Before installing Teamwork Cloud, ensure 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 for data or commit log volumes on Cassandra nodes. This will result in severe performance degradation. There is no amount of SAN tuning and OS tuning which could mitigate this.
Minimal hardware requirements
For adequate Teamwork Cloud operation, your hardware should meet the following 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 Teamwork Cloud
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 size, may be required to store the backup snapshots.
Software requirements
Teamwork Cloud supports the following operating systems:
Linux 64-bit RedHat 8, RedHat 9, Oracle Linux 8.
- Windows 2016 or Windows 2019.
The Linux operating system is highly recommended for Teamwork Cloud deployment. Cassandra 4 does not have native Windows support. For more information, please visit https://www.datastax.com/dev/blog/cassandra-and-windows-past-present-and-future.
For a fully working environment, you will also need the following:
- Cassandra is compatible with OpenJDK 11.0 (tested with Eclipse Temurin™ by ADOPTIUM 11.0.14)
- Teamwork Cloud is compatible with OpenJDK 17.0 (tested with Eclipse Temurin™ by ADOPTIUM 17.0.11)
- IMPORTANT. To use modeling tools with DSLS licenses, Microsoft Visual C++ Redistributable must be installed (see Latest supported Visual C++ Redistributable downloads). This applies to Windows OS only.
- FlexNet or DSLS license server
- Cassandra 4.0.x, 4.1.x
- A static IP address for each node
Open ports 1101, 2181, 2552, 7000, 7001, 7199, 9042, and 9142 between servers in a cluster
Open ports 3579, 8111, 8443, and 10002 (default) for clients. The port number 10002 can be changed according to the port assigned to secure connections between the client software and Teamwork Cloud.
The following table lists the ports that Teamwork Cloud services use and their descriptions:
| Service | Port | Description |
|---|---|---|
| FlexNet server (lmadmin) | 1101 | FLEXnet server port |
| 8090 | Default vendor daemon port (web browser management port) | |
| 27000-27009 | Internal license server manager port | |
| Cassandra | 7000 | Internode cluster communication port (not used if TLS is enabled) |
| 7001 | Encrypted internode cluster communication port (used if TLS is enabled) | |
| 7199 | JMX monitoring port of the Cassandra node | |
| 9042 | Native client port used to connect to Cassandra and perform operations (used with 2021x version and later) | |
| 9142 | Native client port when SSL encryption is enabled (used when Cassandra is on a separate server or Cassandra is deployed as a multinode cluster) | |
| Teamwork Cloud | 2552 | Teamwork Cloud default remote server port |
| 3579 | Default Teamwork Cloud port when SSL is not enabled | |
| 8111 | Teamwork Cloud REST API port | |
| 10002 | Default port when SSL is enabled | |
| Web Application Platform | 8443 | Web Application Platform port (Teamwork Cloud Admin, Collaborator…) |
| Zookeeper | 2181 | Zookeeper internal port |
