Configuring Edges for specific LUNs
After you configure the LUNs and Edges for the Core, you can map the LUNs to the Edges. You complete this mapping through the Edge configuration in the Core Management Console Configure > Manage: Edges page. When you select a specific Edge, the following controls for additional configuration are displayed.
Status
The panel also displays a small-scale version of the Edge Data I/O report.
• IP Address is the IP address of the selected Edge.
• Connection Status is the connection status to the selected Edge.
• Connection Duration is the duration of the current connection.
• Total LUN Capacity is the total storage capacity of the LUN dedicated to the selected Edge.
• Blockstore Encryption is the type of encryption selected, if any.
Target settings
• Target Name displays the system name of the selected Edge.
• Require Secured Initiator Authentication requires CHAP authorization when the selected Edge is connecting to initiators. If the Require Secured Initiator Authentication setting is selected, you must set authentication to CHAP in the adjacent Initiator tab.
• Enable Header Digest includes the header digest data from the iSCSI protocol data unit (PDU).
• Enable Data Digest includes the data digest data from the iSCSI PDU.
• Update Target applies any changes you make to the settings in this panel.
Initiators
• Initiator Name specifies the name of the initiator you are configuring.
• Add to Initiator Group selects an initiator group from the drop-down list.
• Authentication selects the authentication method from the drop-down list:
– None—No authentication required.
– CHAP—Only the target authenticates the initiator. The secret is set just for the target; all initiators that want to access that target must use the same secret to begin a session with the target.
– Mutual CHAP—The target and the initiator authenticate each other. A separate secret is set for each target and for each initiator in the storage array. If Require Secured Initiator Authentication setting is selected for the Edge in the Target Settings tab, authentication must be configured for a CHAP option.
• Add Initiator adds the new initiator to the running configuration.
Initiator groups
• Group Name specifies a name for the group.
• Add Group adds the new group. The group name displays in the Initiator Group list.
Servers
This panel displays information about ESXi and/or Windows servers connected to the Edge, including alias hostname/IP address, type (VMware or Windows), connection status, backup policy name, and last status (Triggered, Edge Processing, Core Processing, Proxy Mounting, Proxy Mounted, Not Protected, Protect Failed).
If you have configured server-level backups, a manual backup for any server that is added to a backup policy must be triggered from this tab (as opposed to the LUNs tab for LUN-level snapshots).
Prepopulation
The prepopulation schedule is applied to all virtual LUNs mapped to this appliance if you do not configure any LUN-specific schedules.
• Schedule Name specifies a task name.
• Start Time selects the start day and time from the respective drop-down list.
• Stop Time selects the stop day and time from the respective drop-down list.
• Add Prepopulation Schedule adds the task to the Task list.
