Hi, I’m not a Cassandra expert but according this reference : http://docs.datastax.com/en/landing_page/doc/landing_page/planning/planningHardware.html#planningHardware__capacity-per-node You already reached (even exceeded) the recommended limit for HDD.
As usual, I guess the maximum limits depend of your use case, data model and workload… Regards, Eric De : Shalom Sagges [mailto:shal...@liveperson.com] Envoyé : jeudi 24 novembre 2016 14:48 À : user@cassandra.apache.org Objet : Max Capacity per Node Hi Everyone, I have a 24 node cluster (12 in each DC) with a capacity of 3.3 TB per node for the data directory. I'd like to increase the capacity per node. Can anyone tell what is the maximum recommended capacity a node can use? The disks we use are HDD, not SSD. Thanks!
