Introducing the 3ware® SAS/SATA RAID Controller down to 120 GB. For more information, see the discussion of drive coercion under "Creating a Hot Spare" on page 113. Note: All drives in a unit must be of the same type, either SAS or SATA. Support for Over 2 Terabytes Windows 2000, Windows XP (32-bit), Windows 2003 (32-bit and 64-bit without SP1) and 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 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. For more information, see "Using Auto-Carving for Multi LUN Support" on page 92.
