Overview
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 up to 12Gb/s.¦SAS devices can communicate with both SAS and SATA devices. A key difference between SAS and SATA devices is, that SAS devices can have two 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 CP500e, eight port SAS/SATA host bus adapter provides increased connectivity and maximum performance for high-end servers and applications within internal and external storage. Performance is based on the Broadcom SAS3408 IO controller, integrating the latest enhancements in SAS and PCI Express 3.1 technology. The PSAS CP500e provides two x4 external miniSAS HD connectors (SFF-8644) and enabling a low profile solution that can achieve over 1 million IOPs.
