Hi all, In our small company we have 10 nodes of (2 x 3 TB HD) 6 TB each, 128 GB ram and 64 cores and we are thinking to use them as Cassandra nodes. From what I am reading around, the community recommends that every node should not keep more than 1 TB data so in this case I am wondering if it is possible to install 2 instances per node using docker so each docker instance can write to its own physical disk and utilise more efficiently the rest hardware (CPU & RAM).
I understand with this setup there is the danger of creating a single point of failure for 2 Cassandra nodes but except that do you think that is a possible setup to start with the cluster? Except the docker solution do you recommend any other way to split the physical node to 2 instances? (VMWare? or even maybe 2 separate installations of Cassandra? ) Eventually we are aiming in a cluster consisted of 2 DCs with 10 nodes each (5 baremetal nodes with 2 Cassandra instances) Probably later when we will start introducing more nodes to the cluster we can decommissioning the "double-instaned" ones and aim for a more homogeneous solution.. Thank you, Wil
