The RAID concept (Redundant Array of Independent Disks) refers to several independent hard disks which form a large logical drive when switched together. Redundancy information is calculated from several data blocks (except for RAID 0) and saved distributed to the individual hard disks. Your operating system no longer accesses the individual hard disks, but the array. The actual objective of the RAID concept is to increase availability and prevent downtimes in the event of a hard disk failure. However, the theoretical security of the RAID concept is only as good as the RAID controller used. Benefit from the Fujitsu RAID controllers where technology, experience and practical implementation all ensure the security that your company needs in the event of an emergency. The 8 port Fujitsu D2616 SAS/SATA RAID controller sets new standards in the fields of speed and data security for internal server memories. With a data transfer of up to 6Gb/s per port the PRIMEGY Modular RAID Controller family is extended to included the latest technology. The RAID stack is based on the LSI MegaRAID and offers high data throughput, a comprehensive error tolerance function and user-friendly management options. Management of the controller is integrated seamlessly into the FTS management concept. All controller functions are supported by the FTS ServerView RAID Manager. 6Gb/s SAS is designed for backward compatibility with 3Gb/s SAS as well as with 6Gb/s and 3Gb/s SATA hard drives. Regardless of the drive speed, 6Gb/s MegaRAID controllers will deliver significant performance improvements in both read and write applications, as compared with their 3Gb/s predecessors. Other new features of the 6Gb/s SAS 2.0 controllers include greater signal integrity using Decision Feedback Equalization, support for more sophisticated SAS topologies using Expander Self-Discovery / Self-Configuration, and additional safeguards to enhance data protection. Due to the support of 64-bit addressing, a robust set of RAID features and demanding error tolerance functions this controller provides high RAID performance and data availability. Powerful online management service programs (FTS's ServerView RAID Manager), which are simple to operate and quick to install, provide the administrator with unparalleled flexibility and access to the arrays. The RAID controller supports all of the important RAID levels including RAID 6 and 60. RAID 6 tolerates up to two simultaneous drive failures and thus also the option of managing non-recoverable media errors during rebuilds. This is especially advantageous if a large number of high-capacity.
