1) How can I tell what version of ESXi I am running right now? I installed 3 update 3, but when looking into some other questions, I ran the update in VI. Am I now at update 4?
2) Firewall - I've found some things that indicate that there is a firewall, or there may be a firewall, or there is no firewall. Does ESXi 3 have a firewall? If so, where is the docs for it? I need to know because...
3) SNMP - Again, some sources say there is no SNMP, some say there is, some indicate there's something like SNMP that isn't really SNMP. I want to monitor my ESXi server with cacti. What is needed to make that work?
4) Dell OMSA - And again... some things say I can run this, some say I can't, some say I have to use a customized version, some say OMSA is built in to update 4 (which is why I did the update mentioned above). What's the real story? How do I get OMSA working on my server?
5) Updating - If I do have to install a customized version of ESXi to get OMSA ( I have an ISO called "VMware-VMvisor-InstallerCD-35_Update_4-153875-i386_DELLCustomized-Ext" ), is there a way to make it leave my datastore alone? Or is there absolutely no choice but to move the VMs off, install, and then move them back on again? All storage is DAS right now... no SAN (yet).
