This script reports the performance of virtual disk arrays of Dell Powervault MD38 Series, but in principle it should work with MD34 Series.
Prerequisites: smcli on a windows machine and a Nagios compatible agent

Version 0.1
This script uses smcli to check the overall storage performance
Currently there are no status codes returned so its mainly for information alerting
It filters the objects and retains info only regarding the virtual disks

Metrics:
Current MB s/sec Current IOs/sec Current IO Latency

If you use a high availlability cluster of controllers then the output will be only the relevant virtual disks assigned to each controller at each given time
So you will be able to see which virtual disk is assigned to each node and its performance data

You might need to change the path to the smcli executable on your checking device, usually you could perform the check with an agent on the machine the management software is located.

Sample Nagios Command
$USER1$/check_ncpa.py -H $ARG1$ -t $ARG2$ -p 5693 -M 'plugins/check_smcli_dell_storage_performance.ps1' -a "$HOSTADDRESS$"

$ARG1$ IP_of_smcli_capable_windows_machine
$ARG2$ token
$ARG3$ IP_of_storage
