• Each phy supports 3.0 Gbit/s and 1.5 Gbit/s SAS data transfers
• Supports SSP to enable communication with other SAS devices
• Supports SMP to communicate topology management information
• Provides a serial, point-to-point, enterprise-level storage interface
• Simplifies cabling between devices
• Provides a scalable interface that supports up to 128 devices through multiple
expanders
• Supports wide ports consisting of 2, 3, or 4 phys within a single quad port
• Supports narrow ports consisting of a single phy
• Transfers data using SCSI information units
SATA Features
The following list describes the SATA features:
• Supports SATA data transfers of 3.0 Gbits/s and 1.5 Gbits/s
• Supports STP data transfers of 3.0 Gbits/s and 1.5 Gbits/s
• Provides a serial, point-to-point storage interface
• Simplifies cabling between devices
• Eliminates the master-slave construction used in parallel ATA
• Allows addressing of multiple SATA targets through an expander if using SATA 2.0-
