1. SGI Confidential 2- 1 COPAN Components

2. SGI Confidential 2- 2 COPAN 400 Major Components The COPAN 400 platform typically contains the following subcomponents: Cabinet - The structure that houses all of the SGI system subassemblies. Cabling - The cables that connect the various subcomponents, including ethernet, power, USB, fibre channel, and serial cables, etc. I/O Panel - The panel in the back of the cabinet that provides external customer connections to the internal cabinet cabling, such as Ethernet, fiber cable and other cabling. PSM Subsystem: KVM PSM Server Network Switch PSSM Power Subassembly: Power Bay Rectifiers Shelf Subassembly - Up to 8 Shelves in a Cabinet, each containing 8 Canisters Canister Subassembly - Each Canister contains 14 Serial ATA (SATA) hard drives. Application Processor Subassembly – runs the Falconstor VTL software Hosts connect to the subsystem via Fibre Channel (FC) either to the Application Processor for a VTL or directly to the shelf storage enclosures for MAID.

4. SGI Confidential 2- 4 Platform Service Manager & Network Switch The Platform Service Manager (PSM) server is a dedicated server that runs the PSM software, which includes the Service GUI. The PSM software is used to configure, operate, and view the status of the subsystem. The internal 24 port network switch connects the PSM Server and the shelves. The PSM server and network switch are located on the top of the cabinet.

5. SGI Confidential 2- 5 Power Supply Status Monitor The power supply status monitor (PSSM) is located on top of the cabinet. The PSSM has an indicator to provide overall system status. The PSSM connects to the PSM. The PSSM indicator indicates: Illuminates amber if there is a service issue that needs attention. Illuminates green when the cabinet is operating without any service issues.

6. SGI Confidential 2- 6 Keyboard, Video, Mouse The KVM is accessible from a tray on the front of the cabinet. It provides the user keyboard, video and mouse access to the Platform Service Manager (PSM) server.

7. SGI Confidential 2- 7 Application Processor The application processor is the server that runs the VTL software. This provides the interface between 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. The VTL Application Processor runs CentOS Linux operating system. One Application Processor can support 8 shelves. Note: CentOS is a requirement of the Falconstor VTL software.

8. SGI Confidential 2- 8 Power Bay The rack accommodates up to two power bays (Power Bay 0 and Power Bay 1). Each power bay will contain 2 or 4 power rectifiers, depending on the number of shelves being powered. For a redundant system, it is installed in a 2+1 configuration. Front View Rear View

9. SGI Confidential 2- 9 I/O Panel The I/O panel is located in the back of the cabinet. It provides external connections from the customer’s network to the internal cabling in the cabinet. The rear access panel can be removed during service actions that require access to the internal components.

10. SGI Confidential 2- 10 Shelf Assembly The shelf is comprised of one or two shelf controllers, eight Drive Canister modules, a DC-Tray, and an ME-Tray. The SGI COPAN 400 Series may be configured for a minimum of one shelf and a maximum of eight shelves. Storage may be added in minimal increments of one shelf at a time. Each shelf is assembled with eight Canister modules. The canisters must be fully populated with drives.

15. SGI Confidential 2- 15 Power On Procedure 1. Turn on the Power Bays main circuit breakers AC0 and AC1 and verify the 48VDC rectifiers LEDs on the front of the cabinet are green. 2. Slide out the KVM, it will already have power applied to it. 3. The PSM will automatically boot after AC0 and AC1 have been turned on. 4. After the PSM has booted, start the Platform Service Manager Service GUI. 5. Power on each shelf, allowing a two second delay between each shelves. Verify shelf front panel LED status. 6. Once the shelves and shelf canisters appears green in the Service GUI, power on the Application Processors (if any). The Revolution VTL software will start automatically on boot with the resources module taking the longest to load. 7. Verify the Boot Procedure. If there is a POST or Hardware discovery error, a pop-up dialog box will appear and the icons will remain highlighted in black. If this occurs answer NO or OK, and go to the Event Log tab to identify the component that did not boot and make any necessary repair before bringing the shelf online. 8. Execute a trace, which will record the system configuration. This file can be used by technical support to diagnose and troubleshoot hardware errors. Note: Failure to follow this procedure may result in shelves not coming online properly.

16. SGI Confidential 2- 16 Power Off Procedure In order to power off the system properly; it is important to follow this procedures 1. Ensure all I/O has been stopped to each shelf, the shelf to be powered off, or the Application Processor. 2. Execute a trace of the system. Ensure the trace completes before continuing. 3. Connect to the Application Processor(s) (if applicable) and run the VTL revolution console GUI (revolutionconsole) and move all (or applicable) tapes to slots. 4. From the revolutionconsole GUI, perform an X-Ray on the system. The X-Ray will capture all appropriate information, including the VTL event log, as well as a snapshot of the VTL appliance’s current configuration and environment. Save the VTL output file to the PSM. 5. On the Application Processor, from a terminal window issue the ‘revolution stop all’ command. Verify all revolution processes are stopped. 6. From a terminal window issue the ‘halt’ command on the Application Sever. 7. Using the KVM, connect to the BMC interface and power off the Application Processor or press and hold the power button until it is powered off. 8. From the PSM’s Service GUI, stop each shelf (or applicable shelf) by clicking on the ‘stop shelf’ button. After you confirmed that the shelves have stopped in the Service GUI, each shelf can be powered off. 9. To shutdown the PSM server, on a terminal window on the PSM, issue the ‘shutdown –p now’ command or click on the ‘stop PSM’ button on the Service GUI. 10. Remove rack power by switching off the Power Bays circuit breakers AC0 and AC1.
