Thank you Jeff.  Consider that if rack space is at a premium, what would make the most sense?

IF you bought a server with that topology, you would definitely want to run lots of instances, perhaps 24, to effectively utilize that disk space.

You'd also need 24 IPs, and you'd need a NIC that could send/receive 24x the normal bandwidth. And the cost of rebuilding such a node would be 24x higher than normal (so consider how many of those you'd have in a cluster, and how often they'd fail).

    Dell has machines with 24, 8TByte drives in a 2u configuration. Given
    Cassandra's limitations (?) to large nodes, would it make sense to
    run
    24 copies of Cassandra on that one node (one per drive)?
    Thank you!
