Are you using DPM? We need you!

Duncan Epping · Jul 7, 2010 ·

I just received a request from our Product Management team. Gil Adato is is working on the next generation of DPM and is seeking DPM current and past users and he asked me to post the following message on my blog. I hope you can help Gil and VMware taking DPM to the next level!

Dear VMware Customers,

Product management is starting planning efforts for the 2012 vSphere release, and we are considering numerous DPM improvements. In order to make the right decision, it’s critical that we get a better understanding of our customers’ experiences with the current product, and get customers’ feedback on what needs to be on the roadmap. We’re also interested in customers’ improvement suggestions and in sharing with them several improvement ideas that we have in mind. Customers’ input will be very helpful to us, and customers would see the benefit of communicating their comments, requirements and suggestions/wish-list directly to the product team.

If you’re a current or past DPM user and you’d like to be a part of the process and help shape the next generation of VMware’s products, please contact me directly.

My contact info is the following:

Gil Adato
gadato@vmware.com

When contacting me, please send me the following initial information:

  • Company Name
  • Customer contact name
  • Location (Country)
  • Customer’s email address

VMware’s product management team is looking forward to hearing from you and making you a part of the product development process.

Thank you for your cooperation,

Gil Adato

HA Admission Control and DPM

Duncan Epping · Aug 20, 2009 ·

A couple of days ago we had a discussion on Admission Control and DPM internally at VMware. One of our customers had enabled DPM on a HA cluster. During the evening 4 out of 5 hosts where placed into standby mode because of this.

This customer, as many of our customers have these days, had vCenter running virtual. This of course led to the question; what happens if this one host fails and our virtual vCenter server is running on it?
That’s an easy one; nothing. It might not be the answer you are looking for but when the host fails that runs vCenter there’s no host or service left to get these hosts out of maintenance mode or restart your VMs.

Now maybe even more important; what causes this behavior?
This behavior is caused by the fact that admission control is disabled. If you disable admission control DPM will put hosts into standby mode even if it violates failover requirements. This means that if you have virtualized your vCenter server this is definitely something to be aware of.
