Production deployment planning

Production deployment planning requires knowledge of the initial volume of data to store and an estimate of the typical application workload.

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.
