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
- 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 commitlog volumes. This will result in severe performance degradation. There is absolutely no amount of SAN tuning and OS tuning which will mitigate this.
Minimum 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 always preferred on any critical database server) and 8 GB RAM for TWCloud Admin.
- 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.
Software requirements
Teamwork Cloud supports the following operating systems:
Linux (RedHat/CentOS 7), 64 bit
Windows 2012 R2, Windows 2016.
Operating 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.
For a full working environment, you will also need:
- Oracle Java/OpenJDK 1.8.0_202 or later (for Cassandra 3.11-x). Java 1.8 updated later than 251 cannot be used with Cassandra on the Windows platform.
- OpenJDK 11.0.12 (for TeamworkCloud).
- FlexNet License Server.
- Cassandra 3.11-x.
- 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.
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 | License server manager port | |
| Cassandra | 7199 | Cassandra JMX port |
| 9042 | CQL native transport port (used with 2021x version and later) | |
| 9160 | Thrift client API port (used until 2021x version, still required for migrations from 19.0 version) | |
| 9142 | DSE client port when SSL is enabled | |
| Teamwork Cloud | 2552 | Teamwork Cloud default remote server port |
| 3579 | Default Teamwork Cloud port when SSL is not enabled | |
| 7000 | Internode communication port (not used if TLS is enabled) | |
| 7001 | TLS Internode communication port (used if TLS is enabled) | |
| 8111 | Teamwork Cloud REST API port | |
| 10002 | Default port when SSL is enabled | |
| Web Application Platform | 8443 | Web Application Platform port (TWCloud Admin, Collaborator…) |
| Authserver | 8555 | Authentication server port |
