HP UCMDB Configuration Manager’s new Clustering Analysis and Policy Enforcement can protect you...

Recently we had a conversation with a US health care service organization and learned they were leveraging HP Universal CMDB Configuration Manager to understand how resilient their J2EE clusters are. With Configuration Manager, they are able to identify single points of failure for their J2EE domains, and understand if they are breaching the high availability standards for their company.

 

Perhaps your situation is that you have a business critical application that needs to be highly available, and you need to ensure that the supporting servers do not physically reside at the same location in order to improve the application’s resiliency and disaster preparedness.

 

You have invested in clustering technology to provide highly available systems, perhaps providing clusters for HP Service Guard, IBM HACMP, J2EE, Microsoft, Oracle RAC, Oracle Sun, or Symantec Veritas. What kinds of points of failure for these clusters can Configuration Manager help identify and avoid?

 

  • Geographical single point of failure – In a virtual environment, configuration policies ensure that the clusters' virtual machine hosts (for example, ESX servers) are located in at least two different locations. In a non-virtual environment, configuration policies ensure that all of the clusters' nodes are located in at least two different locations.
  • Power distribution unit single point of failure – In a virtual environment, configuration policies ensure that the clusters' virtual machine hosts (for example, ESX servers) are connected to at least two different power distribution units. In a non-virtual environment, configuration policies ensure that the clusters’ nodes are connected to at least two different power distribution units.
  • Virtual machine host single point of failure – In a virtual environment, configuration policies ensure that the clusters’ virtual machines are hosted on more than one server (for example, in more than one ESX server).
  • Network single point of failure – In a virtual environment, configuration policies ensure that the virtual machines are connected to more than one virtual switch.

 

Configuration Manager can help you protect your ability to deliver services by analyzing the resiliency of your clusters and enforcing the desired resiliency with configuration policies. With the Advanced Configuration Manager license, you can leverage cluster resiliency policies to identify single points of failure in the environment and ensure that your clusters are symmetrical. Out-of-the-box we provide relevant views and policies for the cluster types that you’re probably already running discovery for today, giving you greater insight into possible points of failure and protecting your ability to deliver services. In addition, you can leverage a new type of policy, similarity policies, to ensure the Configuration Items within clusters are similar. But that’s another topic for a future blog, so stay tuned to hear more about Similarity Policies.
