That peak I/O benchmark used 104 FICONS (to achieve 2M IOPS). ... I've mentioned before about the same time there was a FCS announced for e5-2600 claiming over million IOPS (for single FCS) ... aka my theme that FICON is a heavy duty protocol layer on top of FCS that drastically cuts the native FCS throughput ... some past posts http://www.garlic.com/~lynn/submisc.html#ficon -- 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
