Prism Central is a multi-cluster manager that provides a single, centralized management interface for Nutanix environments1. Prism Central can be deployed in different configuration scenarios, depending on the network and security requirements of the environment. Some of the valid scenarios are:

Environments use Network Address Translation (NAT): NAT is a method of mapping one IP address space to another by modifying network address information in IP datagram packet headers while they are in transit across a traffic routing device2.NAT can be used to enable communication between Prism Central and Prism Elements that are in different networks or subnets3.For example, Prism Central can be deployed in a public cloud and use NAT to access Prism Elements that are in a private data center3.

Prism Elements and Prism Central are in different subnets: A subnet is a logical subdivision of an IP network that allows multiple networks to share a single physical network4.Prism Elements and Prism Central can be in different subnets as long as they can communicate with each other through routing or NAT3.For example, Prism Central can be deployed in a management subnet and access Prism Elements that are in different application subnets3.

Environments do not have Internet access: Internet access is not required for the deployment of Prism Central, as long as the environment meets the prerequisites and considerations for installing or upgrading Prism Central. For example, Prism Central can be deployed in a dark site, which is an environment that does not have Internet access or has restricted Internet access. In this case, the administrator needs to manually enable microservices infrastructure and download the required software packages from another source.

Nutanix supports two types of deduplication: post-process and inline. Post-process deduplication runs periodically on a schedule and can be enabled on any cluster. Inline deduplication runs in real time before data is written to disk and can be enabled only on all-flash clusters.

Therefore, by checking the type of storage and the type of deduplication, you can determine if you can enable inline deduplication on a storage container or not.

Nutanix inline deduplicationis a feature that reduces the stored size and avoids duplicate data on a storage container1.It is recommended only on some specific scenarios, such as when using Nutanix Files or virtual desktop infrastructure (VDI) workloads12.

The node is automatically re-imaged using the software currently running in the cluster. This is because Nutanix supports a feature calledAuto Re-Imagethat allows adding nodes with different AOS versions to an existing cluster without manual intervention. The Auto Re-Image feature detects the AOS version mismatch and automatically downloads and installs the same AOS version as the cluster on the new node. This ensures that the cluster remains in a consistent state and avoids any compatibility issues.

inline compressionis a technique that compresses all incoming write I/O operations over 4 KB inline in the persistent write buffer (oplog)23.This approach enables you to use oplog capacity more efficiently and helps drive sustained performance2.From AOS 5.18 onward, inline compression (compression delay=0) is enabled by default for all new containers24.
