| title | 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 ServerIf you useSkip this section if using Platform Server , skip this section: yourthe hardware is set up. |
Environments that include including high-density hardware with multiple cores can benefit from the multi-server functionality available in the Swarm 3.0 and later releases. This feature allows you to create multiple independent Swarm nodes in a single physical chassis with a subset of drives assigned to each node to be created.
Requirements
For multi-server implementations, each node requires at least:
Two CPU cores
Two hard drives
2 GB RAM

See Configuration Settings for Multi-Server.
Effect of multi-server
After you set up a multi-server configuration, shutting Shutting down or restarting one node impacts all of the nodes nodes in the multi-server chassis . For example, if you set up after setting up a multi-server configuration. The entire four-node chassis restarts if a four-process multi-server chassis is set up and restart a single process (a single node) , the entire four-node chassis restartsis 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.

|---|---|
| title | NoteIn a multi-server implementation, useUse the Shutdown and Restart SNMP commands or Admin Console actions with careafter 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 only the volumes for the specified process.
To retire all volumes within a chassis, initiate retire Initiate retire actions for all associated server processes within the chassis to retire all volumes within a chassis.
