I am pretty new to this and I really appereciate if anyone can help me on this.
I have a powerconnect-w3400 on site 1 and couple of aruba 105s on my site 2, on different subnets. I want my APs to see the controller on site one. and I also have a local DHCP server on site 2.
could anyone tell me what whould be the best to do to connect APs to controller?

There are 3 ways in which an AP discovers the controller
1. DHCP - option 43
2. ADP - requires layer2 connectivity
3. DNS query for "aruba-master"
Since, the AP and controller are not on the same VLAN, you can use option1 or option3 for the APs to discover the master controller IP address.
Option1: You need to configure the Option 43 on the DHCP server to the controller IP address
Option3: You need to configure an A record on your DNS server for "aruba-master" that resolves to the controller IP address
Hope it helps.

Thank you so much for your answer,
Can you tell me how am i going to do these, first for DHCP option43, what whould be the vendor class ID and the sub_option code and is the IP the IP of my controller? Can you please tell me a step by step on how to do option 43 and what needs to be done on my controller and Ap?
and as for DNS, i just need to creat that record and I am good to go?

By default, all controllers come up as a standalone master controller.
It would be very useful to read the campus VRD to understand the working of Aruba controllers and APs.
