High-Velocity Elasticsearch Cluster Setup

Few Requirements:  
Ingestion capacity: 1TB per day  
Retention: 7 days  
Events: 100000 events per second per day

How many nodes (master/data/ingestion/co-rdinating) required?  
How much RAM and Heap required?  
How much Disk Space required?  
Do I need to change thread pool sizes?  
Any other performance tuning for high search and write?
