Intel launches Xeon 7500 server processor lineup; Promises three times increase in processing speed and 20 new reliability features http://www.cbronline.com/news/intel_launches_xeon_7500_server_processor_lineup_100331 from above: The new processor possess Machine Check Architecture (MCA) Recovery feature currently used in Itanium and RISC processors that allows the silicon to work with the operating system and virtual machine manager to recover from otherwise fatal system errors. ... snip ... note that in the 80s ... one of the reasons for various ports of UNIX (or unix-like) operating systems to mainframe continued to be run under vm370 ... was that that adding mainframe RAS was several times larger effort than the straight-forward port (instead relying on vm370 to provide the RAS, both processor and device). possibly some amount of that has since migrated to service processor ... possibly allowing such ports to be more comfortable executing in an LPAR (rather than requiring execution under z/VM). old posts about getting to play disk engineer in bldgs. 14&15 ... and doing a bullet proof I/O supervisor for them that would never fail (i.e. they had tried MVS and found MVS had 15min MTBF in their environment, once having referenced that in an internal document then brought down the wrath of MVS organization on my head) http://www.garlic.com/~lynn/subtopic.html#disk prior to the fail-proof I/O supervisor they had scheduled dedicated mainframe testing time ... typically around the clock ... a major development bottlenet. after the fail-proof I/O supervisor ... they could do any number of on-demand concurrent testing ... significantly improving productivity. -- 42yrs virtualization experience (since Jan68), online at home since Mar1970 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
