Caution
Avoid filling up LUN to its storage capacity as this may cause the system to become unresponsive
Storage Trend (Data Reduction)
Storage Trends are used as a predictive tool to approximate how many days of storage use remain before
the storage array is fully saturated. Trends are based on data captured daily on the amount of storage
remaining.
Prediction strengths of high, medium and low probability are based on the quantity of data points and
regression analysis validation. If enough data has been collected, the Storage Trend graph draws a
statistically valid regression line, for example, 30 days of data points yields a prediction probability with
a high strength.
Trend calculations without sufficient or with inconsistent data points will be calculated, but can be
statistically weaker or inconclusive. If a calculation cannot be made based on the data points, a message
appears to indicate this status.
Physical Space Alerts
The status of physical space is monitored on an hourly basis. Alerts are triggered at the capacities and
frequencies listed in Table 3-2, “Capacity Alerts,” on page 9. These messages can be viewed from the
Array Configuration menu under Alert Admin. Alerts are also sent to Autosupport and to the additional
addresses provided in the Autosupport CC field on the Support Settings window. For information on
alerts and how to suppress them, see See “Alert Admin” on page 12.
iSCSI Settings
The iSCSI Screen Lists the IP addresses by which an Initiator (a host) is allowed to access an Invicta
appliance.The two columns represented on the window are:
•
Allowed Portal: Lists IP addresses to which a host is allowed to connect.
•
Available Portal: Lists all available IP addresses of hosts that can used to initiate a session.
