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
