Raid controller system and method with ATA emulation host interface

摘要: A RAID storage device controller (70) provides a host interface (56) for interfacing the to system bus. The is isolated from attached devices, example IDE disk drives, so that actual drives are not limited in number or protocol. Various ports can be implemented, and various strategies, e.g. level 3 5, used. In all cases, standard, uniform host, namely an ATA (82, 84 86), preferably dual channel interface. emulates single one two devices per channel, regardless of physically connected controller. Thus, example, five seven deployed 5 protocol without changing standard BIOS PCI machine. Thus transparent relative board.
