I have an older HP R3000 XR battery backup. Does anyone have any idea if there is a plugin for ESXi free? I don't have a network management card - only a serial connection. Otherwise I'm assuming I can install the battery backup software on one of my server VMs. Thanks!
I would say you could passthrough the serial connection and call it a day but I like having the mgmt cards if its something you can get your hands on, its always good to have multiple access points in the event *something* happens to one of them.
The bottom line is that you MUST have a networked management card for your battery backup in order for ESXi to communicate with it via a plugin. Or can ESXi talk to it via the serial port?
Im not sure about it being able to communicate directly on serial via plugin for esxi but im not seeing any google results for it so i assume if you want it to talk directly to esxi youd have to do it through the network card/snmp monitoring.
