RAID Subsystems with Host Interface PCI Express

External PCIe Attached Raid subsystem takes high performance advantage of PCI Express link with 1000MB/s data throughput (250MB/s per lane & 4 lane simultaneously) connecting simply between memory and Raid set via DMA (Direct Memory Access) schema to reduce CPU resource overhead. A new polynomial RAID 6 tolerates two disk fail at the same time enhancing Data reliability. Combining Raid subsystem and PCI Express card solves compatible issue on cross-platform with various drivers support and breaks limitation of narrow space in server machine by up to 128 HDDs capacity with SAS JBOD scalability, which is suitable and cost-effective solution for such as content creation, multi-stream video editing, multi-media on demand, all required high performance, scalability and data reliability applications

DSCon offers AXUS RAID subsystems with host interface PCI Express using SAS and SATA drives.
