• Disk Type.
• SAS: Enterprise SAS.
•SAS MDL: Midline SAS.
NOTE: In the Configuration View panel, if a vdisk contains more than one type of disk, its RAID-level label includes
the suffix -MIXED.
If no vdisks exist, the table displays no data.
Volume properties
When you select Volumes in the System Overview table, a table displays the following information for each volume:
• Name.
• Serial Number.
• Size. Total size of the volume.
• Vdisk Name. The name of the vdisk the volume resides on.
If no volumes exist, the table displays no data.
Snap-pool properties
When you select Snap Pools in the System Overview table, a table shows each snap pool’s name, serial number,
size, free space, master volumes, snapshots, and vdisk name.
If no snap pools exist, the table displays no data.
Snapshot properties
When you select Snapshots in the System Overview table, a table shows each snapshot’s name; serial number;
source volume; snap-pool name; amounts of snap data, unique data, and shared data; and vdisk name.
• Snap data is the total amount of data associated with the specific snapshot (data copied from a source volume to
a snapshot and data written directly to a snapshot).
• Unique data is the amount of data that has been written to the snapshot since the last snapshot was taken. If the
snapshot has not been written or is deleted, this value is zero bytes.
• Shared data is the amount of data that is potentially shared with other snapshots and the associated amount of
space that will be freed if the snapshot is deleted. This represents the amount of data written directly to the
snapshot. It also includes data copied from the source volume to the storage area for the oldest snapshot, since
that snapshot does not share data with any other snapshot. For a snapshot that is not the oldest, if the modified
data is deleted or if it had never been written to, this value is zero bytes.
If no snapshots exist, the table displays no data.
Schedule properties
When you select Schedules in the System Overview table, a table displays the following information for each
schedule:
• Schedule Name.
• Schedule Specification. The start day and time of the schedule.
• Status. Expired or Active.
• Next Time. The next time the task is scheduled to run.
When you select a schedule, two tables display: the Schedule Details table and the Task Details table.
The Schedule Details table displays specifics about the schedule:
• Schedule Name.
• Schedule Specification. The start day and time of the schedule.
