Recommended System Specifications (Clustered Environment) – Maximo 7.6
Deciding on the correct hardware for a clustered Maximo environment can be a challenging task. Not all servers in a clustered environment serve the same function, nor are they subject to the same hardware load. This often creates some confusion, as hardware choice is server-type specific. Additionally, finding these specifications can sometimes be a bit of a challenge.
In this post, I have outlined all of the hardware specifications described by IBM required to support a clustered Maximo environment.
The physical memory recommendations in this post are based on the following heap size recommendation by IBM for Maximo 7.6:
| APPLICATION SERVER | |
| Platform/hypervisor | Virtualized or Physical Machine |
| Processor | Intel Xeon Processor (Or Similar) |
| Memory | See below for memory calculation |
| CPU Count | 4 |
| Disk | C:\ (Windows) 60GB E:\ (Installations) 100 GB F:\ (Network Drive) – Attached documents will be stored on the file server |
| O/S | Windows Server 2012 Windows Server 2012 R2 Windows Server 2016 AIX Red Hat |
Initial: 6144m / Maximum: 6144m (Recommended)
Initial: 4096m / Maximum: 4096m (Minimum)
Note: Recommend Windows Server 2016.
Ram Requirements breakdown:
| WebSphere Deployment Manager | JVM (Cron, MIF, UI) | JVM (RMI) | HTTP Server | Node Agent | O/S and Misc. | |
| Memory | 1GB | 6GB | 512MB | 256MB | 512MB | 4GB |
For Example:
An application server is running an O/S, 2 UI JVMs and 1 Node Agent. The calculation based on the above chart breaks down as follows:
| Maximo JVM x 2 | 6 GB x 2 |
| O/S and Misc | 4 GB |
| Node Agent | 512 MB |
| = 16.5 GB |
