ULNM with Xen Virtualized Architecture
The Dell UPS Local Node Manager (ULNM) discovers and supervises Dell UPSs and PDUs connected
across a network, either by means of a card or proxy. It supervises the remote servers hosting the Dell
ULNM and also provides local computer graceful shutdown. The Dell ULNM interface can be accessed
remotely using a Web browser. Our objective is to provide virtualization support for Dell ULNM power
protection software.
The Xen virtualized architecture includes the following:
Citrix XenServer 5.6
OpenSource Xen 2.6 on RHEL 5
OpenSource Xen 3.2 on Debian 5.0 (Lenny)
Figure 95 also illustrates two solutions for Citrix Xen:
The first solution provides graceful shutdown for Citrix Xen. The Dell ULNM is installed on each
Citrix Xen system and does not require XenCenter management software
The second solution serves multiple Xen servers and provides the following features:
Xen server remote maintenance to trigger VM XenMotion
Xen server remote shutdown (with the Dell ULNM)
This solution is ideal for biggest infrastructures working through XenCenter
