Managing Linux Servers with IBM Wave

Management of Linux servers running on z System usually involves two different skill sets. The z/VM system programming staff and Linux system administrators. Depending on the size of the environment this could be two to many different people. Over the years there have been many approaches to this issue with varying degrees of success.

In many organizations these are very defined responsibilities and roles. The z/VM system programming staff is responsible for setting up the z/VM environment and providing the virtual resources and real disk for a Linux server. Depending on how the Linux server is built or cloned, the z/VM system programmer performs these tasks as well as creating the Linux server or they may pass this off to the Linux administrator to build or complete the setup for this new Linux server.

There is also overlap between the z/VM system programmer and the Linux administrator in the day to day management of these Linux servers. For instance, adding additional disk to a running Linux system would normally require the z/VM system programmer to add this new disk to the Linux server from z/VM and then have the Linux administrator activate the new disk, format it and add it to the Linux server where it is needed. These types of activities are done in an ad hoc manner making is difficult for the either group to have an up to date picture of resources used and what resources are currently available for future use.

IBM Wave can simplify the deployment and management of Linux servers running under z/VM. IBM Wave can help by allowing the z/VM system programmer to manage the overall Linux environment under z/VM and allow the Linux administrator to manage their Linux servers as truly virtual resources.

From a z/VM system programmer perspective, IBM Wave can enable managing pools of resources as apposed to managing individual servers. The z/VM system programmer would set up pools of disk and other resources and allow z/VM and IBM Wave to keep track of the usage of these resources. IBM Wave also allows for reporting on resource usage and can help with planning for additional resources as the environment grows. These new resources can be added dynamically to this environment as needed for easy expansion.

The Linux administrator can manage their environment as a pool of resources as well, as apposed to requesting specific resources for each individual Linux server. They can also see with the various IBM Wave reporting tools what is being used and what is currently available. IBM Wave also allows the Linux administrator to keep track of servers on a project basis enabling the removal of these Linux servers when they are no longer needed and freeing up valuable resources for other projects.

With IBM Wave, the day to day administration no longer requires the involvement of the z/VM system programmer and can be done entirely by the Linux administrator. For example creating a new Linux server or adding disk to an existing Linux server can all be done by the Linux administrator with no z/VM system programmer having to be involved.

Contact your Mainline Account Executive to assist with a more in depth discussion of how IBM Wave can help you manage your Linux servers running under z/VM. Mainline can assist you with everything from providing access to a virtual demonstration all the way up to implementing IBM Wave in your environment.
