Yes another one…
Looks like 2009 is the year everybody wants comparisons!
So what’s the difference with this one?
Well here the testers only tested the hypervisors, which is the core of virtualization applications such XenServer, Hyper-V and ESX.
Other critical aspects of a virtualized environment like management tools, advanced features like VMotion, or third-party application availability were not taken into account.
Eventually ESX’s memory overcommit feature was tested but just FYI.
And what are the conclusions?
After doing these comparisons of ESX to Hyper-V and XenServer, it’s clear that at the hypervisor level, ESX is optimized for a large number of less-intensive workload VMs.
For intensive workloads that may not be optimized for memory overcommit apps, Hyper-V and XenServer should definitely be considered-even if that means adding another hypervisor into the data center.
In other words, go for ESX if you need to consolidate a lot of servers (high ratio), go for the competitors if you want to virtualize high CPU/memory applications.
