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) Linux 2.4 and FreeBSD 4.x, 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 2TB; no additional capacity will be registered. To change this, the unit has to be recreated.
