> What a BS 'survey'
What is it you consider to be BS? Are you saying that the hardware numbers are wrong? An IBM z16 Max200 fully loaded has 256 cores where 200 cores are available to the customer, 40TB ram and 1,536 (4 CPC draws with 12 fanout adapters each containing 2 ports connecting to a 16 PCIe slot I/O drawer)? 32 z16 Max200 in a sysplex is 8,192 cores (6,400 customer usable cores), 1,280TB ram and 49,152 PCIe+ slots with each of the 32 boxes capable of running 1 z/OS. These numbers come from https://www.redbooks.ibm.com/redbooks/pdfs/sg248950.pdf While that is excessive, IBM can provide you with it today and you could make it run efficiently. If you were to run 1 Linux on each of these boxes, most of each machine would sit idle waiting on disk. Is it BS to say that running Linux even on a 32 core 5.5Ghx CPU is struggling to keep that box 100% busy because of disks? Is it BS to say that you won't find a motherboard with more than 8 PCIe slots or that those PCIe slots mostly go unused? Is it BS to say that any company with a 10,000 server server farm is not jumping through hoops and using an army to maintain those servers? Is it BS to say that IBM z16 failures occur on a daily basis whereas Google is constantly fixing their server farm with a large fulltime staff? I want to know why people think IBM RHEL closed source announcement is being ignored when IBM can only grow if they sell z16 to Linux only customers. Are you saying it's BS for IBM to expand into the Linux market by using existing z/OS products making RHEL compatible with z16? Is it BS for IBM to collect revenues from the z/OS products used directly in RHEL without having z/OS on any box?

CAUTION: This email originated from outside of the Texas Comptroller's email system. DO NOT click links or open attachments unless you expect them from the sender and know the content is safe. IBM RHEL announced it's move to closed source (IBM RedHat Enterprise Linux). With some changes, DB2, RACF and other z/OS products could run in Linux on z16 in one sysplexed Linux image. We know it's possible because IBM moved Unix and TCP into z/OS. IBM RHEL said closed source would force non-paying customers to buy RHEL licenses but this makes no sense. Something else must be in play. I created a survey at https://forms.gle/ZTPXsDJo8Z4H93sv7 to gain insights into IBM's decision to close source RHEL. You can skip the survey if you don't want to take it and view the survey results through this website. Feel free to pass this along. I think IBM wants to integrate z/OS products to retain their investments and expand their customer base.. Why is the z/OS community ignoring IBM RHEL closed source? Are software vendors preparing their products for Linux? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
