I want to know if it is possible simulate a SO inside of a T5220.
Because two servers are needed with different specific software that works on a T5220, but there is only one T5220 physically with one hard disk and the software works on solaris 10.
I am new in this kind of themes, but simulate this kind of platform in an x86 architecture is possible? Because there are servers of this kind available for this use.
I am seeking for all kind of options.
The software also is compatible with the next platforms: SunFire V440, Netra T2000, Netra 440 and Sun Fire X4270 M2. Any of those can be simulated? and if it is possible, what do i need?
You can create both multiple logical domains and multiple zones on a T5220.
With logical domains (Oracle VM for SPARC), you simulate different physical machines, each one with its own Operating System.
With zones, you have OS level virtualization including the ability to simulate older Solaris releases with S9 and S8 branded zones.
On the other hand, I'm not aware of any usable and current Solaris on SPARC emulation layer available for x86.

I am trying to replicate an ubuntu OS which is has (NAT,Firewall etc) setup.I am trying to find away to install a preconfig os or the os image in production, to avoid installing and setting up manually in each and every machine.Is there a way to solve this problem?
Thank you
Two methods come to mind--both variations on a theme. There may be other better methods that others know of, but lets at least start with the following.
Method #1. Assuming that the hardware is exactly the same between systems, you may be able to copy an install from one disk to another (or clone it using 'dd').
Method #2. If you are using virtual machines, you may have a master copy that you copy as needed (instead of identical hardware, you have identical virtual hardware).

I have an application that formerly was running on an itanium suse 11,
I'm wondering to now Can I freely choose suse 11 intel support on new intel cpu?
what I mean is that , is there any chance that application affect by changing cpu type but not the operating system it use?
The compiled binaries will not run on both x86 and arm. However, it is very possible to compile binaries for each platform from the same source code. How likely this is depends on too many factors to list here; you will have to try compiling it yourself. Depending on the language, cross architecture compilation will have varying difficulty. With Java or Python or something similar, the architecture is unlikely to cause problems as long as your are on the same OS.

I am too frustrated when i discussed about Android.
Internet searches strongly says it is Operating system but also some searches says it is Mobile software.
What is Android in actual. Mobile Software or Operating system ?
Confused.
Its a open source mobile operating systems targeted for mobile devices such as smart phones and tablets.
Internet searches strongly says it is Operating system but also some
searches says it is Mobile software.
That is both correct, software includes OS.
If you think of it in OOP terms, Android will inherit from 'Software' and 'Operating System'
You can read more in the SO info page of Android tag
Android is an operating system, based on the same kernel as Linux. It is optimized for low power operation, and for a small memory footprint. You can get developer tools online.

I'm told, that Windows NT was first designed to implement the microkernel architecture, but moved away to hybrid kernel.
What caused the change? I'm having trouble trying to find any info about this.
The main reason that Windows NT became a hybrid kernel is speed. A microkernel-based system puts only the bare minimum system components in the kernel and runs the rest of them as user mode processes, known as servers. A form of inter-process communication (IPC), usually message passing, is used for communication between servers and the kernel.
Microkernel-based systems are more stable than others; if a server crashes, it can be restarted without affecting the entire system, which couldn't be done if every system component was part of the kernel. However, because of the overhead incurred by IPC and context-switching, microkernels are slower than traditional kernels. Due to the performance costs of a microkernel, Microsoft decided to keep the structure of a microkernel, but run the system components in kernel space. Starting in Windows Vista, some drivers are also run in user mode.

I need to learn the basic knowledge of OS, kernel and CPU architectures since some jobs do require those background.
Is there a good book or online resource that I can refer to.
I don't know if you had a specific OS in mind, but one of the best books on how the Windows operating system works "under the hood" is called Windows Internals. It describes in detail how everything from the kernel, to device drivers, and the file system all work.
If your looking for a good book on how CPUs and processors work, in general, I recommend Computer Architecture: A Quantitative approach. Very good info there!
Also, some good resources on how CPUs work, with perspective to programmers, can be found from the Intel technical library. Everything is free to download there and it makes for some good reading!
