In general, Cisco Compute Hyperconverged with Nutanix supports a select subset of UCS server firmware releases. Cisco periodically (approximately once every 6 months) qualifies the latest recommended version of UCS server firmware version. However, based on critical fixes, Cisco may qualify new server firmware thereby resetting the 6-month clock.

When a new AOS version is released, the latest UCS server firmware qualified for the Cisco Compute Hyperconverged with Nutanix solution is regression tested by Nutanix with the last qualified UCS server firmware version. If you are running a version of firmware not listed as supported by the version of AOS you want to upgrade to or deploy with, then you will need to upgrade or downgrade your server firmware.

When a new AHV version is introduced by Nutanix, it is regression tested with UCS server firmware last qualified with the Cisco Hyperconverged with Nutanix solution.

• ESXi Major Releases, for example, ESXi 8.0, 9.0: The goal is to qualify a new ESXi major version within 90 days of general availability.

• ESXi Update Release, for example, ESXi 8.0 U2, U3: The goal is to qualify a new ESXi update version within 45 days of general availability.

• ESXi maintenance patch (bug fixes): Customers are free to update ESXi with latest maintenance patch for a ESXi major and update release which is previously qualified. Cisco on a best effort basis qualifies the latest ESXi maintenance patch for an already supported ESXi major and update release every 6 months.

• ESXi security/express patch: customers are free to update ESXi with the latest maintenance patch for a ESXi major and update release which is previously qualified.
