Especially in light of replication (broker-broker communication), I'm 
wondering if all the brokers are in the same rack and what kind of 
networking interfaces are used (Gigabit ethernet, Fibre Channel, etc).

Thanks Jun. Couple more questions: 
1. Do you guys have dedicated hardware for Zookeeper or do you have a few 
machines run both a ZK and a broker? If so, do you keep the ZK and Kafka data 
on separate volumes?
2. You use the 14 drive raid setup is just for Kafka data and a separate drive 
for the OS?

It's more or less the same. Our new server has 14 sata disks, each of 1 TB.
The disk also has better write latency due to larger write cache.
