Abstract
A method and apparatus for handling SGLs for out of order systems is disclosed. The method involves generating multiple Child IOs from an original IO, each Child IO being at the granularity of a storage side memory; generating separate SG lists for each Child IO; and processing each Child IO independently of other Child IOs and in order with each Child IO for data transfer. As each Child IO is generated at the granularity of the storage side memory, the Child IOs can be processed independently of each other and in-order within each Child IO. Thus, an out-of order IO transfer is transformed into an in-order IO transfer.
