Hipersockets may be slightly higher performance (key word:*may*) within a single CEC, but the general annoyance/complexity involved in making hipersockets work is a significant downside. Shared OSAs are far simpler to define and use, and the only limitation is how many cards you can fit into the frame. Empirical observations look like the OSAs are faster as well (and can be bridged between CECs w/o magic hardware features). ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/
