PernixPro member update – The new class

Today I would like to announce the second class of PernixPros. Enriching the first group of PernixPros. It was a tough process to go through all of the amazing submissions and select the best candidates. If you weren’t selected there is no need to reapply. Your best bet is to keep doing what you have been doing in evangelising PernixData and supporting the virtualization community.

Quick overview of the PernixPro Program
At PernixData we believe in the power of the community and one of the pillars of this program is to provide members early access to the beta product that allows them to chime in and give feedback to the engineers and product team. Luigi Danakos posted an interview with Jane Rimmmer about the PernixPro program recently…Six Questions on the PernixData – PernixPro program

We will be contacting all our new PernixPro members to set-up an overview of the program and kick off the great discussions around PernixData FVP. For those that didn’t make it this time keep following us on Twitter @PernixData for updates.

Which HA admission control policy do you use?

Yesterday Duncan and I where discussing the 5.5 update of the vSphere clustering deepdive book and we were debating which HA admission control policy is the most popular. Last week I asked around on twitter, but hopefully a short poll will give us better insights. Please cast your vote.

Gotcha – Disable reserve all guest memory setting does not remove the reservation

A while ago I wrote about the nice feature Reserve all guest memory available in vSphere 5.1 and 5.5. The feature automatically adjusts the memory reservation when the memory configuration changes. Increase the memory size and the memory reservation is automatically increased as well. Reduce the memory size of a virtual machine, and the reservation is immediately reduced.

Setting enabled

This week I received an email from someone who used the settings temporarily and when disabling this setting he was surprised that the reservation was not set to 0, reverting back to the default.

Although I understand his point of view, the reality is that when you enabled the feature your intent was to apply a memory reservation to the virtual machine. The primary function of this setting is to take away the responsibility of adjusting the reservation when you change the memory reservation.

If your goal is to remove the memory reservation, disable the setting Reserve all guest memory and then change the memory reservation to 0.

Enhance, Enhance, Enhance – FVP 1.5 Performance graphs

Enhance, Enhance, Enhance a line that makes techies smile or cringe when used in movies and TV series. CSI was (Is it still airing?) notoriously famous for it. The agents of NTSF:SD:SUV took it a step further.

All kidding aside you sometimes need the ability to zoom in to the smallest detail in order to get a better understanding of the situation or performance in our case.

The new FVP 1.5 software helps you with that and the U.I improvements are awesome. One of the UI features I love is the zoom view. When reviewing the performance graphs, terrible performance of the datastore can skew the performance view. While the performance of the flash device is in the sub millisecond range, having a datastore performing at 350 ms latency will bias the graph and basically render the important metric VM observed latency invisible.

Enhance-01

Zoom in functionality allows you to dive into the details. Just hover over the area that you want to investigate, hold the mouse button and drag the area of interest. The graph will zoom in.

Enhance-02

You can get an accurate readout of metrics by hovering over the data point, or if you like zoom in a little more. Just repeat the previous action, hold the mouse button and drag the area of interest.

Enhance-03n

It up to you how much detail you want. Now the only thing I ask, is not to sit behind your screen and yell enhance, enhance, enhance every time you do this. ;)

April U.S. Roadshow
