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.

When making my custom Nutanix stencil package I ran into problems with shape sizes. Larger shape sizes increase the time to pull the shape from stencil to drawing. The more complex shape (with multiple sub-shapes) you have the larger it will be. Some of my original Nutanix shapes became so large that it took few minutes to pull shape into a drawing.

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.

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.
