Very nice!!! In my environment I did it:
I have a group, named Blocked with about 1000 clients in differents subnets, ok.
So, I created a Multiple GUP policy, using 2 clients as GUP from each Subnet, I have a big list of clients, because I have many subnets!!!. If one GUP goes down, I have another, because of it, 2 per subnet.
I understant that SEP client searchs for GUP in your subnet and use it. In the policy I configured if GUP does not work after 50 minutes, client can use the Manager to download.
So, if the GUP is off, or I dont have a GUP for that subnet, client can goes to Manager. It is working great for me. I have around 99.80% of online clients up to date. But I need to take care with the bandwidth, because all clients from a subnet without GUP can goes to Manager and download big files :)
Please, fix me if Im wrong. In Explicit GUP, if that client does not have a GUP in its subnet, it searchs for a GUP near its, and download it, right?
Thanks,
Diego
