63% not utilizing Resource Pools

November 2nd, 2008

A one month long Virtual Infrastructure poll wrapped up over on the VMware VMTN Community forums and produced some intuitive findings. The poll results reflect that the majority of respondents are not using or not effectively utilizing VMware Resource Pools. Myself included. To tell the truth, I have the resource pools set up (shares configured only, no reservations or limits), but we’re not pushing the virtual infrastructure hard enough for them to provide the benefit they were designed to deliver which is guaranteed resource allocation and resource allocation weighting in a heavily used infrastructure where there is resource contention.

What does this mean? In my case, and I’ll go out on a limb and suspect much of the same is true in other environments, the virtual infrastructure isn’t filled to the capacity that it was designed to handle. More virtualization is needed.

ESX configuration script – display full path in COS

October 25th, 2008

MS-DOS old timers should appreciate this. I’ve been using this snippet for a few years in my ESX host deployment scripts.

ESX script to display the full path in COS

Example:

In your ESX console, instead of seeing this:

[root@host vmware]#

You’ll see this:

[root@host /etc/vmware]#

#Paste the following into PuTTY on your ESX host:

mv /etc/bashrc /etc/bashrc.old

sed -e “s/\\h \\\W/\\h \\\w/g” /etc/bashrc.old > /etc/bashrc

Close your PuTTY session and re-open to see the change take effect.
