HP Storage Essentials SRM 6.0 User Guide 389
Command View version v7.01, or later, is highly recommended to take best advantage of the
enhancements. The required Command View EVA versions support the new built-in provider, which
replaces the SMI-S provider used previously for EVA array discovery.
For Command View versions prior to v7.0.1, there is a maximum of 8 EVA arrays supported per
Command View EVA server.
The maximum number of vdisks supported per EVA array is 512.
NOTE: You must discover your EVA arrays for the Array Performance Pack to work.
EVAPerf Data Collector Requirements
The management server requires the EVAPerf Data Collector (EVA Perf) service to be running on
each Command View EVA server being monitored. This service is installed by default with the
Command VIew EVA suite, but sets the service to “enabled” and “manual startup”. It does not
automatically start the service. Therefore, you may want to consider changing the service startup
parameters to “automatic” and “restart on failure”.
Although EVAPerf version 6.0.2 or newer is supported, it is strongly recommended that you run
EVAPerf version 7.0.1, or later, to take advantage of fixes for service crashes and instability.
RPC over Port 860 must be “enabled” in any firewalls between the management server and the
Command VIew EVA server(s).
Specifying Data Collectors
After applying Array Performance Pack licenses to the target EVAs, you must select which
corresponding EVA-specific “performance data collectors” to enable in the Data Collectors for
Performance page. Each EVA Storage System-specific row in the list of performance data collectors
represents a distinct set of performance metrics for the corresponding EVA array. When you start a
collector, you will be prompted for a sample interval and start time for the collection of the
corresponding metrics. This can be edited after a collector is started by selecting the icon for the
collector. Be aware the type, quantity, and frequency of data collectors started can affect system
performance. For example, EVA physical disk metrics collection is I/O intensive, so should be
avoided unless needed.
To choose collectors, click Configuration at the management software home screen, then click
Performance. When the Data Collection screen displays, click the Data Collection tab.
