AOS 7.6 expands scale, strengthens resilience, and simplifies infrastructure management. This release introduces larger deployment limits, improved cluster availability, centralized storage management, and important security enhancements, along with broad reliability improvements across the platform.
Review the detailed release notes before deploying any product updates.
New
- Scale all-flash NVMe deployments up to 307 TB per node for larger, high-performance environments.
- Increase hybrid node capacity to 270 TB for greater storage density and more efficient cold and warm data tiers.
- Choose new 1 Node / 2 Disk (1N/2D) fault tolerance to balance resilience and usable capacity.
- Expand two-node AHV clusters to three nodes with a simple node addition.
- Support RHEL 9 for Controller VMs and Prism Central to deliver a more secure platform foundation.
- Scale high-density systems to 40 EDSFF NVMe drives per node.
- Manage external storage directly from Prism Central, eliminating the need to switch to Prism Element.
- Add native support for Dell PowerStore as external storage for Nutanix compute clusters.
- Enable disaster recovery for Dell PowerStore, including synchronous and asynchronous replication and live migration between clusters.
Improvements
- Enhance cluster resilience with expanded 1 Node / 1 Disk (1N&1D) fault tolerance for larger clusters while reducing storage overhead.
- Improve security with Secure Access, giving administrators centralized control over SSH access and support sessions.
- Extend Controller VM security protections to Nutanix Cloud Clusters (NC2) for more consistent security across deployments.
- Automatically upgrade eligible protection domains to Autonomous NearSync, reducing manual administration.
- Support VMware vCenter Server 9.0 with ESXi 8.0 environments.
- Improve compute cluster availability by allowing services to recover automatically after multiple node failures when using external storage.
- Double supported virtual disk scale for supported Everpure FlashArray deployments through native Change Block Tracking offload.
- Prevent unsupported mixed-media storage configurations with built-in deployment guardrails.
- Display all reported health conditions for attached external storage to simplify troubleshooting.
Fixes
- Improve VM reliability during cloning, migration, failover, recovery, and upgrade operations.
- Increase the reliability of disaster recovery, replication, snapshots, and backup workflows.
- Strengthen external storage stability across provisioning, configuration, node removal, and storage management.
- Improve upgrade reliability for AOS, AHV, Prism Central, and Life Cycle Manager.
- Enhance networking stability and virtual networking operations.
- Improve Prism Central responsiveness and user experience with more reliable management operations and clearer error messages.
- Resolve numerous security, certificate, and vulnerability issues across the platform.
- Improve overall platform stability through fixes for storage services, cluster infrastructure, monitoring, and guest tools.
Additional Changes
- Update default alert thresholds to detect network issues more quickly and surface critical conditions sooner.
- Introduce usage restrictions for unlicensed clusters after defined grace periods.
- Announce the upcoming deprecation of legacy Nutanix APIs (v0.8, v1, v2, and v3), with migration guidance toward v4 APIs.
