i would not worry as much about the single machine specs. find the
sweet spot on price for CPU and RAM and by that, then scale horizontal
to meet your demand.
but .. if i was pressed for a general statement -choose RAM over CPU

It seems you RAM/core ratio is different between your options.
So if those two are your only options I'd suggest the 16GB option.
Still, the other things
* Concurrency
* Fit in ram
* IO
Are very relevant.

Also, take into account i/o since they are often a limiting factor.

+1 - I've seen our 8-core boxes limited by RAM and inter-rack
networking, but not by CPU (yet).

Hi,
Sure it depends... but IMHO 6 GB is suboptimal for big data because it means
1,5 GB or 2 GB for Cassandra.
Maybe you could elaborate your use case. You really want a one node cluster ?
cheers,
Romain

Hi, Hagos,
I think it depends on your business case. Big RAM reduce latency and
improve responsibility, High number of cores increase concurrency of your
app. thanks.

Hi All,
For of my projects I want to buy a machine to host Casssandra database.
The options I am offered are machines with 16GB RAM with Quad-Core processor
and 6GB RAM with Hexa-Core processor.
Which one do you recommend, big RAM or high number of cores?
greetings
Ambes
