there are a couple of such discussions in linkedin mainframe oriented groups (both ibm employees and customers). 1qtr2014 IBM financials has the equivalent of 17-18 max-configured ec12 (latest ibm mainframe) being sold (56 on annualized basis) @33M which is rated at 75BIPS ... or about $440K/BIPS ... is built out of 32nm technology, six processors in 597mm chip. a typical cloud megadatacenter has more processing power than the aggregate of all mainframes in the world today ... a typical component is e5-2600v1 blade which they build for possibly $1/BIPS. currently selling are e5-2600v2 and coming on line this year are e5-2600v3 blades using 14nm technology ... intel has spent $5B on 14nm technology fab and will feature move from 300mm wafers to 450mm wafers if the ec12 chip was simply remapped from 32nm to 14nm 450mm wafer ... a total full years sale of ec12 then is single wafer. ibm mainframe CKD DASD haven't been manufactured for decades ... being simulated on industry standard fixed-block disk ... because their mainstream mainframe operating system doesn't have support for fixed-block disks. ibm mainframe i/o "channels" are called "FICON", a heavyweight protocol layer that runs on industry standard fibre-channel (and drastically reduces native throughput). A mainframe max I/O benchmark published for z196 (precursor to ec12) used 104 FICON to get 2M IOPS ... about the same time a single fibre-channel was announced for e5-2600 claiming over 1M IOPS (two such "native" fibre-channel having higher throughput than 104 FICON). again for z196 (i don't think they have published for ec12 yet), peak i/o SSCH operations is 2.2M/sec with all i/o system assist processors running at 100% busy ... however, they recommend not running the mainframe SAPs more than 75% busy or 1.5M SSCH/sec. the published numbers for ec12 claim only 30% increase in I/O over z196 (possibly because of combination of FICON and SAP limitations). max configured z196 was 80 processors for 50BIPS (625MIPS/processor) while ec12 is 101 processors for 75BIPS (743MIPS/processor) posts mentioning FICON http://www.garlic.com/~lynn/submisc.html#ficon recent posts mentioning ec12 &/or z196 http://www.garlic.com/~lynn/2014f.html#49 Beyond the EC12 http://www.garlic.com/~lynn/2014f.html#50 Beyond the EC12 http://www.garlic.com/~lynn/2014f.html#51 Beyond the EC12 http://www.garlic.com/~lynn/2014f.html#53 IBM hopes new chip can turn the tables on Intel http://www.garlic.com/~lynn/2014f.html#65 non-IBM: SONY new tape storage - 185 Terabytes on a tape http://www.garlic.com/~lynn/2014f.html#67 Is end of mainframe near ? http://www.garlic.com/~lynn/2014f.html#69 Is end of mainframe near ? http://www.garlic.com/~lynn/2014f.html#72 Mainframe (in general) running at 100% not always a bad thing http://www.garlic.com/~lynn/2014f.html#73 Is end of mainframe near ? http://www.garlic.com/~lynn/2014f.html#75 Is end of mainframe near ? http://www.garlic.com/~lynn/2014f.html#78 Over in the Mainframe Experts Network LinkedIn group http://www.garlic.com/~lynn/2014f.html#80 IBM Sales Fall Again, Pressuring Rometty's Profit Goal http://www.garlic.com/~lynn/2014f.html#86 Is end of mainframe near ? http://www.garlic.com/~lynn/2014f.html#92 Is end of mainframe near ? http://www.garlic.com/~lynn/2014g.html#2 Is end of mainframe near ? http://www.garlic.com/~lynn/2014g.html#4 Is end of mainframe near ? http://www.garlic.com/~lynn/2014g.html#12 Is end of mainframe near ? http://www.garlic.com/~lynn/2014g.html#14 Is end of mainframe near ? http://www.garlic.com/~lynn/2014g.html#20 Is end of mainframe near ? http://www.garlic.com/~lynn/2014g.html#49 Is end of mainframe near ? http://www.garlic.com/~lynn/2014g.html#105 Fifty Years of nitpicking definitions, was BASIC,theProgrammingLanguageT http://www.garlic.com/~lynn/2014h.html#2 Demonstrating Moore's law http://www.garlic.com/~lynn/2014h.html#4 Demonstrating Moore's law http://www.garlic.com/~lynn/2014h.html#5 Demonstrating Moore's law http://www.garlic.com/~lynn/2014h.html#7 Demonstrating Moore's law http://www.garlic.com/~lynn/2014h.html#8 Demonstrating Moore's law http://www.garlic.com/~lynn/2014h.html#9 Demonstrating Moore's law http://www.garlic.com/~lynn/2014h.html#11 Demonstrating Moore's law http://www.garlic.com/~lynn/2014h.html#41 The Tragedy of Rapid Evolution? -- virtualization experience starting Jan1968, online at home since Mar1970
