Fujitsu PSAS CP400i SAS Controller contrôleur RAID PCI Express x8 3.0

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.

PSAS CP400i
The PSAS CP400i, eight port SAS/SATA host bus adapter provides increased connectivity and maximum performance for high-end servers and applications within internal storage. Performance is based on the LSI SAS3008 IO controller, integrating the latest enhancements in SAS and PCI Express 3.0 technology.

The PSAS CP400i provides two x4 internal SFF8643 (Mini-SAS HD), enabling a low profile solution that can achieve over 1 million IOPs. The PSAS CP400i adapter is backwards compatible with previous SAS and PCI generations through automatic negotiation and provides SAS data transfer rates of 12, 6 and 3Gb/s per lane and SATA data transfer rates of 6 and 3Gb/s per lane.

There is also an order option with separate order code for LTO which is otherwise functionaly
identical.
