Thank you for a detailed video. Amazing engineering. I work on distributed systems, so I do not need a massive and expensive 16 socket machine, because I can do just fine with 16 separate machines and achieve the same thing. But still, these big machines are fascinating. If you ever have time, similar presentation for z System would be appreciated.
Unfortunately I don't know anything about Z. There are some workloads that are better when not distributed. You don't state if your sockets are Power or x86? I like to think Power sockets are much more poweful! Some users use large Power servers to run 100's to 1000's of VMs on a single box. So they may be apparently expensive but we have competitive bangs per buck. Fewer larger servers are easier to manage and the peaks average out to give higher efficiency.
Hi, You seem to be confusing a multi-million dollar machine with up to 240 CPUs and 64TB of memory and run the largest RDBMS in the world and/or 100's of virtual machines with a PC.
Nigel, I bet you heard of Raptor Computer's Talos Power 9. Does IBM have something similar for Power 10, just selling a mainboard and CPU? What would you recommend for a 5 man game company that just needs a stand alone server for builds and handling some email? With Linux or FreeBSD on it. Those customers who would just buy an AMD Epyc, does IBM have anything for small enterprises? Raptor won't make a Power 10 product because lack of open source firmware, and tbh Power 9 is getting long in the tooth All I could find from IBM so far is the E1080 for whales who don't mind pricetags ending on "million"... but I was wondering if IBM intends to service the dolphin market too
Only the top end of Power10 has been released. In 2022 the Midrange and Scaleout planned = follow on for POWER9 E950 and S922/S924 with more than double the CPU Cores. Guessing that the Open Power10 third party severs will arrive at that time. I cant say more as they are not announced and I like my job. 😃
I am really surprised that the VRMs are so far from the CPUs. At 1V there is going to be substantial voltage drop, unless the copper traces and cables are really really thick. I wonder why VRMs where not put close to CPUs on another side of the chassis. But I guess, the VRMs do have a sense lines back from CPU back to VRM, so they can compensate for the voltage drop. Also it is a little bit weird that SCU uses power from CEC, instead of having own power redundant supplies. It does not require a lot of power I guess, but it is weird it is stealing power from other system, instead of using own.
Yes lots of copper. On the SCU with quadruple power supplies a short cable away why add more parts to fail and you are right the SCU does not demand much electricity.
thanks Nigel,truly you are the god of IBM power systems.

Would be great if there was an alternative for an ATX form factor.

Still would want some form of this machine in an ATX form factor as a workstation. @@nigelargriffiths

@@nigelargriffiths Thank you so much, looking forward to 2022 then. Please keep your job, you're doing it very well.
This is so cool
