure your units.
Auto-carving divides the available unit capacity into multiple chunks of 2 TB
or smaller that can be addressed by the operating systems as separate
volumes. The carve size is adjustable from 1024 GB to 2048 GB (default)
prior to unit creation.
If a unit over 2 TB was created prior to enabling the auto-carve option, its
capacity visible to the operating system will still be 2 TB; no additional
capacity will be registered. To change this, the unit has to be recreated.

Note: All drives in a unit must be of the same type, either SAS or SATA.
