IBM doesn't require anyone to order/configure less than 200 MSUs (PCIs) of general purpose processor capacity. If you want to order a configuration like that go for it! Bearing in mind that VSEn is important and also exists, and IBM really ought to be building machines that also cater to VSEn customers, here's the current minimum orderable machine configuration (latest model) for z/OS and VSEn: * IBM z16 A02 (or AGZ for rack mount) * Capacity Model A01 * Base CP capacity: 105 PCIs (13 MSUs) * z/OS System Recovery Boosted capacity (standard/no additional charge): 1,982 PCIs * 64GB of usable memory (plus HSA) Add just 1 zIIP and you get ~1,900 PCIs of full-time zIIP capacity with 2 processor threads (SMT2). You can add as many zIIPs as you wish up to the physical capacity of the machine. Capacity Model A01 continues to be zELC eligible on the full capacity. Even though it has 105 PCIs (plus System Recovery Boost, plus more and far better on chip accelerators, plus optional zIIPs) it still qualifies for the same software licensing tier that the ~26 PCIs IBM z890 Model 110 did 19 years ago. I don't see any problem here. If 105 PCIs/13 MSUs (plus a zIIP I suggest) is all you need for your z/OS computing, well OK then! That model is available, and (in most countries) you can get a nifty rack mounted form factor if you'd like. If you need more, OK, that's available too. Here's the recent history of minimum orderable/configurable CP capacity (all Capacity Models A01): IBM z16 A02/AGZ: 105 PCIs* IBM z15 T02: 98 PCIs** IBM z14 ZR1: 88 PCIs IBM z13s: 80 PCIs IBM zBC12: 50 PCIs IBM z114: 26 PCIs * System Recovery Boost capacity: 1,982 PCIs ** System Recovery Boost capacity: 1,761 PCIs The z114 was announced in 2011 and the z16 A02/AGZ in 2023. Over that period IBM increased the minimum orderable CP capacity by ~12.4% per year (compounded), plus SRB. ————— Timothy Sipples Senior Architect Digital Assets, Industry Solutions, and Cybersecurity IBM zSystems/LinuxONE, Asia-Pacific sipp...@sg.ibm.com ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
