Wasn't it called "Guaranteed-Rate I/O"?  And required the Origin ccNUMA
hardware including the HUB and XBow ASICs?  IIRC this had no real-time
guarantee, but simply reserved X amount of bandwidth from the XBow
through the HUB to the processor, and finally the kernel and process.
Whether the attached disks could sustain the reserved bandwidth was
another matter.
