Application Processor Overview

Application Field Replaceable Units• The Application Processor (AP) Chassis, motherboard, CPUs• Power supplies in the AP• Disk drives in the AP• FC HBAs in the AP• Fans in the AP• DIMMs in the AP• RMM3 PCB (BMC)

The application processor (AP) is the INTEL SR2600 (URBANA) server that runs the VTL software and CentOS Linux Operating System. The AP provides the interfacebetween the SAN clients and the SGI COPAN storage subsystem. The HBA performs low-level I/O functions with minimal involvement from the controller and controller processors.
