5 Essential Tips for Maximizing Your Experience at Nutanix .NEXT for Bloggers
Thanks! Here's what I have: Cisco Hyperflex 3-node connected into fabric interconnects via 40GB[img]https://d1qy7qyune0vt1.cloudfront.net/nutanix-us/attachment/5ac513d4-fb8b-4903-a249-61d06001ded4.png[/img][img]https://d1qy7qyune0vt1.cloudfront.net/nutanix-us/attachment/f7309969-48cf-4111-81e2-a1cac84a4418.png[/img] [img]https://d1qy7qyune0vt1.cloudfront.net/nutanix-us/attachment/578b5df3-8982-4b28-a311-002310b046cc.png[/img]

When I attempt to go to <foundation_ip>:8000/Foundation/docs I get a 404 error:The path '/Foundation/docs' was not found. When you say a persisted config that I could modify and try importing into Foundation...is there a way to export the config of an already configured environment? Sorry, this may seem an obvious question and I’m still fairly new with the platform.Thanks,Travis
Unfortunately I’m unable to test with 10 gig on a 2-node, but here’s a 2-node with 1 GB uplinks. Two uplinks used with one dedicated for storage traffic.
We don’t have a one-touch method, but use a mix of Foundation, NCLI and PowerCLI scripts. Use install.nutanix.com to build your JSON file for importing to Foundation (where maybe the initial creation could be more of a template) then we run a number of NCLI and PowerCLI scripts to complete various Nutanix-specific settings and PowerCLI on the ESXi/vCenter side. Nutanix has very good documentation for NCLI and just do a web search for what you are trying to do with PowerCLI as there’s a ton of examples out there. Specifically with IPs, we pre-reserve our IP addresses when filling out a Nutanix build-out worksheet we’ve created internally.
Be VERY careful when considering a two node environment. We’ve run into a number of caveats one of which I haven’t seen documented. When going through maintenance tasks (AOS upgrade, firmware upgrades, etc) we’ve seen what looks to be the data uncompressing when transitioning from a two node to single node cluster. I’ve attached a screenshot showing the storage usage of our container as it transitioned between two and one node clusters. I have a ticket opened with Nutanix to get clarification, but from what we see enabling compression is not a good idea when using a two node deployment. After having our deployment live for a few months I feel like it’s not ready for prime time yet. There are a lot of caveats vs. a 3+ node cluster and for what what you pay I feel like other HCI players do a much better job.
I wanted to provide an update on some testing I’ve done in our two node environment (running ESXi). From what we were seeing during previous maintenance tasks there was an increase of usage during two node → one node transition so I wanted to test this further. We have our container configured with “Advertised Capacity” at the usage threshold recommended by Nutanix in a two node cluster (40% which takes into account a node failure). I then filled the datastore to ~95% capacity and applied AOS 5.11.2.1 (coming from 5.11.2). During the upgrade process we did reach max capacity (the Advertised Capacity size) briefly, but it didn’t affect the VMs running. So I can’t really explain what’s happening behind the scenes, but I do feel better about leaving compression enabled. Even though the two node cluster has some caveats, Nutanix providing the ROBO option licensing on a per VM basis makes this an enticing option for a very small site. If you were to go with the full core/capacity
To be honest, I just redeploy using Foundation. It’ll warn you that the CVMs and hosts are pingable, but you just pass through it and it’ll destroy everything and rebuild from the ground up. We used to go through the process of stopping the cluster, powering down the CVMs, etc., but if you’re looking to redeploy anyways going the graceful route of shutting everything down didn’t make sense.
I know this is pretty old, but I wanted to provide an update. IPMITOOL also works for HPE iLo so come to find out we could use the same code. That link worked, but clicking on the “Download” button took me to a “product not found” page. This one worked for me:Software Details - Scripting Tools for Windows PowerShell (x64): iLO cmdlets | HPE Support
