Abstract
This paper combines the efforts and talents of the IBM
System z™ New Technology Center, the eServer™ High Availability Center of
Competence, and Linux® on System z Integration Test to produce a set of
reference architectures that provide High Availability for applications
running on Linux for System z.
This paper focuses on those architectures that cover the following
scenarios:
Where the application runs on Linux virtual servers under z/VM®. The
database may be on Linux for System z or on z/OS®.
Of highest interest to our customers.
Unique to System z. Not covered are scenarios and architectures that have
already been documented on other distributed platforms. WebSphere® HA has
been extensively covered in many documents. Although our architectures
will use HA features of WebSphere, we will not concentrate on documenting
WebSphere. (Please see the references section for more WebSphere HA
documentation). Rather, we will concentrate on the HA aspects of the
database servers that WebSphere applications would use and how System z HA
features can benefit database servers.
Have not been documented before on System z.
This paper does not cover:
All the details necessary to implement the reference architectures. For
those details, please refer to “System z Platform Test Report for z/OS and
Linux Virtual Servers” written by the IBM Poughkeepsie Test and
Integration Center for Linux.
HA networking considerations. We cover the major components and flow
between them. We have not covered how to create a highly available
network.
How to HA-enable your storage subsystem.
