See also the tested hardware and operating system list for the RAID Controller SRCSASPH16I to make sure the RAID card supports your operating system. Beep Codes • Short beep, 1 second on, 1 second off: The array is degraded, but no data is lost • Long beep, 3 seconds on, 1 second off: The array has failed and data has been lost. • Short beep, 1 second on, 3 seconds off: Using hot spare in rebuild. The alarm will continue during the rebuild with a different sound at completion. To disable the alarm, choose Disable Alarm. To disable the alarm only until the next event or until the next power cycle, choose Silence Alarm. To enable the alarm, choose Enable Alarm. Benefits of Serial Attached SCSI (SAS) 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 FC, and is the future mainstay of the enterprise and high-end workstation storage markets. SAS offers a higher bandwidth per pin than parallel SCSI, and improves signal and data integrity. 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. SAS controllers leverage a common electrical and physical connection interface that is compatible with Serial ATA technology. The SAS and SATA protocols use a thin, 7-wire connector instead of the 68-wire SCSI cable or 40-wire ATA cable. The SAS/SATA connector and cable are easier to manipulate, allow connections to smaller devices, and do 5 Intel® RAID Controller SRCSASPH16I Hardware Guide
