Talk about one of the big machine series
Home from work, a cup of strong tea and a computer. Toad also came to talk about big machines.
Since June 5, 2013, when the Guardian of Britain first threw out the first bomb of prism, IOE has become increasingly fierce in China. So the question is, can’t a big function be replaced? When will it be replaced? How long can ORACLE and EMC continue to have their way in China?
Oddly enough, alibaba removed its last IBM machine from Alipay in May 2013, and the Guardian reported the Prism scandal on June 5, 2013. Could Ali have planned this? I have to give boss Ma a thumbs up. Alibaba replaced IBM’s small machines with X86 servers, ORACLE databases with open source databases, and EMC with low-end storage. It took a lot of work, and it must have been planned for years, and it’s not just about security. One of the reasons was that in 2008 alibaba’s database was unimaginably large and ORACLE couldn’t produce reports. Coupled with the KIDNAPPING of IBM sales students in suits, Boss Ma had had enough.
Let’s go back to the text. Ali replaced a small machine instead of a big one, so is it a big one?

What is a big machine?
Mainframe, or mainframe, in English. Mainframes use a dedicated processor instruction set, operating system, and application software.
In April 7, 1964, the birth of the first IBM mainframe (SYSTEM/360), the product toad can only say: rich is capricious. At that time, IBM hired 60,000 people, built 5 or 6 factories and felt like the company was going to go out of business, but they made products. Applause. At that time, the chief engineer in charge of software later wrote a book called “The Myth of the Month of Man”.
The SYSTEM/360 is rated as one of three commercial achievements in history alongside the Model T Ford and Boeing’s first jet, the 707. This product not only changed the entire computer industry, but also CHANGED IBM. So at the thought of someone wanting to replace the big machine, Toad began to ho-ho, ok? Then there’s the leader’s slap
Let’s take picture 1
The latest IBM mainframe is the Z series, and the most recently released Z series is the Z13. The Z13 system can support up to 10 TERabytes of memory (although it doesn’t feel too huge, X86 servers can run 12 TERabytes of memory with 8 channels on the IVB platform). Of course we can’t look at the supported memory size, otherwise the world wouldn’t be so simple and boring. It depends on the architecture. It depends on the reliability.
Big machine, small machine, X86 server difference
size
Big machine small machine difference is actually very simple, look at volume bai. That’s how they got their name
Generally it is large machine size > small machine size >X86 server, of course this is the theory. Now, getting a 64 on an X86 server isn’t necessarily smaller than a small machine or something.
hardware
That’s actually one of the keys.
Large machine chips, small machine chips, and X86 server chips are all different.
Small computers are P-series (Power CPUS), while X86 servers are INTEL cpus. This leads to architectural differences.
But what Does Toad think of the X86 server is the enhanced version of the home computer, since INTEL started making small chips. When the home PC came out, IBM said, “If I go, can the player also be a computer?” Now think can only ha ha
application
Of course, the above running system is still different, IBM mainframe can run the system z/OS, Z /VM, Linux onSystem Z and so on,
IBM computers run UNIX systems like AIX.
X86 servers run RedHat, SUSE, Windows, etc.
What do you want now?
Right now, I’m just trying to replace you. So here comes the IBM guy in suit and tie, and it’s not likely to be replaced anytime soon, because… (10,000 words omitted here).
But to be honest, if replacing the big machine is because of price, because of the architecture, because of the application toad can totally understand, if replacing the big machine is just because of the prism security problem, then the problem is? What do we replace the big machines with, X86 machines?
Ha ha, X86 chip is not our own homemade, a few years out of a brick they are not to replace?
But aside from CPU, memory, and hard disk, the rest of the X86 servers are pretty much homegrown. Haha, I don’t understand ~
Next time we will talk about the replacement of the big machine
