19. Web NxUI Walkthrough
This section provides a visual walkthrough of the SF Archive Web User Interface (UI).
The NxUI has 11 areas of display.
View | Description |
Status | This page displays an overall status of the system, giving the user a view of such things as overall space available and used, number of jobs currently running, IO rate of the system, number of jobs, passed, failed etc. |
Queue | This displays the current queue workload, giving details about which jobs are currently being processed, are queued or have completed. Each job can be examined via is log, and re-run if necessary |
Workflows | Allows the user to display add and delete workflow assignments. Displayed are the process, what action it takes, and the %age progress made so far in doing so. |
Browse | Shows an ‘Explorer’ view of the archive, allowing the user to ‘browse’ its contents. Right click on the pane shows a submenu allowing a user to either restore the selected media or show information about what would happen should it be restored. |
Search | Search is the main ‘manual’ way of searching and restoring media from the archive. It is a simple wildcard search mechanism which displays results and allows the user to select and restore them. |
Servers | This is a view of the servers within a cluster and their status. Each server runs the Linux services specified and these can be stopped, started or disabled as wished. Disabling a service allows a cluster node to be removed and serviced whilst the cluster continues to function. |
Groups | Shows the logic group names for sets of volumes. It enables the user to create groups, add volumes to them and display the capacity and space remaining of each group. |
Volumes | Display all volumes, of any type, S3, tape, ALTO and so on under a single window. Volumes can be examined for their content, formatted and set to direct access (at the block level rather than using LTFS). |
Drives | Shows the tape drives contained across all robotics in the system. The window allows drives to be disabled or set read-only should a drive be designated as ‘Restore’ only. |
Changers | Shows all robotics within the system, their serial numbers and geometry. |
Admin | A simple window displaying administration features such as the licence, duplicate copy suffix and WebUI port number amongst other things. |
