Nutanix has updated most of their appliances to G6 hardware using Intel Skylake processor family. Previous G5 Nutanix appliances were using Intel Broadwell processor family. This has caused some confusion when it comes to processor performance, the newer processors typically run at lower clock speed, so quick conclusion would be that the newer processor would be slower.
One of the improvements that came along with Nutanix AOS 5.5 was IO path optimization feature called “AHV Turbo”.
While the marketing department at Nutanix might have fallen asleep and woken up in 1990s with god-awful name like this, it is actually a GOOD feature. Every time I hear word “Turbo” in IT related matters, it just reminds me of my first ever PC, a 286 with a “Turbo” button, which supposedly boosted performance by increasing frequency from 8 Mhz to 12 Mhz, but did actually do diddly-squat 🙂
Third installation of this popular post comparing Nutanix Acropolis Hypervisor (AHV) and Vmware vSphere Hypervisor. This version is based on Nutanix AOS 5.5 version. Earlier versions of this post can found by clicking following links: 4.6 and 5.0.
There are still some use cases where using Vmware with Nutanix platform is required. But the list is getting smaller and smaller and there are less and less reasons to pay hypervisor licensing fees.
UPDATE: This information is based on older AOS 5.0 version , for comparison between AOS 5.5 and Vsphere, plese read updated version
Few months ago I compared Vmware against Acropolis Hypervisor. At that time I listed ten use cases or features where Vmware was better or the only option as Hypervisor in Nutanix environment.
Now that Nutanix is about to release new version of their operating system, AOS 5.0, it is time to revisit this topic again.
UPDATE: This information is based on older AOS 4.6 version , for comparison between AOS 5.5 and Vsphere, plese read updated version.
For most implementations requiring basic hypervisor functionality Nutanix KVM-based Acropolis Hypervisor (AHV) is a good choice, even with some functional benefits over Vmware vSphere, cost wise AHV is hard to beat as it comes for free with Nutanix system. Please visit Josh Odgers’ blog for a good description of benefits using AHV.
However there is less information available on cases where Vmware hypervisor might be better fit or the only option. Like always there are fringe cases where a solution isn’t optimal or doesn’t fit at all, that is true also for AHV.
