Exactly my thinking... We are actually getting an Altix 350 very shortly to give it a "fry" ... We shall not use SIPP only but instead use a serious of "real life" scenario tests. > > Paul's comments about the 6.4GB/s bus also intrigue me: my > understanding of the Altix platform is that this high-speed bus is > used for node-to-node interconnect, not internally within the nodes. I am not an hardware expert, but from my understanding, total numaflex bus speed is 51GBbits (ie 6GBytes ~ ) and that is what makes it capable of 5000+ calls :) _______________________________________________ Asterisk-Biz mailing list [email protected] http://lists.digium.com/mailman/listinfo/asterisk-biz
