Abstract
A method and apparatus for configuring redundant array of independent disks (RAID) are disclosed. A RAID includes a processor tray having a host processor, and a drive tray having a bridge chip and multiple attachment chips. The attachment chips are connected to each other in a loop configuration. Each of the attachment chips, which is assigned with an unique node ID, is connected to a respective disk drive. The host processor can direct more than one attachment chip to participate, in various ways, to a single data transfer around the loop. This is accomplished by directing the data transfer to a specified node ID, after configuring all the other attachment chips with temporary alias node ID identical to the specified node ID to which the data transfer operation is directed.
