DataStax Enterprise 3.2

Production deployment planning

The Cassandra 1.2 topic Planning a cluster deployment provides guidance for planning a DataStax Enterprise cluster. The following guidelines are also recommended:

  • Hadoop and Solr nodes require their own nodes/disks and have specific hardware requirements. See the Hadoop and Solr documentation for more information when determining your capacity requirements.
  • DataStax neither supports nor recommends using Network Attached Storage (NAS) because of performances issues, such as network saturation, I/O overload, pending-task swamp, excessive memory usage, and disk contention.
  • If using a firewall, make sure that nodes within a cluster can reach each other. See Configuring firewall port access.
