We are in process of designing network for Hadoop cluster and looking for best practices around it.
Following are few scenarios where we seeks your expertise.
1. Dedicated VLAN Vs Flat VLAN - i.e. separate VLAN for Data ingestion, node connection and replication Vs one VLAN for data injection and replication
2. Factors which decides cable selection (1Gig/10Gig) across different network layers
3. Use of Firewall in L2 network
I look forward to your advice and pointers
