Hi,

What about this type of blades, which gives you about 12 (commodity) servers  
in 3U:

Thank you Max.  That is a solid choice.  You can even configure
      each blade with two 15TBytes SSDs (may not be wise), but that
      would yield ~430TBytes of SSD across 14 nodes in 4u space for
      around $150k.

Have you considered a blade chassis?  Then you can get most of the
      redundancy of having lots of small nodes in few(er) rack units. 

SuperMicro has a chassis that can accommodate 14
        servers in 4U:

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).

We have a
                        large amount of data to be stored in Cassandra,
                        and if we were 
 to purchase new hardware in limited space, what
                        would make the most sense?
 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!
