As far as I can ascertain the disks are "interleaved" or whatever the technical term is - i.e. the system attempts to distribute the load between the numerous swap partitions since (at least with SCSI) DMA transfers are possible leading to greater performance. The reality certainly seems to bear this out. I am, however, unable to shed any light on the algorithms used to this end. Neil.
