As any regular reader will notice, we trying to make the readers understand about the relationship of Processor and Server Virtualization Technology. In the preliminary articles, another author has written about the processors, then I on Processors capable of Server Virtualization. This series will end with Cloud Computing. If any reader readers from the first post to the last of this Processor series, will understand the whole technology.
Server Virtualization and Intel VT-x Processor (VT-d and VT-c)
Intel VT is being delivered by Intel with various added proprietary technologies and is targated for server virtualization. The reason is, the usage of Server Virtualization will increase in next few years.
Intel VT-x is used for x86-based Xeon series of processor, and Intel VT-i for Itanium based models.
- VT-d means Virtualization Technology for Directed I / O
- VT-c means Virtualization Technology for Connectivity
More on Server Virtualization and Intel VT-x Processor
Intel VT-x Xeon CPUs has important new features for an efficient server virtualization on x86-based systems. For a virtualization ring, a software layer is implemented, the communication between hardware and guest operating systems have to be controlled.
If the processor is not optimized for server virtualization, guest operating systems is running will create hardware level conflict.
The importance of the newer Intel VT-x Processor lies within the fact that, despite VMware or Virtuozzo has excellent tools, Server Virtualization can not run at the full throttle if there is processor level conflict.
This is what makes bigger hosting brands unique on the quality of Server Virtualization. Bigger Hosting Brands changes the Processors to run the Server Virtualization environment properly.
The biggest point you will notice in any imperfect server virtualization among the cheaper hosting brands – the cPanel WHM loads very lazily.
