Hi, The hardware you choose depends a bit on your workload - writes vs reads, amount of cacheable data, latency requirements, etc.. What sort of workload do you expect?
See http://wiki.apache.org/cassandra/CassandraHardware for some general advice. People typically have 8-24 GB RAM per node with 1-8 TB of storage, but there are cases where bigger or smaller makes sense. Don't overspec your nodes - you'll be better off with more smaller nodes. You can use SSDs if you need the random read rate, and SATA drives are fine too. -- Richard Low Acunu | http://www.acunu.com | @acunu On Mon, Aug 29, 2011 at 2:15 PM, Helder Oliveira <helder.olive...@byside.com> wrote: > Hello guys, > > What is the type of profile of a cassandra server. > Are SSD an option ? > Does cassandra needs better CPU ou lots of memory ? > Are SATA II disks ok ? > > I am making some tests, and i started evaluating the possible hardware. > > If someone already has conclusions about it, please share :D > > Thanks a lot. >
