Please read again. I am not spreading info, I am requesting info. As VMware/EMC licencing prohibit benchmark publications, nor do they provide such information, I am trying to find what the underlining differences are. Consider, if you will, the differences between MS-Exchange standard and enterprise additions. It is the same application with hard coded limits in the standard addition. I.e. it is a marketing and not a technical issue. Data-Ontap (netapp) has all functionality built into the core OS, it only has to be licences. Again, a marketing decision. > > note: i didn't deal with GSX other then reading about it. i did, however, > had the "pleasure" of trying to disect ESX for some purpose, and was quite > surprised to find how it works. If I understand you correctly, then ESX is similar to XEN in the sence that there is another Kernel running in ring 0 and that the console OS is a privileged (Dom0 in XEN talk) guest. GSX would then be closer in concept to UML or QEMU. > > -- > guy > > "For world domination - press 1, > or dial 0, and please hold, for the creator." -- nob o. dy > ================================================================To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
