Overview and system requirements
Use this guide to install IBM® InfoSphere® Information Server with the optional microservices tier, which includes Enterprise Search, Watson Knowledge Catalog, and the Information Governance Catalog and Information Analyzer console.
The deployment of IBM InfoSphere Information Server with the optional microservices tier (known in version 11.7 as the Enterprise Search node) introduces two new components: Docker and Kubernetes. Other microservices are deployed as containers and pods that are managed by Kubernetes. Docker provides the platform for application deployment by using Docker images and containers, while Kubernetes automates deploying, scaling, and operating application containers.
System requirements
Before you begin the installation, verify that your system meets the following storage, operating system, and memory requirements:
Requirement | Minimum OS | Minimum Memory | Minimum Cores | Minimum Additional Disk Space |
---|---|---|---|---|
InfoSphere Information Server node | See: | 8 GB | 4 | |
Enterprise Search node (version 11.7) | Red Hat Enterprise Linux v7.3 | 32 GB | 8 | 300 GB for persistent volume storage |
Single-node microservices tier without Watson Knowledge Catalog (version 11.7.1) | Red Hat Enterprise Linux v7.3 and above | 32 GB | 8 | 300 GB for persistent volume storage |
Single-node microservices tier with Watson Knowledge Catalog (version 11.7.1) | Red Hat Enterprise Linux v7.3 and above | 64 GB | 16 | 300 GB for persistent volume storage |
Multi-node microservices tier without Watson Knowledge Catalog (version 11.7.1) | Red Hat Enterprise Linux v7.3 and above | 32 GB (each node) | 8 (each node) | 300 GB for persistent volume storage The storage volume can be on any disk on the system or an NFS mount. With local storage, each node must meet this storage requirement. With an NFS mount, the same disk or storage can be mounted on any number of nodes. |
Multi-node microservices tier with Watson Knowledge Catalog (version 11.7.1) | Red Hat Enterprise Linux v7.3 and above | 64 GB (master node) 64 GB (each worker node) |
16 (master node) 16 (each worker node) |
300 GB for persistent volume storage The storage volume can be on any disk on the system or an NFS mount. With local storage, each node must meet this storage requirement. With an NFS mount, the same disk or storage can be mounted on any number of nodes. |

Assumptions and additional requirements
- These procedures assume that you are installing the software as a root user.
- Both the Information Server node and Enterprise Search node must be configured with static IP addresses (no Dynamic Host Configuration Protocol (DHCP)).
- For an Information Server node running on Windows, only Open SSH connectivity is supported.
- The download of the IBM InfoSphere Information Server TAR file and the Docker TAR file requires 20 GB of disk space.
- The Information Server Enterprise Search node must have 6 GB of additional space to extract the Docker TAR file. You can place the file in any directory.
