OS Patches & Upgrades

NCache provides a systematic framework for performing Windows and Linux system upgrades without compromising cluster liveness. By leveraging NCache Maintenance Mode, administrators can transition a node into a protected state where client requests are seamlessly diverted to replica nodes. This allows for the application of security patches, kernel updates, and hardware maintenance with Zero Data Loss, as the cluster orchestrates intelligent failover and re-hydration logic during the node's offline window.
