DeprecatedWith Storage 10.0, Swarm is single-process only. This information applies only to Storage 9.x and earlier. |
This section describes how to enable the multi-server functionality in Swarm to create two or more independent nodes in a single physical chassis.
Platform ServerSkip this section if using Platform Server: the hardware is set up. |
Environments including high-density hardware with multiple cores benefit from the multi-server functionality available in the Swarm 3.0 and later releases. This feature allows multiple independent Swarm nodes in a single physical chassis with a subset of drives assigned to each node to be created.
For multi-server implementations, each node requires at least:
Two CPU cores
Two hard drives
2 GB RAM
NoteAssign a static IP address to a node if it does not boot from a CSN. |
See Configuration Settings for Multi-Server.
Shutting down or restarting one node impacts all nodes in the multi-server chassis after setting up a multi-server configuration. The entire four-node chassis restarts if a four-process multi-server chassis is set up and a single process (a single node) is restarted. This is true for both SNMP shutdown/restart and shutting down or restarting the chassis using the Swarm Admin Console because all services in the multi-server chassis share the same resources.
The Swarm Admin Console displays each physical chassis at the same level as a subcluster.
NoteUse the Shutdown and Restart SNMP commands or Admin Console actions after verification in a multi-server implementation. Restarting the chassis or shutting down a single process within it (which appears as equivalent to a node on the Swarm Admin Console) restarts or shuts down all associated processes on the same chassis because they share system resources. |
The Retire action impacts the volumes for the specified process.
Initiate retire actions for all associated server processes within the chassis to retire all volumes within a chassis.
