DX Object Storage Platform: Advanced Node Configuration Figure 4: Archive Storage Node Configuration Archive Archive Archive node becomes active when additional capacity is needed Archive Enabling Archive Mode To configure a Storage Node for archive mode, the Storage Node configuration file must be updated to enable archive mode. This is done by adding the name/value pairing for the archive mode option in the SN configuration file. The option name is "archiveMode" and the value is 1 to enable and 0 to disable. If the "archiveMode" name field is not specified in the configuration file, then the Storage Node operates in normal mode and objects are balanced across the Storage Node. Below is a sample of a SN configuration file that has been modified to enable archive mode. # # CAStor node Configurataion File # # Node: sn0026b9348cda # MAC: 00-26-b9-34-8c-da # archiveMode = 1 If the Storage Node configuration file is updated to enable archiveMode after the SN has boot up, the Storage Node must be restarted for the configuration to take effect. The DX Storage Admin Console Node Status Page indicates the Storage Node configuration for archive mode by displaying "archiveMode True" in the expandable Node Configuration section when the SN is configured to enable archive mode. The archive mode setting is a permanent state. The node will continue to adjust its bidding so that other Storage Nodes in the cluster that are not a full capacity will win the bids and take on new content. Note: Placing an active node that has data stored on it into "archive" mode will result in the bidding being raised so it the likely of it winning read or write bids is decreased. Page 6
