LSI 25083 manual Sata II Features, PCI Express Performance, Usability Features

1.6.3SATA 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

1.6.4PCI 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

1.6.5Usability 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
