- Glossary of terms
● Unallocated: The unallocated space for the disk groups, both total and by pool
● Uncommitted: For virtual disk groups, the uncommitted space in each pool (total space minus the allocated and unallocated
space) and total uncommitted space
Viewing host information
The host I/O panel in the footer shows a pair of color-coded bars for each controller that has active I/O. In each pair, the upper
bar represents the current IOPS for all ports, which is calculated over the interval since these statistics were last requested or
reset, and the lower bar represents the current data throughput (MB/s) for all ports, which is calculated over the interval since
these statistics were last requested or reset. The pairs of bars are sized to represent the relative values for each controller.
Hover the cursor over a bar to see the value represented by that bar.
Hover the cursor anywhere in the panel to display the Host I/O Information panel, which shows the current port IOPS and data
throughput (MB/s) values for each controller.
Viewing tier information
The tier I/O panel in the footer shows a color-coded bar for each virtual pool (A, B, or both) that has active I/O. The bars are
sized to represent the relative IOPS for each pool. Each bar contains a segment for each tier that has active I/O. The segments
are sized to represent the relative IOPS for each tier.
Hover the cursor over a segment to see the value represented by that segment.
Hover the cursor anywhere in this panel to display the Tier I/O Information panel, which shows the following details for each tier
in each virtual pool:
● Current IOPS for the pool, calculated over the interval since these statistics were last requested or reset.
● Current data throughput (MB/s) for the pool, calculated over the interval since these statistics were last requested or reset.
The panel also contains combined total percentages of IOPS and current data throughput (MB/s) for both pools.
Viewing recent system activity
The activity panel in the footer shows notifications of recent system activities, such as the loading of configuration data upon
sign-in, events with the Resolved status, and scheduled tasks.
To view past notifications for this PowerVault Manager session, click the activity panel in the footer and select Notification
History. For more information, see Viewing the notification history.
Viewing the notification history
The Notification History panel shows past activity notifications for this PowerVault Manager session. You can page through
listed items by using the following buttons:
Show next set of items
Reached end of list
