Excerpt

Before installing Teamwork Cloud, ensure that the system requirements described in this chapter are met.

Note
titleCassandra 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
Info
titleMulti-Node Clusters

Recommended minimum sizing stated above applies to each node in a multi-node cluster.

Warning
titleSAN 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.
Note

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 17.0.8)
  • IMPORTANT. To use modeling tools with DSLS licenses, Microsoft Visual C++ Redistributable must be installed (see

...

...

  • 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:

ServicePortDescription
FlexNet server (lmadmin)1101FLEXnet server port

8090Default vendor daemon port (web browser management port)

27000-27009Internal license server manager port



Cassandra7000Internode cluster communication port (not used if TLS is enabled)

7001Encrypted internode cluster communication port (used if TLS is enabled)

7199JMX monitoring port of the Cassandra node

9042Native client port used to connect to Cassandra and perform operations (used with 2021x version and later)

9142Native client port when SSL encryption is enabled (used when Cassandra is on a separate server or Cassandra is deployed as a multinode cluster)

Info
titleIf deploying on Amazon EC2
When deploying on Amazon EC2, we recommend using the m5-2xlarge, r5-2xlarge, or i3-2xlarge instances. Depending on the workload, you may want to go to the -4xlarge instances, but for most users, the -2xlarge will suffice. The m5 instances meet the minimum system requirements and will be acceptable for small deployments. The r5 instances provide more memory for the same CPU density. The i3 instances should be used when workloads have a higher level of user concurrency due to the significantly improved performance of the ephemeral NVMe storage.
