Hi dear Donald, thank you so much for answering.

My PS does not have any port configured, insted of I use IP address to get access.

When I try to open:

http://MANAGEMENT_IP/welcome.html 

and then just triying with the IP address I got the following message:

But run the Java Applet as an application option  is not showing up, I used ie, firefox, chrome, getting the same thing.

My storage space is running out and I must to do an increase of it. is there another option to do that?

Kind Regards.

this is the data:

ESXi 5.5 version

EQL 3.5.3.10 version

I got 8 datastores 1 Tb each one, two of them there is something like a 400 Gb of free space to assing it to datastore, I don't why the former administrator did it in that way, that's the reason why  I'm triying to open PS group.
