Difference in the last two digits is probably because on ESX you're seeing the World Wide Port Name, while on the switch you're looking at the World Wide Node Name.
One is the ID for the adapter, the other one for the port.
If you expand the WWN entry on the switch, you'll probably see the WWPN as a subitem of the WWN (you can do zoning on either of them)
check your storage adapters under the configuration tab, there you will see the WWN numbers of the installed adapters.
Like Troy said they're under the storage adapters under the configuration tab. See attached screenshot

Thank you guys. However, I am scared because when I check the "storage adpater" configuration, I have something like this:
vmhba1: .... 50:01:43:80:00:ac:d9:18
vmhba2: .... 50:01:43:80:00:ac:d9:1a
Now, there weird thing is, when I check one of my SAN switchs, I have this:
50:01:43:80:00:ac:d9:1b
and on another switch I have:
50:01:43:80:00:ac:d9:19
see the difference on the last two digits? Why they don't exactly match?
two different HBA's, they should have unique WWN's or something is wrong.

...I just noticed the difference in WWN number reporting to the SAN. I'm not a storage guy, but the WWN numbers from your HBA's should be the same on the SAN as the HBA.
Troy, as you see, they are UNIQUE by the last two digits. My quesiton is the last two digits don't match those on the switches.
My ESX connects to 2 switches (one HBA each switch so I have redandency here.) My ESX works just fine. Thanks for your quick reply.
I just noticed the second part and updated my post. I'm not a SAN guy but when I give my SAN guy the WWN numbers of our HBA's they match on the SAN. I'm not 100% sure what's going on.

Thank you patrickds for coming to the rescue as I madly search the Forums for the correct answer
It doesn't hurt to double check the switch port that that you know you are plugged into either.

What you have is a dual port fibre channel adapter. The last octet is unique between each physical port with a last octet of 18 and 1a. The next two WWNs are node IDs and are incremented by one,, so you get 19 and 1b.
