NM: Fibre Channel RAID controllers are the heart of SANs, we term our RAID controllers when used in a SAN as SAN Storage Controllers (SSCs).
If the purpose of RAID is fault tolerance, certainly optical has greater benefits," O'Neil said.
is a leader of Ultra DMA/ATA and Serial ATA RAID Controllers for data storage within the PC industry.
Fibre Channel is slowly taking a larger share of the high-end market from SCSI, while less complex and less expensive host-based RAID systems are becoming increasingly attractive to low-end and mid-range users.
Therefore, for a workstation, a very appropriate architecture is to implement your RAID using the host CPU.
If one of the three drives is actually removed, a RAID controller recreates the missing data in realtime, based on the bits of data remaining on the other two drives.
A description of RAID 6 that may soon enjoy wide acceptance was launched in 1997 based on Reed-Solomon coding.
Original RAID specifications defined five levels of various disk array architecture protection schemes--RAID 1-5.
These new RAID controllers leverage the power of ATTO's customer-proven high-performance RAID technology - including the company's proprietary Advanced Data Streaming (ADS[TM]) Technology that alleviates data transfer bottlenecks - and the new 800MHz PCIe Intel([R]) IOP348 I/O Processors with integrated high-performance XScale([R]) technology to meet the most demanding performance requirements of data-intensive applications, including transactional databases, email servers, large server farms and digital media.
The shift from parallel technology to the emergence of new serial based architectures as new I/O standards for direct attached storage changes the traditional cost/benefit equation, and the addition of powerful, yet cost-effective RAID capabilities alters the landscape for low-cost server storage.
Applied Micro Circuits Corporation (AMCC) (NASDAQ-GS:AMCC) today announced its high performance 3ware[R] 9650SE SATA II RAID controller family, featuring RAID 6 with simultaneous double-parity generation for significantly improved fault tolerance.
