max z196 config with 80 processors was rated at 50BIPS and went for $30M. Last published peak I/O benchmark was for z196 with 104 FICONs (running over 104 fibre channel) getting 2M IOPS. same z196 time-frame e5-2600v1 was 400-550BIPS (depending on model) ... about 10 times max z196. Also in same time frame, native fibre channel was announced for e5-2600 claiming over million IOPS (for single fibre channel, two such fibre channel with more thruput than 104 FICON, FICON is heavy duty prototol running over fibre channel that drastically reduces native throughput). current max configured z13 is still around $30M and 100BIPS ... compared to e5-2600v4 around 1500BIPS (1.5TIPS, more than 10 times z13, not strictly "small"). Before IBM got out of server business it had base list price for e5-2600 as $1815 (a little over $3/BIPS, compared to z13 now around $300,000/BIPS). IBM also had a high-density rack holding something like 64 blades ... would now be possibly 100,000BIPS in single rack. Large cloud operations claim they assemble their own blades for 1/3rd the price of brand named blades ... around $1/BIPS ... possibly contributing to IBM selling off its server business. typical cloud megadatacenter "server farm" will have several hundred thousand blades. recent posts mentioning e5-2600/mainframe comparisons http://www.garlic.com/~lynn/2017d.html#1 GREAT presentation on the history of the mainframe http://www.garlic.com/~lynn/2017d.html#57 What are mainframes http://www.garlic.com/~lynn/2017d.html#58 Paging subsystems in the era of bigass memory http://www.garlic.com/~lynn/2017d.html#88 Paging subsystems in the era of bigass memory http://www.garlic.com/~lynn/2017e.html#10 WD ships 'world's largest' 12TB HGST Ultrastar He12 Helium 7200 RPM Enterprise HDDs http://www.garlic.com/~lynn/2017e.html#94 Migration off Mainframe to other platform -- virtualization experience starting Jan1968, online at home since Mar1970 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
