When scanning our hosts for vulnerabilities, I found that TCP port 8045 on the ESXi host showed up as running IBM DB2, I do not think this is the case, but I am not sure what all happens with HA.  Can anyone shed some insight on this?

8042 to 8045 TCP is used by VMware HA, not IBM DB2.

See TCP/UDP ports in use

Distributed Resource Scheduler (DRS)). Automate the optimal placement of virtual machines restarted after server failure.

Can I choose what host a guest goes to?

You can define Affinity rules, to stick VMs to hosts, but that's not really the idea behind DRS, because it best selects the host.

What does triggers an HA event?  Just the lost of network connsctivity between vCenter and the host, or would a power supply failure on a host with dual supplies cause an HA event?

Host failure, which could be hardware fault on the host, or loss of networking to the Host.

A single power supply failure, with two power supplies, does not cause the host to fail!
