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.
