Thanks to Zenoss Community member David Nicklay for sharing his new HP Blade Chassis ZenPack.  This ZenPack provides monitoring for HP Blade Chassis (not to be  confused with Compaq servers) via SNMP executed by a Perl script.  The  device class /Devices/HPBladeChassis provides a BladeServer template.  There is also a bladeserverlist report  available.

Thanks David!
