Nutanix Acropolis hypervisor (AHV) vs Vmware vSphere hypervisor, AOS 5.5 edition

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.

Enabling Nutanix “Stargate” I/O statistics page access with allssh command, AOS 5.5 edition

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.

Visio by DPTPB: NetApp FAS / AFF Disk Shelf Stencil (V2)

Oct 24, 2017 Visio by DPTPB release update notes. Long over due documentation of new NetApp FAS / AFF Disk Shelf Stencil, already released back in May :=)

New DPTPB NetApp FAS / AFF Disk Shelf Stencil has by far the most complex internal structure, hopefully in favour of much easier shape usage. Besides standard V2 design changes, there is now much more automation and dynamic features with the new disk shelf shapes.

Nutanix AHV: removing corrupted images from catalog

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.

Solution:

  • Login into one of the CVMs as nutanix user
  • Launch acropolis CLI: acli
  • List images: image.list
  • Delete images: image.delete

Visio by DPTPB: 4-Node NetApp AFF A700 Fabric MetroCluster sample drawing

I’ve haven’t had pleasure to design a solution based on AFF A700 platform yet, maybe one glorious day… Quite often performance / capacity requirements can be fulfilled with lesser platforms like AFF A300 or even AFF A200.

Gone Golfing – see you in autumn

Woke up today and decided that life is too short and I’d like to spend my summer playing golf rather than working.

I have given two-week notice required by law to my current employer. If you have any outstanding business with me, please reach out within next two weeks. Other than that I’d like to thank all end-customers, resellers and various vendor reps that I’ve had pleasure to work with.

What will you do next?

Don’t know yet. My plan is to take it easy for few months and start serious job hunting around August – September timeframe.
