we building cassandra (2.1.5) cluster storing large amount of timeseries data, , planning utilize existing hardware, problem hardware available different.

2 machines with: 4 core, 8 gb, ssd
2 machines with: 8 core, 16 gb, ssd
2 machines with: 32 core, 64 gb, hdd

obviously, 32 core machine can handle larger load 4 core machines, how should configure cassandra handle this. using rf 3 , latest datastax java driver.

any suggestions?

when configure cassandra node tell number of vnodes use node. load on node proprtional number of vnodes. hence choosing different numbers of vnodes computers can distribute load unevenly among them.
