Multicasting exists for control operations (everybody wake up) but not transfers.
HA! So, little has changed since the PDP-11 days. The disk controllers then could manage 8 'spindles', that is do seeks on all 8 simultaneously ready for a transfer, but only had one transfer channel. You could, and I did, write a striping controller that put a 4K logical file block on each of 8 512 byte sectors but the reality was that it was slower than streaming a 4K clock onto a single platter. -- /"\ \ / ASCII Ribbon Campaign X Against HTML Mail / \ -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
