Understanding RAID Levels and Concepts Support for Over 2 Terabytes Windows 2000, Windows XP (32-bit), Linux 2.4, and FreeBSD 4.x, do not currently 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 MB to 2048 MB (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. For more information, see "Using Auto-Carving for Multi LUN Support" on page 31. www.3ware.com 19

Support for Over 2 Terabytes
Windows 2000, Windows XP (32-bit), Linux 2.4, and FreeBSD 4.x, do not
currently 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 MB to 2048 MB (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.
For more information, see “Using Auto-Carving for Multi LUN Support” on
page 31.
