The SAS/SATA technology offers a performance improvement over traditional SCSI connections. Serial Attached SCSI (SAS) and Serial ATA (SATA) are point-to-point serial peripheral interfaces in which controllers are linked directly to disk drives. This technology supports full-duplex signal transmission. SAS devices can communicate with both SAS and SATA devices. A key difference between SAS and SATA devices is, that SAS devices can have data ports, of which each resides in a different SAS domain. This enables complete failover redundancy. If one path fails, there is still communication along a separate and independent path.
The PSAS CP400e, SAS/SATA host bus adapter provides increased connectivity and maximum performance for high-end servers and applications within internal and external storage. The PSAS CP400e provides external mini SAS HD connectors and enabling a low profile solution. The PSAS CP400e adapters are backwards compatible with previous SAS and PCI generation through automatic negotiation and provide high SAS data transfer rates.
