Upgrading Zerto Clustered Environments
With a clustered ZVM environment running, you are able to easily upgrade your Zerto Virtual Manager.
Clustered Concepts
TERM OR PHRASE | DEFINITION |
---|---|
clustered role | Clustered applications and services |
node | Clustered nodes (meaning, servers) are connected by physical cables and by software. If one or more of the cluster nodes fail, other nodes begin to provide service continuously. |
Active/passive node | A resources cluster where only one instance is active at any given time. |
Zerto Failover Cluster Role Mover | The Zerto Failover Cluster Role Mover tool facilitates an unobtrusive move of the clustered role from one node to the other, with minimal consequences to Zerto Virtual Manager. |
switch node | |
Microsoft Failover Clustering | A Windows Server feature that enables you to group multiple servers together into a fault-tolerant cluster(renamed in Windows Server 2008 from Microsoft Cluster Service (MSCS)). |
Minimal downtime | The time it takes for the ZVM to start. |
