• 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
1.6.3 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
• Provides unequaled performance through the Fusion-MPT
architecture
• Provides high throughput and low CPU utilization to offload the host
processor
1.6.4 Usability Features
The following list describes the usability features of the RAID controllers:
• Simplifies cabling with point-to-point, serial architecture
• Supports smaller, thinner cables that do not restrict airflow
• Provides drive spin-up sequencing control
• Provides one LED signal for each PHY to indicate link activity (this
is a fault LED only for controllers with internal port connectors)
Note:
The SAS 9280-8e RAID controller and the SAS 9280DE-8e
RAID controller do not have any LEDs to indicate link
activity.
• Provides an I
