From time to time we have to run the Nutanix crashcart /usr/local/bin/network-crashcart to configure the AHV+CVM network IPs. This command has some guard rails in place to stop it working when the host is already in a cluster (very sensible!) but sometimes those guard rails are a little too tight and it doesn’t work even […]

Following on from a post outlining easier release vehicles we recently completed an AOS 7.0 upgrade for a customer, splitting the upgrades over maintenance windows – the last piece of the puzzle being the upgrade of Flow Network Security Next Generation 5.0 to 5.1. Flow Network Security ‘Next Generation’ (FNS NG) is deployed in a […]

Had an escalation this week where a customer was moving from ESXi on AHV on self-built new clusters. All built and tested (shifting from ESXi on 10GbE, to AHV on 25GbE and moving from leaf switches to TOR switches) – all OK in NCC and smoke tested fine. But… problems occurred quickly when loaded up […]

If you’ve ever designed a multi-site VDI implementation you’ve likely faced the conundrum of how to handle user profiles for your users, or rather, how to avoid their wrath when something is out of sync when you make the fact they’re connecting to multiple resource locations transparent to them. For years we’ve worked through the […]

(this has updated in March where Cisco C Series Rack + Intersight Managed Mode IMM is supported – https://itskimpossible.blog/foundation-central-1-7-1-cisco-imm-ahv-10-0-1/ ) As vendor agnostic picture painters, we at Cutter have deployed many vendor cloud infrastructure platforms on top of various server hardware vendors integrating with a plethora of network vendors. Whether it was blue, green, red […]

Nutanix recently introduced a new, simplified and altogether easier to work with support model for the Nutanix Cloud Infrastructure (NCI) product portfolio. Previously, customers had a choice between: Our recommended model for production installations was always to use LTS where possible, and to only consider STS if there was functionality you needed that wasn’t yet […]

Following our cluster installation on https://itskimpossible.blog/nutanix-ce-2-1-base-for-joy/ we now need to look at upgrading our software to the latest versions. Nutanix has a framework known as Lifecycle Manager (LCM) which allows for a consolidated and reduced risk approach to performing upgrades to the Nutanix platform and associated vendor firmware. Out of the box, LCM works in […]

A VMware VCF (OG VCF, pre Broadcom) customer is beginning their Nutanix journey with some retired Fujitsu RX2540 M4 VSAN nodes running Community Edition for their admins to get some hands one experience. I decided to chronicle this experience – first stop https://portal.nutanix.com/page/documents/details?targetId=Nutanix-Community-Edition-Getting-Started-v2_1:top-welcome-ce-c.html to confirm the licensing / EULA that lets us run in test/learn […]

Srinath GS welcomed us into the Nutanix Central Deep Dive session. What are customers asking for when it comes to managing larger Nutanix / Multi-Prism Central deployments? Srinath showed a live demo of logging into a single cloud facing URL, and being able to manage several Prism Central’s and many more underlying clusters directly. Slick. […]
