Subject RE: [PROPOSAL] Raise cluster size limit to 16 on VMware
Date Thu, 20 Dec 2012 16:36:10 GMT
As we are discussing the "cluster" limit, would be more appropriate to set this as a cluster
property - since I dont anticipate mixed clusters (such as a single cluster having VMware
4.x and 5.x), it would cover  Dave Nalley's concern? 

One still still might be - if a single cluster has multiple primary storages, how do we address
this - VMFS might have limit X, NFS might have limit Y but belong to the same cluster - least
common denominator?

Hi,

I'd recommend removing any hard limits from CS and introduce a variable like "max.guest.limit"
on the Hypervisor Capabilities page.
This value could default to 8, but should the admin decide otherwise could be set to anything.

Regards

that the max. can be 32 for ESX 5.1. Any specific reason to make it 16? Also it needs to be
seen that this limit works across all supported ESX versions.

Yes - the different versions having different limits complicates things a bit.
5.1 = 32, 5.0 = 16 4.x = 8?
