We will be deploying an HA (high-availability) ready structure of ALM 11.50.
This mean that there will be 3 servers
1. Application server
I cannot find in any documentation information for systemrequirements for the repository and database servers (hardware specs)
Can you suggest?
We are planning to allocate 8gb RAM for Repository and DB servers and 16gb RAM for the Application server.
Do you think this is enough?

To give any proposal on hardware specs, there has to be more data about current production system and projected growth.
You should estimate the number of defects, tests, runs, requirements etc. and their change over time to plan for the new deployment.
If you want to have HA environment, you should deploy at least 2 app servers - both pointing to the same repository. You may also want to empoy HA on database level if you see performance impact on SQL in your current production.
I think it would be a good idea to work with HP Professional Services or HP Partner on all aspects of proper deployment.
Hope this helps.

Even HP Professional Suppport ahven't given us a concrete answer.
Anyway, I sense you are familiar with HA.
Does the structure really needs a load balancer?
or HA structure can function without it?
We only have at most 20 concurrent users, the point of the HA for our business is just to have a backup app server running in case one server goes down.
for your advise.

HA (High Availability) is a concept. It’s the ability of QC have to have several QC application servers on a cluster, so in case you have to troubleshoot 1 of the clusters, the other app server can take over and continue to work without scheduling a server down.
So if you are planning to use dual nodes(clusters),then obviously its better to have a load balancer,thats when your intention will serve the need and if one node goes down in the cluster LB will route traffic to other node so the app keeps running.If no load balancer and you are planning to use individual node urls,then it doesn't make sense to have dual nodes.
