[UPDATED – 11/7/2011, 1:39pm] – updated to fix broken link, and updated for Copenhagen content that also refers to new vSphere Metro Stretched Cluster (which you can read about here: New VMware HCL category- vSphere Metro Stretched Cluster), and also embedded a recording of the session in Copenhagen.
Presented by Lee Dilworth (“Mr. SRM” at VMware – though forgets more about non-SRM disaster avoidance and disaster recovery in a day than most humans learn in a lifetime :-) and I. The purpose of this session was to cover the state of the art when it comes to SRM and stretched clusters. This is a topic that Lee and I (and Scott Lowe too) get hit with over, and over… and over. The key is that for now there are a set of “mutually exclusive design decisions”, and people tend to “mash things up” in their minds as these are related ideas.
Think of the set of “disaster avoidance” and “disaster recovery” solutions as a Venn diagram – overlapping, but not the same.
The session was very popular – each time having about as many people there as the EMC super session (which had more attendees than all the other supersessions – though they were all lightly attended IMO), and was repeated twice – with the second one being recorded (available for VMworld attendees). It will also be presented at VMworld 2011 in Copenhagen if you are there.
HINT: BTW – stay tuned in this space. There is another shoe that will drop that was not quite ready in time for VMworld – if you were in the session, or watch the recording, you might see Lee and I tapdance around it a little bit.
Read on for the session feedback and content!

Chad,
Links no worky! :) Help.

Hi Chad,
I had a few questions regarding the improvements that vSphere 5 provides with a stretched HA cluster using VPLEX as follows:
1. All the KB articles and best practices documents still refer to vSphere 4.1 - when will they be updated for vSphere 5.0?
2. What stretched HA cluster sizes will be supported in vSphere 5 (i.e. will it be bigger than the current 8)?
3. With vSphere 5 and VPLEX 5 are there any remaining limitations with stretched VMware HA clusters (clearly in the past you have not recommended this solution and I believe there were scenarios where HA restart would fail - you refer to the VM being in an indeterminate state when the storage is removed)?
4. Are there any plans for VMware to support round-robin multi-pathing with VPLEX?
5. What are the plans for VPLEX to support vCenter SRM and do we really need it - it would add considerable cost?
6. What are the timescales for VSI based VPLEX provisioning?
7. What are the plans to have a VPLEX GUI process (i.e. VSI) that will provide disaster avoidance and vMotion all VMs to the other site using DRS to balance the load - this would also need to change the preferred VPLEX site for the LUN?
8. What are the timescales for VPLEX to support VAAI?
Many thanks
Mark

Hey Chad,
This preso link isn't working either. Can you please post again?
Thanks,
