1-1. Power use and heat dissipation increase exponentially with frequency (left), so after 2004, processor vendors began limiting the frequency (right) and increasing the number of cores per chip. What determines the number of CPU cores offered in HP ProLiant servers? HP ProLiant servers include - HP ProLiant DL288 | ISS Technology Update, Volume 7, Number 8 - Page 3
trend to increase the number of cores per chip is irreversible because single-core CPUs use more power to achieve the performance levels HP BladeSystem ProLiant server blades and ProLiant servers" technology brief URL http://h20000.www2.hp.com/bc/docs/support/SupportManual/c 01518167/c01518167.pdf - HP ProLiant DL288 | ISS Technology Update, Volume 7, Number 8 - Page 4

If the server is on, the "stop system1" command issues a virtual power button press. This event is normally intercepted by the OS ACPI support to initiate a graceful shutdown.

Frequently asked questions about HP UPS Management Module
Newsletter staff recently received questions from the field regarding a previous newsletter article on HP UPS Management
Module (HPMM) (refer to ISS Technology Update Volume 6, Number 8). Since other customers may be experiencing the same
issues, this brief article will present those questions.
HP technical staff has provided the answers.
FAQs
Question #1________________________________________________________________________________
Q.
Is there a version of the HP UPS Management Agent available for customers running operating system ESX 3.0.x that will
provide an automatic shutdown solution when the uninterruptible power supply (UPS) runs out of power? We found
compatibility information online for VMware 2.5.x, but not specifically for 3.0.x.
A.
Technically, the current HPMM Power Protection Agent should work with VMware 2.5.x or ESX 3.0.x. The only difference is
that for ESX 3.0.x there is a shutdown option. If this option is not set correctly, when the server is rebooted, the user will
receive an error message at the login screen because the server was not shut down gracefully.
Question #2________________________________________________________________________________
Q.
From where can the agent be downloaded, either internally or externally?
We can find Windows, HP-UX, and Linux
versions online externally, but none for ESX (even version 2.5.4).
A.
VMware is based on Linux; the Linux agent is available for download at
