Updated VPLEX HA KB article (re vSphere 4.1)

FYI – the VPLEX team and the vSphere team have updated the VMware KB article that refers to VPLEX behavior in stretched vSphere cluster use cases to include vSphere 4.1

To recap – this use case (formalized test harness for stretched vSphere clusters) is a relatively new thing.   Unlike the formal VMware HCL process for storage devices, which is mature, this is an area where VMware and the storage vendors that support this sort of thing are treading on new ground (i.e. formal testing the myriad of failure cases).

We published this back with vSphere 4.0 support, and just finished the explicit vSphere 4.1 testing work, and VMware just finished reviewing the results.

You can check it out here.

BTW – Host Affinity is not noted, not because it wouldn’t work in this use case – but because that test harness is not finalized, and all the various implications (in various partition behaviors at the VPLEX and vSphere layers) isn’t quantified.

don't know who created that diagram... but maybe use Visio instead of Windows 3.11 MS Paint :-D

any idea when DRS host affinity will be supported/quantified? would have thought it would have improved VPLEX setup by using soft rules to keep VMs in the correct site unless moved manually, or by HA following an outage?
