The processors network with each other, | notice when they're not using all of their caches, and shares | that cache with things far away (ie: in side the box, or even | outside the box). | | This way, IBM can overprovision L2 cache and "not worry" about | it going unused. Remote L2 cache is slower than local L2 cache, | but its still SRAM and should still be faster than DRAM to | access. | Andys wrote: | When it must be so expensive its not even "call us", but | "Schedule a Consultation". | | You fit in with their schedule, not the other way around? | nix23 wrote: | Pff it's IBM you buy the Consultant with it, he sits in the | lower rack and has spacefood rations for 5 years, then you have | to do maintenance and the consultant get exchanged and retired. | | But!! No shutdown needed. | Our_Benefactors wrote: | Can they be put on a generator bike? I'm concerned about | their carbon footprint. | broodbucket wrote: | Nonsense, there would be at least one more redundant | consultant if not two. | | Seriously though, these machines call home when there's a | hardware failure, they'll fail over and someone will show up | to replace what failed. Enterprise tech is sometimes cool. | xhkkffbf wrote: | This is pretty standard across much of the enterprise world. | The sales team just has to earn their commission. | | Indeed, even when they have publicly listed prices, it's | usually possible to negotiate a substantial discount by dealing | directly with the sales team. Like 50% is often possible. | Andys wrote: | Yeah, I know. Just poking fun of their level of hype being | such that they make it sound like you are one of a privileged | few if they even take your call and allow you to buy this | apparent masterpiece. | broodbucket wrote: | The general rule of thumb is if the product page says | "contact us" instead of a price, you can't afford it. | | It is a shame though. IBM has no idea how to sell to anyone | other that gigantic megacorps - which, fair enough, but | they could probably pick up a lot of sales to medium-sized | businesses if they weren't so old-fashioned about | everything | wmf wrote: | If you buy an IBM mainframe you'll have a very attentive full- | time account manager for life. I did a ride-along with such an | account manager once when I was working at IBM and it was eye- | opening. | miohtama wrote: | What is the Linux distro powering this beast? | wmf wrote: | RHEL, SLES, or Ubuntu. | treis wrote: | This is the fine print: | | >Compared 5 IBM Machine Type 3931 Max 125 model consists of three | CPC drawers containing 125 configurable cores (CPs, zIIPs, or | IFLs) and two I/O drawers to support both network and external | storage versus 192 x86 systems with a total of 10364 cores. IBM | Machine Type 3931 power consumption was based on inputs to the | IBM Machine Type 3931 IBM Power Estimation Tool for a memo | configuration. x86 power consumption was based on March 2022 IDC | QPI power values for 7 Cascade Lake and 5 Ice Lake server models, | with 32 to 112 cores per server. All compared x86 servers were 2 | or 4 socket servers. IBM Z and x86 are running 24x7x365 with | production and non-production workloads. Savings assumes a Power | Usage Effectiveness (PUE) ratio of 1.57 to calculate additional | power for data center cooling. PUE is based on Uptime Institute | 2021 Global Data Center Survey | (https://uptimeinstitute.com/about-ui/press- | releases/uptime-i...). CO2e and other equivalencies that are | based on the EPA GHG calculator | (https://www.epa.gov/energy/greenhouse-gas-equivalencies-calc...) | use U.S. National weighted averages. Results may vary based on | client-specific usage and location. | nisa wrote: | Wondering how a dual socket AMD EPYC(tm) 9654 system with 2x96 | cores would compare. It's not clear how many 14nm+ Cascade Lake | machines were used and it's also not clear how many 32core | machines were used. 10364cores/192servers averages about 53 | cores/server. | | It's apple and oranges anyway because I guess if you consider | this you have different priorities but I'm skeptical that x86 | couldn't come close in terms of performance/watt ___________________________________________________________________ (page generated 2022-11-14 23:00 UTC)
