Did you ever wonder what the inside of that IBM PureApplication System rack really looks like? Do you need to find out the status of a compute node, networking component or storage component? In most enterprise environments, each of these components is managed and monitored through its own console. PureApplication System provides an easy to use, intuitive, integrated infrastructure system map with some very intriguing features.
There are two views available from the System Console. There is a textual tree view available, but the most interesting view is the graphical view of the hardware from the front of the rack. There is not a rear hardware view. Starting from the bottom of the rack in the Chassis 1, you can see:
- Two compute nodes
- Virtualization System Manager
- PureSystems Manager
Since PureApplication System is fully redundant from a hardware perspective, Chassis 2 is a complete mirror of the configuration in Chassis 1. Moving up the rack, you can see that some of the compute power can be found in the two compute nodes loaded into Chassis 3. And finally at the top of the rack, are two fully redundant top of the rack networking switches that provide connectivity to your enterprise environment.
What if you needed to quickly check the status of a compute node? As shown below, you would first select the compute node. There are several data overlays that give you different views of the compute node. Each data overlay provides specific information. Depending on the information you need to find, you can select a data overlay that is appropriate. In this example, the status overlay was selected and the legend indicates different status conditions. It appears that there is a critical (shown in red) condition on the node. Because of the integrated nature of PureApplication System, it is quite convenient to drill down and discover more information about the compute node and its potential problem.
With the compute node selected, in the upper right side of the infrastructure view is a panel with summary information. There is a wealth of information here. Just above the summary panel is a live link to a more detailed view of the compute node. Since the node has a critical condition, it would make sense to look at the compute node in more detail.
In the following picture, the compute node is highlighted on the left. The location (rack number, chassis number, and node) of the compute node is highlighted. From here, you could look at any number of parameters to diagnose the critical condition. The most likely candidate seems to be an event that was triggered (shown at the top of the panel).
Having selected the live link for the event number, you can see there seem to be two possible errors that are causing a critical condition on the compute node. From here, you could take this information and complete any steps necessary to correct the critical condition.
The integrated features of the hardware infrastructure map can be used for informational or diagnostic purposes. In this case, the infrastructure map indicated a condition that needed attention. By following the appropriate links, you could “chase down” the error, correct it and “circle back” to the original compute node shown on the hardware infrastructure map. The infrastructure map is a prime example of PureApplication System’s simplified experience for diagnosing and correcting system problems. The integrated nature of IBM PureApplication System allows you to quickly and effectively troubleshoot system problems across different components.
Innovative companies continue to look for ways to deliver business value by accelerating time to market, improving application performance, and reducing the staff time needed for many routine ongoing management and support activities.
