As an active moderator and VMware Communities Guru, I’m in a unique position to see the level of vSphere adoption from an interesting vantage point — topic activity in the forums.
Take one morning’s statistics from this past week:
- 3 pages of new VMware vSphere Forum Posts vs 1.5 pages of VMware ESX 3.5 Forum Posts.
- VMware ESX 3.5 Forum posts used to be around 3 pages
- The majority of VMware vSphere Forum Posts that dealt with ESX 4 vs ESXi 4 was in favor of ESXi 4 by a wide margin (I did not actually count posts but noticed there were more ESXi posts than ESX posts in those 3 pages)
So using this as a rough measurement and in a completely unscientific way, we do see that VMware vSphere is being investigated for use at least by those activie within the VMware community forums. The same thing happened when ESX v3.5 was released, and over time ESX 3.0 community posts dropped to less than a dozen per day. (I say per day because I review the vSphere, ESX 3.5, and ESX 3.0 communities once about every 24 hours give or take an hour or so.)
Given the types of questions, it looks like two things are happening:
- VMware vSphere is being investigated
- VMware ESXi 4 is the packaging of choice
The second item could be because many people believe that when the next version of ESX comes out, it won’t have a service console, and these users want to get a head start on the adjustment.
What we do not know from this type of adoption measurement is whether these are adoptions for use within production, enthusiasts, or testing within lab environments.
What we do know is that the increase in volume and the drop in ESX v3.5 forum posts is that vSphere is definitely gaining traction. This is not surprising, but what is to me is that ESXi 4 has a constant flow of posts while ESX 4 does not. This will shift the security model people employ to protect virtualization hosts as well.
