Virtualization technologies such as VMWare, virtualizes resource at the OS/Hardware level only. MoreVRP granularity is 2 levels deeper – at the application level (Database) and at the transaction level.
Using VMware, you can prioritize between two or more operating systems competing for the same hardware resources. When adding more CPU power to a specific OS, all applications and transactions within that OS compete for the added resources. VMware doesn’t allow you allocate resource to a specific transaction within the VM.
More is capable of managing Databases that resides on VMs and by that – better utilize existing Virtual machine server.
In addition, the overhead of VMware and other virtualization vendors, affects dramatically the overall performance of databases and applications. MoreVRP overhead is just - 0.5% of a single CPU (less than one percent) – which makes it the best cost effective virtualization solution.
