LSI Logic megaraid sas 9341-8i sgl [11/45] The following list describes the pcie performance features of the raid controllers

Sas controllers leverage a common electrical and physical connection interface that is compatible with serial ata technology the sas protocols and the sata iii protocols use a thin 7 wire connector instead of the 68 wire scsi cable or 26 wire ata cable the sas sata iii connector and cable are easier to manipulate allow connections to smaller devices and do not inhibit airflow the point to point sata iii architecture eliminates inherent difficulties created by the legacy ata master slave architecture while maintaining compatibility with existing ata firmware 8

Sas is a serial point to point enterprise level device interface that leverages the proven scsi protocol set sas is a convergence of the advantages of sata scsi and fibre channel and it is the future mainstay of the enterprise and high end workstation storage markets sas offers a higher bandwidth per pin than parallel scsi and it improves signal and data integrity 8

The following figure shows an example of a sas raid controller configured with an lsisasx12 expander that is connected to sas drives sata iii drives or both 8

The sas interface uses the proven scsi command set to ensure reliable data transfers while providing the connectivity and flexibility of point to point serial data transfers the serial transmission of scsi commands eliminates clock skew challenges the sas interface provides improved performance simplified cabling smaller connectors lower pin count and lower power requirements when compared to parallel scsi 8
