The first-to-market MegaRAID Ultra320 PCI Express RAID adapter enables a robust, effective and high-bandwidth server and storage solution. This dual-channel Ultra320 SCSI adapter in a half-size PCI form factor supports an x8 PCI Express host interface. With its superior bandwidth for component communications and a much simpler internal design, PCI Express MegaRAID storage adapters address the growing demand for higher storage device throughput and scalability requirements across midrange and enterprise class server platforms.LSI Logic MegaRAID technology continues to raise the bar by offering the highest levels of fault tolerant data protection, including Microsoft Server Clustering Support (MSCS). LSI Logics innovative intelligent Transportable Battery Backup Unit (iTBBU) technology for cached data protection allows system builders to protect cached data even during the most catastrophic system failures. Other advanced fault tolerance features - including patrol read for enhanced detection of physical device failure and temporary offline, an array recovery feature for secondary drive failures in degraded arrays - further extend MegaRAID technology as the preeminent solution for mission critical server environments.
