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.
Generation 6 (G6) Hardware for NX-1065 and NX-8035
Last week Nutanix published more info on G6 hardware NX-1065-G6 and NX-8035-G6. Support Portal NIC replacement instructions (requires login) contains detailed information on various NIC options and also front and rear view drawings of the new G6 hardware.
Nutanix seems to have done a soft launch for the next generation G6 hardware. I haven’t seen much marketing around this, but some information is already trickling down. For example HW specifications of G6 platform are already available at Nutanix website.
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.
Finally got my hands on AOS 5.5 and upgraded our lab Nutanix cluster to this version.
In my earlier post I described how to manipulate “iptables” rules to allow access to “Stargate” or “port 2009” pages. Stargate page contains lots of detailed information of I/O operations, more info in my earlier post. It seems that “iptables” configuration has changed in this version.
In versions prior AOS 5.5 “iptables” chain used was called “WORLDLIST”. In AOS 5.5 the name of the chain has changed to “MGMT_OPENFROMALL”. This requires changes in “iptables” commands used.
For some reason I managed to upload images into Nutanix AHV image catalog that were corrupted. This might be a browser related issue, I have to do some digging in order to find root cause for the problem.
One symptom of image corruption was that all the controls for the image were missing from the Prism GUI. The image was there, but no controls and there was no way to remove the corrupted image.

- Launch acropolis CLI: acli
- List images: image.list
- Delete images: image.delete
