Industrial Workload Consolidation

ACRN Industrial Workload Consolidation scenario
|
||||
|
||||
Supporting Workload consolidation for industrial applications is even
|
||||
more challenging. The ACRN hypervisor needs to run different workloads with no
|
||||
interference, increase security functions that safeguard the system, run hard
|
||||
real-time sensitive workloads together with general computing workloads, and
|
||||
conduct data analytics for timely actions and predictive maintenance.
|
||||
|
||||
Virtualization is especially important in industrial environments
|
||||
because of device and application longevity. Virtualization enables
|
||||
factories to modernize their control system hardware by using VMs to run
|
||||
older control systems and operating systems far beyond their intended
|
||||
retirement dates.
|
||||
|
||||
As shown in :numref:`V2-industrial-scenario`, the Service VM can start a number
|
||||
of post-launched User VMs and can provide device sharing capabilities to these.
|
||||
In total, up to 7 post-launched User VMs can be started:
|
||||
|
||||
- 5 regular User VMs,
|
||||
- One `Kata Containers <https://katacontainers.io>`_ User VM (see
|
||||
:ref:`run-kata-containers` for more details), and
|
||||
- One Real-Time VM (RTVM).
|
||||
|
||||
In this example, one post-launched User VM provides Human Machine Interface
|
||||
(HMI) capability, another provides Artificial Intelligence (AI) capability, some
|
||||
compute function is run the Kata Container and the RTVM runs the soft
|
||||
Programmable Logic Controller (PLC) that requires hard real-time
|
||||
characteristics.

Industrial usage scenario:

|

- ACRN boots from the SoC platform, and supports firmware such as the

UEFI BIOS.
|
||||
- The ACRN hypervisor can create VMs that run different OSes:
|
||||
|
||||
- a Service VM such as Ubuntu*,
|
||||
- a Human Machine Interface (HMI) application OS such as Windows*,
|
||||
- an Artificial Intelligence (AI) application on Linux*,
|
||||
- a Kata Container application, and
|
||||
- a real-time control OS such as Zephyr*, VxWorks* or RT-Linux*.
|
||||
|
||||
- The Service VM, provides device sharing functionalities, such as
|
||||
disk and network mediation, to other virtual machines.
|
||||
It can also run an orchestration agent allowing User VM orchestration
|
||||
with tools such as Kubernetes*.
|
||||
- The HMI Application OS can be Windows* or Linux*. Windows is dominant
|
||||
in Industrial HMI environments.
|
||||
- ACRN can support a soft Real-time OS such as preempt-rt Linux for
|
||||
soft-PLC control, or a hard Real-time OS that offers less jitter.
