Hi guys! just your opinion:

i am planning on buying two HP server machines as primary and secondary DC with storage role for around 30 users. What would you advise in terms of hardware setup, redundancy and performance?

Assuming that you are not still running NT (in whch case why is this post in the 2012 forum?) there are no such things as primary and secondary DCs. Exactly what advice do you need? You just set up both machines as DCs.

Hardware-wise, i would use RAID-5 and have dual PSUs and NICs in each server, teaming the NICs for redundancy. But with dual DCs you don't really need to worry so much about hardware redundancy.

Thank you for your feedback ijack! By secondary DC i meant a read-only machine to handle user authentication on the network in case the main DC goes down.

What would you advise for high information availability? For example, the same folder structure and files for the users on both DC machines synced and updated between the two DCs possibly through DFS so when one of the two machines goes down users on the network are still able to access their mapped network shares...

Thank you.

DFS is nice if you feel it's neccessary. That is really your call in the end. Just keep in mind using file replication will add quite a bit of network overhead and is probably best kept on its own VLAN. As far as RODC's go, I would not bother unless it's in a remote office with no on site admin to manage it, or if the server can't be secured physically.

Both DC's should be global catalog holders as well as dns servers. If doing dfs you should also consider doing split scope dhcp on both DCs
