Introduction - Dell PowerEdge UPS 500T User Manual

1. INTRODUCTION

Dell is a world first class supplier of hardware and software to optimize business continuity on
VMware virtual platforms. It means controlling proper boot and shutdown of the virtual machines
hosted on a same physical machine, assuring data integrity on each virtual machine.
Dell UPS Local Node Manager is a solution to automate various data security functions. Dell ULNM
provides following features:

Continuously waits for information from the Dell Management Card (H910P) connected to
the DELL UPS.

Warns administrators and users if AC power fails

Proceeds system shutdown before the end of battery backup power is reached.

Restarts machines when AC power restarts.
VMware ESXi does not have administrative console and hence we cannot install Dell UPS Local Node
Manager (Dell ULNM) on that machine. However, we can install Dell ULNM on VMware
Infrastructure Management Assistant VIMA 1.0, or on vSphere Management Assistant (vMA 4.0).
Using that, we can manage and shutdown the VMware ESXi in case of UPS and power anomalies.
We can also configure ESXi to safely suspend or shutdown guest operating system. This way we can
have only one Dell ULNM shutdown agent on only one guest operating system (VIMA, vMA).
There are various benefits to install Dell ULNM client on the VIMA, vMA instead of each Virtual
Machine:

Only one binary of Dell ULNM client on the VIMA/ vMA to manage all Virtual Machines.

Dynamic management of virtual machines configuration with a personalized script.
This guide will help to install and configure Dell ULNM client on VIMA, vMA.
Dell ULNM client is tested on VMware virtualization server with two guest operating systems
(Windows Server 2003 R2 & Red Hat 5.4) for electrical power events, shutdown, low battery and
reboot.
Dell tested virtualization security in a standalone power supply configuration, for system shutdown,
electrical shutdown, and reboot.
