• Supports SMP to communicate topology management information. • Supports single PHY or wide ports consisting of 2, 3, or 4 PHYs within a single quad port. • Allows addressing of multiple SATA targets through an expander if using SATA 2.0- compliant hard disk drives. • Allows multiple initiators to address a single target (in a fail-over configuration) through an expander. Note: All expander features will not be available at launch. Online Capacity Expansion and RAID Level Migration Rules • Migration must occur to the same or larger capacity configuration. • Migration cannot occur if there is more than one virtual disk in an array. • Migration and OCE cannot be done on Spanned Arrays (RAID 10 and 50). • Migrations supported are RAID 1 to RAID 0, RAID 5 to RAID 0 • With OCE, migrations supported are RAID 0 to RAID 1, RAID 0 to RAID 5, and RAID 1 to RAID 5.
