We are thinking of performing our upgrade from ESX 3.5 to vSphere with ESXi.
Our environment is 25-35 hosts, mostly HP and some Dell.
What should we be cautious of with ESXi (besides not having a console and any scripts, etc)? Limitations?
I think it will take a bit to get used to vCLI and vMA since we have been used to the console on the host since ESX 2.0. I had heard some issues with security related to ESXi, but I don't recall where I heard that, does anyone have any information that might be useful?
Besides the ESXi Chronicles Blog, does anyone have any good blogs, etc to recommend specifically for ESXi?
BTW- Are they going to change the name to vSpherei?
I think SSL/SSH is secure enough.

It's not an ESXi-only tool but many ESXi users have found PowerCLI helpful for installing and configuring ESXi hosts and their VMs.

If you're going to run FT machines - do not mix ESX and ESXi in the same cluster.

I have not really big infrastructure - about 10 hosts with 100+ VMs, but I see a very little need for ESX console. And since we're going to upgrade this year mabe up to 30-40 hosts I see even less need for ESX console. It can be useful sometimes, but only for troubleshooting.

ESXi is more secure than ESX.

Any vmware related blog contains a lot of information about ESXi, it's just a part of big family. There is nothing so special in service console, ESXi can do anything ESX can.

Many pluses. When you have a couple of hosts and 20-30 VMs it's not hard to do all the tasks manually, in vSphere client. But when your infrastructure starts to grow PowerCLI becomes very useful.

Perhaps the security question was related to the traffic between the vCLI or vMA and the hosts..?
I think SSL/SSH is secure enough.
