Cassandra on high performance machine: virtualization vs Docker

2018-02-27 Thread onmstester onmstester
What i've got to set up my Apache Cassandra cluster are some Servers with 20 Core cpu * 2 Threads and 128 GB ram and 8 * 2TB disk. Just read all over the web: Do not use big nodes for your cluster, i'm convinced to run multiple nodes on a single physical server. So the question is which techno

Thanks Unfortunately yes! this is a production, That's the only thing i have! and I'm going to use ESX (I'm not worried about throughput overhead although stress tests shows no problem with esx some thing like throughput of cassandra on single physical server < 3 * nodes on the same server) If
