Go to start of metadata

Both Teamwork Cloud (TWCloud) and Cassandra installation is required. This section contains system requirements for your machine to install TWCloud. You can see the hardware requirements for Cassandra at https://wiki.apache.org/cassandra/CassandraHardware


Minimum server system requirements: 

  • 8 Processor Cores - i.e. Quad Core Hyper-threaded CPU (such as Intel E3-1230 or faster).
  • 32 GB RAM (Motherboard with an ECC RAM is always preferred on any critical database server).
  • Linux (RedHat/CentOS 7), 64 bit and Windows Server 2012 R2.

    Operation Systems

    Although Windows is supported, we recommend using Linux. For more information, please visit https://www.datastax.com/dev/blog/cassandra-and-windows-past-present-and-future.

    Centos 6.6 - 6.9

    Scripts need to be modified slightly for Centos 6.6 - 6.9 due to different system daemon and firewall configuration.

  • Cassandra 2.2.8
  • Oracle Java (Java Hotspot) 1.8.0_152
  • A FlexNet License Server
  • Open port 2552 between servers in a cluster, and open ports 3579, 8111, and 8555 (default) to clients 
  • Static IP address for the node 

Compatibility Remark

TWCloud 18.5 is not compatible with Cassandra 3.x.x.

Please read the article for additional server recommendations for capacity and performance from the following link:

https://docs.datastax.com/en/cassandra/2.2/cassandra/planning/planPlanningHardware.html

If you use SATA drives and not SSD's, we recommend using a caching controller with BBU, configured for write back. In this configuration (single node Cassandra), we recommend using RAID - the aforementioned link is referring to multi-node Cassandra deployments where native Cassandra replication is in place, which is not the case in this single node instance.
