HP XP Performance Advisor Software - Manual (Page 213)

Description Screen elements
Displays the SLPR group ID.
NOTE: SLPR does not exist in the P9500/XP7 disk arrays.
So, the SLPR group ID is displayed only for the XP disk
arrays.
SLPR Name
Displays
the port type, such as FCoE (applicable for
P9500/XP7
disk arrays) for the port ID.
Port Type
Displays the Ext-Lun provider's serial number for the array. E-seq(s)
Displays the maximum frontend I/Os on the port. Max IO/s
Displays the average of the total frontend I/Os. Avg IO/s
Displays the minimum frontend I/Os on the port. Min IO/s
Displays the maximum frontend throughput in MB/s. Max MB/s
Displays the minimum frontend throughput in MB/s. Min MB/s
Displays the average frontend throughput in MB/s. Avg MB/s
Viewing 90th and 95th percentile values for Continuous Access ports
The write data throughputs frequently display transient peaks beyond the average performance.
Sizing to these peaks can lead to enormous bandwidth provisioning and cost. Percentiles are an
effective way to exclude the impact of these transient spikes in the calculation of the bandwidth
requirements. In HP XP7 Performance Advisor, view the percentile values for the average MB/s
on continuous access ports and further estimate the required bandwidth for the continuous access
link.
If you have identified ports as CA Initiator and CA Target ports, in addition to providing data
pertaining to the average MB/s through that port, HP XP7 Performance Advisor also reports the
90th and 95th percentile values for average MB/s based on the CA Initiator and CA Target ports
performance data over a given duration. The corresponding values are displayed in the performance
graphs plotted for the average write MB/s of CA Initiator and CA Target ports. This helps you to
access the continuous access link bandwidth and the read, and write bandwidth of the continuous
access journal volumes.
NOTE: The graphs show the performance data for the last one hour. If there is no performance
data for the continuous access port in the last one hour or the average read, and write values are
zero, the 90th and 95th percentile values are not displayed.
To view the 90th and 95th percentile values for the continuous access ports:
1.
Click
Port Summary in the component selection tree for an XP or XP7 disk array.
2. On the Port Summary screen, navigate to the port whose Port Type is CA Initiator or CA Target.
3. Click the link for the value displayed under Avg MB/s.
The corresponding performance graph is displayed, where the 90th and 95th percentile values
are plotted.
