Before installing Teamwork Cloud, make sure that the system requirements described in this chapter are met.
Cassandra installation
Teamwork Cloud requires Cassandra installation. To learn more about the hardware requirements for Cassandra, see https://cassandra.apache.org/doc/latest/cassandra/operating/hardware.html
Recommended system requirements
System requirements are dictated by the intended deployment, taking into account the overall load which the environment will experience including:
- Number of concurrent users
- Level of activity (commits) per day
- Overall number and size of the projects stored in Teamwork Cloud.
The database (Cassandra) can be located on the same server as Teamwork Cloud or on a separate server. Storage requirements apply only to the node where the database is located. Teamwork Cloud hosting nodes can be virtualized without any issues if the host is not oversubscribed on its resources.
Nodes containing both Teamwork Cloud and Cassandra
- 96 -128 GB ECC RAM
- >=16 processor threads (such as E5-1660)
- >1TB SSD DAS storage
Nodes containing only Cassandra
- 48 - 64 GB ECC RAM
- >=8 processor threads (such as E5-1620)
- >1TB SSD DAS storage
Nodes containing only Teamwork Cloud
- 48 - 64 GB ECC RAM
- >=8 processor threads (such as E5-1620)
- >250GB storage
Multi-Node Clusters
Recommended minimum sizing stated above applies to each node in a multi-node cluster
SAN Storage
SAN Storage should not be used on Cassandra nodes for data or commit log volumes. This will result in severe performance degradation. There is no amount of SAN tuning and OS tuning which could mitigate this.
Hardware 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 recommended) and 8 GB RAM dedicated for TeamworkCloud
At least 3 separate disks, preferably SSD (NVMe), (OS/Application, Data, and Commit logs). Depending on company backup procedures and infrastructure, an additional disk, equal to the data disk in size, may be required for storing the backup snapshots.
- Cassandra 3.11.x.
- OpenJDK 1.8.0_202 or later used with Cassandra (or Oracle Java). Java 1.8 updated later than 251 cannot be used with Cassandra on the Windows platform.
- OpenJDK 11.0.12 used with Teamwork Cloud.
- FlexNet License Server.
- A static IP address for each node.
Open ports 1101, 2552, 7000, 7001, 7199, 9042, 9160, 9142 and 27000-27009 between servers in a cluster, and open ports 3579, 8111, 8443, 8555 and 10002 (default) to clients. Port number 10002 can be changed according to the port assigned to secure connections between the client software and Teamwork Cloud.
Port Description 1101 FlexLM port 27000-27009 FlexLM ports 2552 TWCloud default remote server port 7000 Internode communication port (not used if TLS is enabled) 7001 TLS Internode communication port (used if TLS is enabled) 7199 Cassandra JMX port 9042 CQL native transport port (used with 2021x version and later) 9160 Thrift client API (used until 2021x version, still required for migrations from 19.0 version) 9142 DSE client port when SSL is enabled 3579 Default port when SSL is not enabled 10002 Default port when SSL is enabled 8111 TWCloud REST API port 8443 TWCloud Admin port 8555 Authentication server port
Software requirements
Supported operating systems:
- Linux (RedHat/CentOS 7), 64 bit.
- Windows 2012 R2, Windows 2016, or Windows 2019.
Operating Systems
We recommend using the Linux operating system. For more information, please visit https://www.datastax.com/dev/blog/cassandra-and-windows-past-present-and-future.
