Eaton UPS Safely Protects Systems with Graceful Shutdown
Eaton
Intelligent Power Protector joins the UPS makers management suite to
extend graceful shutdown of physical host systems including those
hosting VMware virtual machines.
Intelligent Power Protector (IPP) started shipping on Oct. 4 and is
available as part of a free download for up to 10 IP addresses. When IPP
is combined with Eaton's Intelligent Power Manager and an Eaton plug-in
for VMware vCenter 4, the combined package is a suite of tools that
neatly handled the graceful shutdown of affected systems before the UPS
battery power ran out. But only if your organization uses Eaton UPS
hardware with specific controller cards.
IT
managers who are accustomed to Eaton's mass configuration and
management tool called IPM (Intelligent Power Manager) will have little
trouble using IPP. IPP has every appearance of being built from modules
pulled out of IPM to such an extent that the two products, although
available as a suite, cannot be run on the same system. IT managers who
used Eaton's Netwatch product should also have no trouble implementing
the graceful shutdown policies provided in IPP.
I
tested IPP using an Eaton UPS 9130 that provided conditioned power and
battery back up for an HP DL360 G6 and an HP DL380 G6. The HP systems
are part of the physical host infrastructure of the VMware vSphere 4
test environment at eWEEK Labs. I installed IPP on a Windows system on
the same subnet as the HP servers. I also installed Eaton's management
software along with a plug-in for vCenter 4 on the vCenter server. All
instances of IPP and IPM used discovery tools to scan the network and
find in the Eaton 9130.
IT
administrators will need to plan for system security when using Eaton's
IPP and IPM applications to control management costs. To access power
sources--Eaton's term for UPS systems equipped with specific interface
cards that provide management features--login/password credentials are
usually required. While it is possible to change these credentials using
management tools from Eaton there is a bit of variety between the UPS
management cards such that passwords are sometimes advised and sometimes
mandatory. Keeping track of machine and user credentials will be a
non-trivial task for IT managers who are widely install Eaton UPS
systems.
IPP
controls local computer shutdown scenarios using timers that control
duration and shutdown type, such as hibernation. There is enough
flexibility in the shutdown configuration policy module to handle nearly
every contingency. I set up policies to prioritize the DL380, which is
the ESX host that runs most of the core infrastructure VMs including our
lab domain controller and DNS server over the DL360. Systems can be put
into hibernation mode, shutdown entirely or controlled with a shutdown
script to perform custom actions. The shutdown module also controls the
outlet action so that I was able to turn the outlet off after a power
event or leave it active so that connected systems would come back on
when utility power was restored.
