Powering up the IBM Z890 mainframe and teardown - (PWJ148)
HTML-код
- Опубликовано: 9 июл 2019
- We were cleaning up our stock. Some older systems have to go because they became obsolete. Here is a view of the IBM Z890 mainframe system. It is (more or less) complete and working. A pity to throw it away but we need space now.
The best I could do was playing with that soon to be junk....

Built like a tank, weight of a car, sounds like a plane and performance of a raspberry pi 4 - I LOVE IT :-)
Take a look at my icon/avatar. IBM 360/44 in 1967 - Built like a tank, weight of a car, sounds like a plane and performance of a modern watch (probably less). But we were doing particle physics research. I LOVED IT.
TheTaleteller quite a bit faster and more capable than a raspberry pi
@@latentexistence A raspberry pi also does not have the virtualization capability to run multiple VMs with little slow down.
The IBM Z line which is still produced are able to replace an entire room of PC servers.
I was really wondering how it compares to present day computer. hahahahahaha, rasberry Pi level at 700KG
@@renderdreality well if it is how it was then my pc would destroy it but if that thing was fully connected to everything my pc would not stand a chance im pretty sure i dont know much about servers (my pc specs intel core i5 7400 3.00ghz 4 core 8gb xfx radeon r9 390 16gb ram 2133mhz if i had correct board 3000mhz) i kinda wonder if it would stand to that server if that server could run windows
This is the last IBM iron I used before retiring in 2008 . It was really good stuff , I worked at my alma matter University of Calgary in western Canada. We could register 35000 students for classes , process payroll for 20,000
Full and or part time staff all using COBOL green screens and finally full GUI IP connected web apps running on this box under IBM Websphere and MQSeries messaging services tied into IMS Databases and CICS online transaction processing monitor doing in excess of one million online real-time transactions per day , that was a very small shop. Some IBM environments ran in excess of 20,000,000 transactions per day like banks and airlines that still use the big iron. Glad to see this hardware is surviving for future generations to see trust me it’s successors will be around for a long time yet !
Looks like a very efficient way of turning electricity into noise and heat :) Love it!
🤝 The best comment!
In fact, a computer produces absolutely nothing except heat. Even the sound that is kept in a closed room will heat up the air.
100% efficient
There was nothing more satisfying than upgrading your RAM and booting for the first time, watching the memory check go beyond its previous limit...
1k... 2k... 3k... 4k... I wonder how long it takes if you upgrade such an old PC to 4 Jiggabytes
@@PlaywithJunk Well I remember upgrading countless PC's and XT's, and I can tell you... forever lol. Thank doG for the quick boot option on later BIOSes and automatic configuration (no mobo switches!)
@@Masp89 good lord... I worked for IBM for a minute... that's right.. .it's an IPL
So you're saying that having sex wasn't as satisfying as upgrading your RAM? 🤔🤭
@@shinigamilee5915it depends how much RAM is being added really
This machine debuted at $200,000 usd in 2004.
It has one processor book of four processing units, compared to the z990 that had four books of eight!
This unit was primarily made to bring in customers who didn't need the large, gaudy power of the larger systems.
But also to bring in customers who were simply using the older mainframe series.
Only 200k?
with only 1 pu book i would guess 800-900.000 usd new
and you could upgrade to the zAAP processor for only $125,000 each.
I remember when we were replacing our ES9000s with these. Now I feel old.
Yes! Very old indeed. We replaced an aging Cray that took up a whole building with a SGI Challenge that had 1Gb of ram, and was about the size of a refrigerator.
I like how you bothered to set the correct time and date when it's just going to be scrapped.
Yeah :-) The problem is that when you don't fix the date and time, it will probably not start up correctly. And I wanted to show how it starts. I even tried to fix the power supply but was not successful.
you didnt scrap the service elements did you? A shame to see vintage hardware die
Hey, I'm that guy you mentioned in the video!
I will say some of your earlier videos of tearing down a z9 I believe it was, was part of my inspiration to hunt out a mainframe!
So its funny to come full circle here hah.
Also yes, you pronounced my last name just fine, though I don't think my family ever really had a super proper pronunciation :)
Also ESCON is similar to FICON just older. Its our connection to storage and other devices.
Way back on the S/360 and S/370 we had bus and tag. I believe we introduced ESCON, as the first fiberoptic interconnect for mainframes in the S/390 era.
Then FICON came along in either late S/390 or early zArch like the z800 or similar.
Which FICON is a derivative of the Fiber Channel protocol and actually all our FICON cards support Fiber Channel.
Its great to have your videography skills go over this machine. I took some photos and did some bad videos of mine way back I think but ultimately my talk is what got out.
Glad you were able to go through a machine and really show people what I was unable to show in my talk.
Post some more stuff you’re messing with! I’m fascinated by this aircraft carrier sized gear, and have super envy of you guys. And zero use case for the machine, but, hey it’s fun, right?
Hi there, nice to read you :-)
It's fascinating, when I google "Z890" the first dozen of results is about you and your andveture of buying a mainframe. I can fully understand why you did that. When I was a child, I saw an ad in the local newspaper. It said that a "NCR Mainframe System" (don't ask me what type) was given away for free.
I called the company and luckily the guy there realized that I was only a child with no idea what to expect. I thought I could store it in the basement for a while.... downstairs! I'm happy that I didn't got it. I think my parents would have freaked out :-)
I have also seen you presentation at the hackers convention (?). While the story alone is interesting, your kind of presentation was also quite entertaining... well done.
So I hope you still have fun with your Z890. I personally wouldn't know what to do with it... It would be interesting to know how it compares to a modern desktop computer in terms of speed, benchmarks. Have you done something like that?
Sure it's fun. This is stuff you're normally not allowed to touch...
First I thought the one in the lambo :D
I watched your presentation video about this mainframe, very entertaining. It's interesting how quickly the latest top of the range tech soon becomes obsolete junk that is difficult to give away ...👍😎
Having said that I still work on an old P4 PC that runs windows XP, the software I use only works on that OS, it all works fine and does everything I need. I now have picked up 3 other old P4 PCs for spare parts, for free lol 😁
I do enjoy firing up an old machine and find it fascinating when they start up fine with no errors! A bit like starting up an old car in the first turn of the key 😎👍
I've also picked up some old pocket PC computers, a bit like calculator sized devices, with a one line dot matrix LCD display, they used to sell very cheaply on Ebay, they used to be £100s when new, bought it just to use as a retro calculator, not sure why, when I have a samsung galaxy s9 smartphone that does pretty much all my computing needs🤔😁
I just recently stumbled upon your channel and your videos like this one are EXACTLY what I've been looking for. I absolutely love messing around with old high end Enterprise equipment but I've never personally been able to find something quite as monstrous as this thing :)
Thank you.... you're welcome!
Jesus that thing was like a jet engine taking off, amazing!!!
Would be a dream to be able to play around with such a machine! I've salvaged a lot of old servers a company was going to throw away but never such an amazing machine...
You would need a LOT more supporting hardware to get anything done. There is no disks attached hence no O/S
Just love the noise from these machines. It feels like real power when you have no recognition of noise just simply the best cooling you can get. What a monster, I'd love one just for the noise😀 thanks for showing us this.
OS/2 was used in most ATMs until very recently, there would presumably have been backend OS/2 Warp servers, though most probably interfaced with legacy servers going back decades for well established banks
I went to get cash at one ~20 years ago and it rebooted, showing an OS/2 Warp logo, then a desktop. The touch screen did nothing, so no cash and no ability to play.
@Michael Hansen Sorry, you are wrong. I worked at a major UK bank in the late 90s and it was used directly on ATMs
Interesting machine, but what's even more interesting these are a source for nearly new condition retro Thinkpads :)
Those fans almost sounded like jet engines spooling up..Can almost imagine a cockpit conversation...”Thrust set..checked....V1...Rotate..Positive climb...” And there you have it..an up and running system
yes. a kind of increasing noise level "mainframe ready for take-off"
Mother of mercy, does this thing comes with a portable fusion reactor in an extra trailer?
Man... I've setup so many of this :) that's not noise, 20 nodes of that is noise :D and a small nuclear power plant to feed them, those things eat electron for breakfast, at full load, 100Kw to 150Kw. Amazing machines from another era. Still have a few parts of them hanging on the garage. I just wonder they worked so many time in your shop, they are complete daisys with temperature. Nice to see on outside a DC.
Does this need three phase power supply?
ah memories of installing warp (20 floppies) over win 3.1 and seeing that slicker looking gui for the first time.
Or seeing FreeBSD install in 4 minutes compared to Windows 40 minutes.
Hehe, the power-connectors make me remember the huge UPS rackmount case we took over from a bankrupt school. When it was inside and colleagues were thinking about installing the batterypacks (huge 18 kilo rackmount batteries from which we had 10, I think), when it was on the second floor (a wooden one) someone asked what the maximum weight allowed on the second floor was.
It was somewhere around 330 kg's per square meter or something (which is probably a value with some kind of margin, but still), and should they have installed every battery and the three inverters (25 kilo's each) they would've exceeded the maximum amount of weight by about 300 kilo's.
They quickly decided to spread the weight as much as possible by taking out all the batteries and inverters and storing them as spreaded as possible.
When we had to dispose of it (2 times 3 phase power was not available in our building and remodelling was far away at that moment and it was taking up way to much space) the building outside of our room had been remodelled and they had put wooden flooring in, that heightened the floor just enough to be unable to get it out of our room, and (especially) into the elevator :P.
Please do not throw it away! Some beautiful engineering here that needs to be preserved!!!
I know a kid whose parents let him have these things in their basement.
"Don't take it apart, turn it on!"
when you were pulling the fiber loop backs out of the I/O cage, I expected this calm voice to come out of the mainframe saying" What Are you doing Dave?. . . . . ." 😆
Did you know that IBM is only one letter in the alphabet apart from HAL ?
@@PlaywithJunk i had heard that in a video. pretty Awesome!
@@GothGuy885 Yeah and IBM sponsored "2001" heavily. All the graphics have been made on IBM machines.
That swing arm for dual laptops.. is just peak over engineering.
@pixelflow
You're getting what you're paying for with these machines.
oh sorry i dropped the laptop when i was stressed out fixing this $5M computer that your 10000 employees are waiting to use again. i can't work now since i broke the $1000 thinkpad.
not over engineered.
In old hardware, best I have is a 48U DEC AlphaServer 4100 frame that used to belong to Softimage. It had been gutted but still has it's ceiling fan. It's now populated with a single HP ProLiant 380L Gen4. It's noisy AF like this IBM frame. But makes A great Linux GIT server for in-house use. Plus it makes people's eyes pop-out.
I'd love myself a full frame like this one. Kudos for keeping it alive.
brings back fond memories. Thanks for sharing playing with junk!
I bought one of these for cheap, i told my son i'm building a nuclear missile facility in our basement, you should see the look on his face hahaha.
😂😂
The license agreement window will automatically close on February 29th, allowing you to continue booting.
Simply Beautiful. Thanks for posting this.
Worked on these from the S/390 up to the zEC12. Loved this archaic monster.
It's hard to believe someone could trash such a beast :O
A beast that built like a tank, weight of a car, sounds like a plane and performance of a raspberry pi 4 . :-)
@Fabian Matias Greevey
I can believe someone could trash it. A few years ago I saw a mainframe that looked pretty similar to this being sold at a local computer store. I didn't have the space for it else I probably would have bought it.
@@TonyLee_windsurf and the electricity consumption of a small city ;-)
Wow, the thing that threw me the most was seeing OS/2 Warp... I busted out laughing when I saw that... as I remember working a job patching OS/2 Warp machines to prepare for Y2K. I was surprised it wasn't running a Linux based HMC like they have on their midrange POWER machines.
Two of my servers run an updated version of Warp (eComStation). Rock solid for what they do. Last reboot - a year ago. :-)
WOW THAT'S LOUD! It sounds like a 747 Jumbo during take off.
Well, I think that one would be a little bit louder :-)
They might have still used modems for calling in service calls at the time. When I worked in the zSeries test lab 12 years ago we still had a lot of the modems in our storeroom. Used one for dialup at home until we got broadband. I know the pSeries systems still used serial management up through Regatta/Power4, then Power5 was when everything went to ethernet-based (the 24" racks actually had an ethernet network just within the rack itself). That was probably 2004, so mainframe probably had that 2-4 years earlier.
Fascinating. The unused network port do have these loopbacks, so it can diagnose malfunctions in these ports, even if it is not connected to other equipement. Giving preemptive diagnostic.
Build them so well back then!
That cooling sounds very violent. Then it us turned on. Then the cooling sounds very more violent. I love it!
Beautiful tech as always! Thanks!
I love seeing things like this, its very rare to find these things. =3
Thank you very much, I really wanted to see this.
The kid that bought a mainframe has a job at IBMs mainframe department now, isn't it?
Grammar bub.
a very energetic voice, enough to pump you up in the morning... and quickly put you into sleep... :/
Still crunches thru our night batch like nothing else... and that’s not counting the 500 application programs that have been “bullet tested” for DECADES - across the millennium - and would have to be re-written for millions of dollars... to do the exact same processing 😁
“WOULD YOU LIKE TO PLAY A GAME?”
How about TIC-TAC-TOE with zero players...?
The 2 laptops you have in the front of the Z-Series are known as the Service Focal Points. they are identical and redundant just like all the components in a mainframe are
Are they really laptops? Because a laptop wouöd have its own os, own everything, and these one look and behave like a rack console in the form of a thinkpad notebook
IBM training is so awful, they never really explained to us what a SFP was, you just learn to type commands and call engineers when it goes tits up.
from a command centre by the way, where I worked remotely.
@@legominimovieproductions Those are bog standard Thinkpad T30s connected to the mainframe via Xircom cardbus ethernet cards by the looks of it (I recognize those dongles). Those T30 Thinkpads are also pretty damn rare as it was the *only* Pentium 4 Thinkpad ever. There's only this one T30 model, unlike the series before it (T20/21/22/23 with various iterations of Pentium 3) or after it (T40/41/42/43 with various iterations of Pentium M and built in flexing problems across the board)
Sad these old systems get thrown in the trash...
thank you for taking it apart
The second laptop probably didn't start up due to the fan issue.
The latest PUs have a large single die rather than an MCM from what I understand. They are mounted in water cooled drawers. On the MCM you were showing, the four chips in the middle are the PUs themselves and the four others are the caches.
Your license terminates when you no longer rightfully possess the Specific Machine
When you don't posess the machine, you won't need the license anyway.
@@PlaywithJunk Don't get me started on that. Once phoned ibm from theatre to get a medical database off one of those and they gave a sh*t because "the license expired" ;) It's not like it was a couple of million bucks in the first place so they could at least forward me to a technician and bill us into oblivion ... but nooo ... No license -> You're f-ed... Hard. MacGyver-ed it myself to at least print the stuff we needed though :D
@@wissemaljazairi Not that easy in an active warzone. Especially if all those contractors the occupying army brought in cared more about their pound of flesh rather than keeping that important database up. My company fixes those disasters. Even in a red zone :) IF they're fixable.
@@wissemaljazairi **shrug** somebody's gotta do it ;)
I would love to have one of those laptops... :)
Yes, you can create Logical Partitions LPARs and run independent services in each: TSO, CICS, DB2 and IF you upgrade to z14 processors and zOS2.4 you can run a Cloud Service under Red Hat in a Unix System Service (USS LPAR) but the real reason these beasts will continue to function as a key part for major corporations is that that Cloud Service can retrieve legacy data from VSAM/IMS/DB2 data stores w/o going thru the TCP/IP stack... but cross memory using the Coupling Facility.
From the article about the kid who bought one of these, the cost of power to run it is $200/month.
That's easily possible when it's run 24h per day. The max. power is 4.2 kW, that's 100 kWh per day. One kWh here in Switzerland costs 10 to 40 cent.
@@PlaywithJunk 40 cents...that's insane.
@@douro20 Germany is worse, they want to get CO² neutral but with almost only renewable energy, no nuclear power "Energiewende" and we already got the second highest cost per kWh in worldwide comparison, save the environment at any price while the rest of the world (except a few other european countries but these won't abandon nuclear power) continues without listening to these FFF-fanatics.

4:50 - cool! Like a jetplane starting its engines :)
The Hitachi blade center is much louder. Well it's also made by IBM but with a Hitachi label...
4.2kW.. LOL..
Yes. IBM had great hopes with OS/2. I worked with it quite a bit back in the 90s. Mostly on PCs for desktop. It was actually far superior to Windows of the time. Version 2 was an actual 32bit protect mode multi-tasking OS. The problem was that it never caught on with software developers in the industry. OS/2 had the ability to run a Windows 3.1 session for the sake of running popular software but that had some limitations. Eventually IBM moved to using Linux for controlling their big iron, storage systems, etc.
It's like many other stories.... A good product does not take off because manufacturers did not recognise the potential or it just came at the wrong time.
Like Xerox who invented the mouse and the GUI. It could be the biggest company on earth now.
@@PlaywithJunk I think in the case of Xerox Park, the main company didn't really appreciate the full significance of what their west coast lab was creating and sold those things off cheap.. Hindsight is 20-20.
Yeah, fans failing in the T30 and T40 series is pretty normal. You blow out some dust, put some oil in the fan bearing to make them work again. There are also replacement fans on ebay in good condition or like new. But it is a pain to get to them, requires a lot of disassembly of the notebook.
Absolutely horrible things to troubleshoot, I had the pleasure of working on a set in Botswana for the Forex department of FNB bank in Gaborone. FYI working with a set of two does sound like the back end of a Boeing 737.
Yeah I guess the error messages are pretty cryptic.... Something like "ERROR 056725 IN DEVICE 0201" ...?
@@PlaywithJunk Not really if you got the books translating those. IF you can still find one that's not completely bleached out ;) Or if you can find one of the old (as in ancient) ibm guys knowing those by heart ;)
Rectifier circuit maybe? Capacitors? Just an idea ;) If it's unstable i mean ...
@@peterpain6625 The code at the side of a message will also tell you where it came from, the sequence of the message and the type of message.
@@peterpain6625 I remember the documentation for our mainframe; it was like a library with 300 thick volumes requiring its own dedicated room.
IBM probably didn't really want to use OS/2 here for the laptop, but the software was probably already there for their previous mainframes, and by using their own operating system and laptop they could provide full support, including security and long term support without relaying on Microsoft.
This reminded me of the many times I had to reboot a mainframe with a client on the phone which made it seem like it took twice as long to come up.
I know telephone support ;-)
Very interesting! Thank you!
The laptops to IPL etc used to run OS/2 then they went with linux and an interface that looks like the OS/2. Btw all models had every cpu and you call IBM to license more cpu power via the Golden screwdriver. You would connect to the drives vis Bus and tag or ESCON.
@VIDEOSUPERHIGHWAY
So the CPU runs at a default low speed until you get a special code to make it work harder? It kind of fits what I've heard about one paying for CPU cycles used, or something. I've heard IBM has crazy licensing terms for their mainframes.
Now we know were Elon got the idea for the Teslas.
Keysight does the same with their oscilloscopes.
He said he hoped it was very interesting and I must say without a doubt it was!!
700 kg! That is almost the weight of Smart. Or an old VW Polo.
Or F1
when a computer has DOUBLE LAPTOPS just for boot procedure you know it's serious
It is a pity that no one is saving these machines and those Thinkpads are well worth collecting due to their condition as most of that model are used up and beat to hell and back.
Very true! In forty-odd years there might only be a handful left on the planet for folk to look at (like the old ones on curiousmarc's channel). This IBM deserves a bit of love and preservation :)
:( I would have given it a good home, if I could have gotten it.
is that thinkpad laptop connected to KVM switch ?
Somehow I have flashbacks of my last airline flight where we were stuck on the tarmac for an hour :)
i would legit frame that Processor on my wall if i were you. in awe of the size of it, 'solute unit!
What a beauty.
it's like a damn airplane lifting off
04:42 - HP/Compaq MSA-30 and MSA-1000 on the rack in the background. That's some old SCSI kit these days.
Yes and some people still use them....
imagine being in a room full of them, you'd need ear protection!
You do, I'm the guy he mentioned in the video and well I work at IBM now and we have a raised floor with literally over 100 of these machines from different generations. You definitely need hearing protection, but there have been louder and quieter machines through the generations.
Conmega Oh wow you work at IBM now? That's awesome! I remember your story, so it's cool to know you actually get paid to work with that stuff now haha
If you don't mind me asking, did you go to them or did they find you?
@@leisergeist So at the convention I gave my original talk at I was approached by two people from IBM. Which I later found out was a high ranking executive and someone high ranking in the education sector of things. They were asking me why I was interested in the machines and such. I then asked if I could get a tour of the Poughkeepsie, NY plant. To which they looked at each other and confused asked how I knew about the place. Which of-course I knew about because I knew the history of the machines, this is where they have been making mainframes since the first S/360s. Anyway they said sure! Since I later found out that is why they came to me, to offer me a tour and at the place offer me a supplemental position. Which turned into a full time position when my skills were proven during the year long supplemental.
Also you can thank that executive for my talk being on RUclips in the first place. He said the talk should be on RUclips and I mentioned that I don't even think they were planning on recording my talk. Which he instantly went and talked to the right people and got a crew rushed in last minute to get the thing recorded. The room was filled out the door, which this is the first time I actually gave a talk outside of a public speaking class in college so it was nerve wrecking to say the least. At the end of the talk the executive stood up, said some nice things, then mentioned that this video should be on RUclips in a week. And oh yea... That talk was up a week later.... No other talks from the show were I don't think. Just this one because well, the entire conference was for IBM Mainframes, so when an executive from the ranks of the IBM Mainframe development sector says make it so I suppose it happens.
Quite funny how it all unfolded, but man it all happened pretty quick.
But of-course I'll doing all the same things I would have with or without the job. Still getting weird hardware/computers/etc and playing with them in my free time.
Though I don't really need to get another mainframe due to well having access to literally hundreds of them at work :)
Conmega that's fantastic, thanks for sharing!
@@Conmega1 Dude, you are a legend! It has been 3 years and your story still pops up randomly in conversations among IT students and professionals. A couple of times I've had drinks with classmates and later colleagues and someone would say "Hey, have you heard about that guy who bought a mainframe?"
May I ask what is it you actually do at IBM? Do you design electronics or write software? Or maybe you do networking?
You have so many cool things. I would like to use a couple of them or to work in your company :/
@47:52 you cut the label? I think you just voided the warranty! XD
The MCM power integrity rail design is presented visually in the groups of capacitors. You can see that the enclosure has a lot of vertical space available to put in much taller AL Electrolytic capacitors so why are there so many small AL electrolytics when you have all that room? The design is using a technique of parallelling the AL capacitors to achive an overall power rail impedance. My quess is all these small AL caps are in parallel and are as close as possible to minimize parasitic inductive effects relative to the PCB power plane design. It is strange that there is not the slightest spacing for cooling air flow between some of the AL caps given all the board space available.
If I Had Just One Of Those IBM Ceramics, I Promise I’ll Never Harm Another Computer.

There is always someone who counts the pins.... :-)
Yup. Same figure I got as well.
Interesting LGA Socket, the socket itself got no "spring pins" like all Intel or AMD LGA sockets, but this frame with wires instead and no integrated loading mechanism (ILM) you just screw it down.

IBM didnt use "sockets" for the cpu module. It was gold bumps that made contact
you mean just like in cpu sockets that have been around forever?
@@firecrow7973 since the P4, hardly forever. My first pc used a super socket 7 - an amd k6-2 400mhz. Also intel and amd still use alot of licenced tech from IBM even in their current cpus
@@firecrow7973 forever for who? PCs? Because of the hundreds of connections to each CPU module, IBM didnt use sockets, they used tiny gold bumps that mated with other gold bumps. The CPU modules were fastened down in thier respective locations by various means (clamps, screws etc) CPUs were not just one chip like PCs. A maimframe CPU was made of modules.
I want one for my home MIDI Studio :)
Not a spec of dust in that CPU book.
Well... I found a tiny bit of dust at the lower edge of the CPU cooler. :-)
These systems are used in air conditionned server rooms. There is simply no dust.

Watching the video of this incredible IBM machine, I wonder if any Linux user had the idea of installing the Unix System to reuse the hardware?
Were these two beautiful IBM notebooks saved?
They are the best ever made!

OS2 was a good OS. In what year was this machine manufactured?
dayum! look at all those caps!
What do you do with the old thinkpads? I'd love to get my hands on one of those.....
I use them as portable compters for the workshop. Stuff like firmware updates or configuration of switches and servers.
I built sperry 1180 mainframes that went to Scottland Yard, and to NASA for the shuttle.
I would love a mainframe like this but can never afford it. Lol but one cam dream. Its a beauty
To have it at home I would call it a nightmare.... not a dream :-)
Awesome. The one thing I would have changed: let the tests complete and copy back to the laptop, then post the results or at least scroll them on the screen.
The z/VM Evaluation Edition is delivered on DVD-RAM. You can also download the materials from the following URL
and copy them to a DVD-RAM: www.ibm.com/services/forms/preLogin.do?lang=en_US&source=zvmeval
This DVD-RAM must be inserted into the DVD drive of a System z10 Hardware Management Console (HMC) and used
to load a logical partition (LPAR). No external disks are required to start the Evaluation Edition or to perform simple
functions. However, in order to run any significant guest virtual machine work, external disks will be required for z/VM
paging and spooling, as well as for holding guest data.
The DVD-RAM contains a RAMdisk that holds data required to operate z/VM. A DVD-RAM is used to enable updates
made to this RAMdisk to be saved using the ramsave command, so that they are available the next time the system is
IPLed.
Holy shit we're taking off
