Does the term VMWare ring a bell?

[gizz72]

Greetings,
  An email I got for invitation for VMWare came. I'll paste the details below. Just tell me what you all think of VMWare?


IBM Xseries Server & vmware esx help customers win in the market place by simplifying their IT infrastructure through server consolidation. The combination of the two solutions is designed for server consolidation, rapid deployment of new servers, availability, and simplified management - - helping to improve hardware utilization, save space, IT staffing and hardware costs.

Through self-managing technologies, a scalable server architecture, and end-to-end solutions, IBM & vmware esx can help you "do more with less," freeing up resources, reducing costs and complexities, and managing multiple workload requirements.

Real Cost Savings to customers by allowing them to reduce the number of physical hardware units and thereby, save floor space, rack space, and power consumption; simplify the administration work of maintaining dissimilar operating systems and applications that require their own OS instance.
Highly Scalable & Flexible with VMware ESX Server*, you can enable dynamic, logical partitioning on your IBM xSeries™ systems. Instead of deploying multiple servers scattered around your company and running a single application on each, you can consolidate the physical servers into one or two big servers that are configured for high availability. This enhances system availability and flexibility at the same time because big servers are designed for scalability and expansion.
Centralized IT Management VMware allows one point of administrative control over multiple operating systems and applications.
High Availability These virtual machines are completely isolated from one another, if one virtual machine were to crash (e.g. for software reasons), the other virtual machines are not affected. In particular, when a new application is being introduced that is running older applications, housing the new application within a virtual machine insulates its behavior from disturbing the other applications.
Safe & Convenient Migration Migrating an application from one virtual machine running an older OS into another virtual machine running the upgraded OS does not require any physical interruption of operations. Physical network connections are not affected. The migration act is controlled from the console.


Tell me your opinion. Thanks to all.

 No, I'm not affiliated to any of this. It's an invitation. There're going to introduce VMWare to our company and other clients as well. Don't know much about it, but what I can see, I would like to share this to the community as well to get a few glimps of what it is. I've seen snapshots of Liunx running windows 98. AROS, I believe is considered VMWare too in that category. At least I need to know more on linux. I hardly have experience with such OS(linux) yet.
 Thanks for the opinion Jope. :-D

That's nice everyone, but just another thing. How many OS's does a VMWare can  run, I mean if read correctly 12 or 20 plus++ in one machine running a the same time? Does it affect performance when running different other OSes? (RETHAT + DEBIAN + BEos + Aros + UAE(probably) + Etc...) Is that possible on one machine? Just curious? :-?

[gizz72]

@sparky
  You're right about the UAE. It is CPU/memory/hd intensive. And you're right about the mirroring VM's, although it is slow, can imagine that. As long as the main system doesn't give up.
@all
 Which leads to another question. What if a scenario ever happens when the main system fails while mirroring VM's, Is it still possible to recover from a major crash(example). Would That 'mirror' still can run under such condition,take over or would also halt in the process? Such of which a cascading effect would occur possibly?

@Sparky
 I mean mirroring where one real and the other  running under VM as data center, whereby the 'real' one fails.

Likewise, you've answered the question, just cut and paste. Thanks. :-)

@Sethy
True, one good example is PearPC. Very slow x86 emulation.

Are there not PPC native versions of VMWares too? If so Why not try MacOS there as well? Could still run natively. In theory. Unless I'm wrong. ;-)


 Sorry: Very slow x86 emulation of PPC.
