1.6.3 SATA II Features
The following list describes the SATA II features of the RAID controllers:
•Supports SATA II data transfers of 3Gb/s
•Supports STP data transfers of 3Gb/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 II targets through an expander
•Allows multiple initiators to address a single target (in a fail-over
configuration) through an expander
1.6.4 PCI Express Performance
The following list describes the PCI Express performance features of the
RAID controllers:
•Provides a PCI Express interface that:
– Supports a dedicated PCI Express bus
– Supports x8 lane configuration
– Supports transfer rates of up to 5Gb/s per lane
– Complies with the PCI Express Specification, Revision 2.0
