Hi Brandt,
The reason was based on the fact that HA now uses shared storage to help determine when a host is down or has just become network isolated. If the IP based storage is using the same northbound switches for regular network connectivity, then if host becomes network isolated, this extra check won’t help.
It used to be part of VMware’s Availability Guide.
However I’ve just noticed an update to this guide that states:
Removed note that recommended the user disable datastore heartbeating in a “converged” network environment. This is not a best practice and could lead to logical network failures. See “Datastore Heartbeating,” on page 16.
Interesting that this advice has now changed. I’ll update the card sometime soon to have this removed.
Forbes

I have been using your site for a few years and it is one of the best. Keep up the great work.

I have more of a technical question that hopefully someone can point me in the right direction.

Under the Availabilty section (HA), there is a comment “Disable datastore heartbeating if using Ethernet based storeage”. I have been trying to find the why but cannot find any document that explains. Can someone point me in the right direction?

Thanks
