Yours for only $135k (starting)! Supposedly it's designed for eight nines (99.999999%, or ~30 seconds of downtime a year) and a MTBF in the decades. I'm curious if at that point, assuming it lives up to it, if other factors outside of it, like DC power and cooling availability or internet connectivity, won't also be difficult to achieve.
- neverartful 3y agoThe $135k is just the hardware price for the base configuration. I'm sure you're required to license several software SKUs that are not cheap and that you have to pay annually for maintenance.
- rbanffy 3y agoI don't think that's true for LinuxONE. One of the points is that it behaves as a large and fast (with lots of dedicated acceleration hardware) Linux machine.
- neverartful 3y agoReally? No license for PR/SM, z/VM, etc.?
- benjarrell 3y agoYou also need an IBM storage array
- wmf 3y agoI don't think LinuxONE requires that.
- neverartful 3y agoYou probably do need a storage array, but I doubt it has to be from IBM. Ever hear of EMC?
- tyingq 3y agoTrue. Here's the footnote on that $135k: "5 This price reflects the base hardware configuration, and does not include additional items, maintenance, the operating system or other software. All prices are in USD. Prices shown do not include tax. Price will vary based on country and currency." https://newsroom.ibm.com/2024-02-06-New-IBM-LinuxONE-4-Express-to-Offer-Cost-Savings-and-Client-Value-through-a-Cyber-Resilient-Hybrid-Cloud-and-AI-Platform https://newsroom.ibm.com/2024-02-06-New-IBM-LinuxONE-4-Expre...
- Yasuraka 3y ago30s a year is 6 nines, 8 would be 300ms
- gottorf 3y agoI believe the ninety-nine before the decimal point counts as two of the nines, but I'm sure different people word that differently.
- jhallenworld 3y agoor, especially, software It's a z-series mainframe and I don't doubt these reliability numbers. The world's financial system runs on these mainframes. An undetected bit error at the federal reserve might cause IBM to appear in the news, in a bad way, like Boeing.. It will not have the fastest single-threaded performance, but that's not why you buy it. The mainframe mindset: Of course each core is running at 100% all the time... I paid a lot for it, so I want my money's worth. z/OS is designed to make this feasible. Not sure how well that works in Linux.. but it's where the market is.
- bitwize 3y agoThe LinuxONE line is, I believe, a series of Linux-only mainframes; z/OS is not an option on them. They're IBM's entry-level option for businesses who salivate at those mainframe reliability numbers but don't have any OS/360|OS/370|z/OS apps and don't want to pay for the support on those systems.
- jhallenworld 3y agoI think you're right it can't run the apps, but I see it's running z/VM as the hypervisor.
- bitcharmer 3y ago> The world's financial system runs on these mainframes No, it hasn't for a long time
- dalemhurley 3y agoSo one month of AWS costs.
- hobobaggins 3y agoYou made me spit my Java out. (and you're right, even for smaller companies)
- wmf 3y agoA single box of any type absolutely cannot deliver eight nines. Maybe a sysplex running very limited software...
- neverartful 3y agoI would suspect that it IS multiple boxes and with z/VM using single system image. This is the first time I've ever heard of mainframe "in a rack". In the past they come in their own cabinet, but if you open the cabinet door you won't see one "box".
- wmf 3y agoNo, it's a single box with one Telum chip.
- neverartful 3y agoOk, good to know!
- hobobaggins 3y agoTell that to my Linux boxes that have been up for years, or others who have been up for decades.
- e12e 3y agoI mean it's susceptible to fire an ac/cooling failure - other than that? Redundant power, redundant connectivity are both feasible?
- billforsternz 3y ago30,000,000 (ish) seconds in a year, 99.999999% of that is .... let me see, 99.999999% of 100,000,000 is 99,999,999 I suppose. So downtime is what's left over, about 1 second every 3 years or 300 milliseconds a year not 30s a year. I think.
- kens 3y agoNo, eight nines is 316 milliseconds of downtime per year. 30 seconds of downtime a year is six nines. (I spent a long time working on high availability at Sun, so the numbers immediately looked wrong.) https://en.wikipedia.org/wiki/High_availability#Percentage_calculation https://en.wikipedia.org/wiki/High_availability#Percentage_c...
