I know about ECC; are there any larger systems that use just parity, but attempt to handle it more reasonably? How do larger systems handle ECC correction failures? Well, on Sun 3/50s, it panics and reboots. Hardly a _large_ system, but get much larger and they tend to have ECC. Suns with ECC print a diag when correcting; I have never seen an uncorrectable error. -- Gregory Bond, Burdett Buckeridge & Young Ltd, Melbourne, Australia Internet: gnb@melba.bby.oz.au non-MX: gnb%melba.bby.oz@uunet.uu.net Uucp: {uunet,pyramid,ubc-cs,ukc,mcvax,prlb2,nttlab...}!munnari!melba.bby.oz!gnb
