Web-Scale and converged platforms that support large-scale deployments must embrace and provide architectural considerations for no single point of failure or bottleneck for management services. Tolerance of failures is key to a stable, scalable distributed system, and ability to function in the presence of failures is crucial for availability.
Some Nutanix customers are running just three nodes, but others are running thousands of nodes and at that scale automation is fundamental in being able to manage clusters, datacenters and operations properly. More importantly it is crucial that platforms that operate at that scale be able to identify potential conditions and problems before they affect resiliency or availability.
I have previously introduced NCC, but let’s re-cap. NCC is a framework that serves as the engine for the Nutanix Cluster Health. It consists of various modules and plugins. The modules are groups of plugins that correspond to a specific test category. NCC can be run as long as individual nodes are up, regardless of cluster state. The scripts run standard commands against the cluster or the nodes, depending on the type of information being retrieved.
If you want to learn more about NCC read NCC 1.1 is available for download Now and it boosts Nutanix Cluster Health.
In every NCC release, Nutanix adds new plugins/checks to detect anomalies in the cluster and report any issues. Today Nutanix is releasing NCC 1.2, which include the following features/enhancements:
- Microsoft Hyper-V hypervisor support
- Nutanix OS (NOS) versions 3.5.3, 3.5.4, 4.0.1, and 4.02 only and includes a new installer to help you upgrade your NCC version
- Nutanix Models NX-1020/1050, NX-2000/2050, NX-3000/3050/3060, NX-6060
- Dell XC Series of Web-scale Converged Appliances
- New checks help you to proactively test your cluster, ensuring your environment is operating optimally
