SA Forum's Application Interface Specification (AIS) and Hardware Platform Interface (HPI) specifications address service availability for both software and hardware. OpenSAF 4.0 introduced a new AIS service - the Platform Management Service (PLM), which makes it possible to build “hardware aware” cluster solutions via the use of hardware management stacks such as OpenHPI. This session will show how PLM's ability to “talk to the hardware” is an important feature when building a cluster solution focused on pre-empting and preventing the effects of complete hardware outages. It also includes a demo made up of highly available video streaming components, which broadcasts a movie to clients on the network. The demo will show how a cluster can be made aware of imminent hardware failures and thereby make decisions based on hardware health.

• OpenSAF & OpenHPI
• Demo Setup & Architecture
• Demo

3. Hardware Health & Management
• Get notification of added and
removed hardware
– What hardware is available to use?
• Verify hardware capability
– Type of blade, memory, CPU,
vendor
• Discover faulty hardware prior to
failure
– Elevated temperatures, failing fans
• Manage Hardware
– Turn off hardware that are not used
to save power
– Remote console capabilities

4. OpenHPI
• Implements SA Forum’s Hardware
Platform Interface (HPI)
saHpiEventGet()
• Provides an abstract interface to
programmatically manage computer
hardware
• Communicates with different types of
hardware through a modular plug-in
architecture

5. HP & OpenHPI
At HP we see a lot of customer interest and we are therefore
actively involved in the OpenHPI project and have contributed
2 different plug-ins

9. VLC Server Demo
• In this demo we will show an application
running inside an OpenSAF cluster on a c-
Class chassis (VMs here unfortunately).
• The application is a video server streaming
content to a client over the network
• We will demonstrate 3 different scenarios
− Killing the application manually causes a fail-
over
− HPI event of a high temperature events from a
CPU triggers a fail-over
− A failing fan causes an HPI event. Our policy
manger doesn't trigger a fail-over as there are
several operational fans
