Transcription

1 2-Ch RAID0 (NVMe-IP) Demo Instruction Rev May-18 This document describes the instruction to run 2-ch RAID0 by using NVMe-IP on FPGA development board and AB17-M2FMC board. The demo is designed to write/verify data with two M.2 NVMe SSDs as RAID0 operation. It is recommended to use same SSD model for both SSDs. User controls test operation through Serial console. 1 Environment Requirement To run the demo on FPGA development board, please prepare following environment. 1) FPGA Development board: KCU105 2) PC installing Xilinx programmer software (Vivado) and Serial console software such as HyperTerminal 3) AB17-M2FMC board, provided by Design Gateway 4) Xilinx power adapter for FPGA board 5) Two M.2 NVMe SSDs, inserting to M.2 connector on AB17 6) Two micro USB cables for programming FPGA and Serial console, connecting between FPGA board and PC Figure 1-1 NVMe-IP RAID0 demo setup by AB17 on KCU May-18 Page 1

2 2 Demo setup 1) Power off system. 2) Connect two M.2 NVMe SSDs to Drive#1 and #2 connector on AB17-M2FMC. 3) Connect AB17-M2FMC to HPC connector (J22) on KCU105, as shown in Figure 2-1. Figure 2-1 Connect AB17 to FPGA board 4) Connect two micro USB cables between FPGA board and PC for FPGA programming and Serial console. Figure 2-2 USB cable connection 31-May-18 Page 2

3 5) Turn on power switch of AB17-M2FMC and FPGA development board, as shown in Figure 2-3. Figure 2-3 Turn on power switch 6) On PC, there are two additional COM ports from FPGA connection, as shown in Figure 2-4. Open Serial console program such as TeraTerm, HyperTerminal to connect with Standard COM port for running the demo. On Serial console, set Buad rate=115,200, Data=8 bit, Non-Parity, Stop=1. Figure 2-4 Two COM ports from FPGA connection 31-May-18 Page 3

4 7) Set VADJ of FMC. Open Serial console to connect with Enhanced COM port (Buad rate=115,200 Data=8 bit Non-Parity Stop=1). The console shows System Controller menu, as shown in Figure 2-5. To set VADJ of FMC to 1.8V, the following step is recommended. (1) Input 4 to select Adjust FMC Settings. (2) Input 4 to set FMC VADJ to 1.8V. (3) Input 0 to return to Main Menu. (4) Input 2 to get PMBUS Voltages. (5) Input 7 to get VADJ1V8 Voltage. The output voltage of this menu must be equal to 1.8V to confirm that VADJ has been set completely. For more details of System Controller, please check UG917 KCU105 Board User Guide in section Appendix C: System Controller. u105-eval-bd.pdf Note: If Serial console is opened after power-on board for long time, the main menu of System controller may not be displayed on the console. User can input 4 to select Adjust FMC settings menu. Figure 2-5 Setting VADJ of FMC 31-May-18 Page 4

5 8) Use Vivado tool to download configuration file, as shown in Figure 2-6. Figure 2-6 Programmed by Vivado 9) Check LED status on FPGA board. The description of LED is as follows. GPIO LED ON OFF 0 Normal operation SSD is not good status 1 System is busy Idle status 2 IP Error detect Normal operation 3 Data verification fail Normal operation Table 2-1 LED Definition 31-May-18 Page 5

6 10) After programming completely, LED[0] and LED[1] are ON during RAID0 initialization process. Then, LED[1] changes to OFF after RAID0 completes initialization process and system is ready to receive command from user. After that, main menu is displayed as shown in Figure 2-8. Figure 2-7 LED status after program configuration file and RAID0 initialization complete Figure 2-8 Main menu after program configuration file and RAID0 initialization complete 31-May-18 Page 6

7 3 Test Menu 3.1 Identify Command Select 0 to send Identify command to RAID0. When operation is completed, all information is displayed on the console, i.e. 1) SSD model number for two channels. 2) RAID0 capacity which is output value from RAID0 block. The value is equal to two times of CH#0 SSD capacity. Figure 3-1 Result from Identify Command menu 31-May-18 Page 7

8 3.2 Write Command Select 1 to send Write command to RAID0. Three inputs are required for this menu. 1) Start LBA: Input start address of RAID0 in sector unit. The input is decimal unit when input only digit number. User can add 0x to be prefix when input is hexadecimal unit. 2) Sector Count: Input total transfer size in sector unit. The input is decimal unit when input only digit number. User can add 0x to be prefix when input is hexadecimal unit. 3) Test pattern: Select test pattern of test data for writing to RAID0. Five types can be selected, i.e. 32-bit increment, 32-bit decrement, all 0, all 1, and 32-bit LFSR counter. As shown in Figure 3-2, if all inputs are valid, the operation will be started. During writing data, current transfer size is displayed to the console every second to show that system still be alive. Finally, test performance, total size, and total time usage are displayed on the console as test result. Figure 3-2 Input and result of Write Command menu 31-May-18 Page 8

9 Figure 3-3 Example Test data in sector#0 and #1 of 2 devices by LFSR pattern Test data of each sector has different 64-bit header which consists of 48-bit LBA address and 16-bit all 0 value. 48-bit LBA address is unique value for each sector. After that, the test pattern is filled following user selection such as 32-bit LFSR pattern (as shown in Figure 3-3) Stripe size in 2-ch RAID0 demo is 1 sector (512-byte). So, the 1 st sector of RAID0 is mapped to the 1 st sector in Disk#0 and the 2 nd sector of RAID0 is mapped to the 1 st sector in Disk#1. The header of each sector shows LBA address of RAID0. As shown in Figure 3-3, the header of the 1 st sector in Disk#0 and Disk#1 are equal to 0 and 1, and the header of the next sector for Disk#0 and Disk#3 are equal to 2 and May-18 Page 9

10 Figure 3-4 Figure 3-6 shows error message when user input is invalid. Invalid input message is displayed on the console, and then returns to main menu to receive new command. Figure 3-4 Invalid Start LBA input Figure 3-5 Invalid Sector count input Figure 3-6 Invalid Test pattern input 31-May-18 Page 10

11 3.3 Read Command Select 2 to send Read command to RAID0. Three inputs are required for this menu. 1) Start LBA: Input start address of RAID0 in sector unit. The input is decimal unit when input only digit number. User can add 0x to be prefix when input is hexadecimal unit. 2) Sector Count: Input total transfer size in sector unit. The input is decimal unit when input only digit number. User can add 0x to be prefix when input is hexadecimal unit. 3) Test pattern: Select test pattern to verify data from RAID0. Test pattern must be matched with the test pattern which is used during write test. Five types can be selected, i.e. 32-bit increment, 32-bit decrement, all 0, all 1, and 32-bit LFSR counter. Similar to Write command menu, if all inputs are valid, test system will read data from RAID0. During reading data, current transfer size is displayed on the console every second. Finally, test performance, total size, and total time usage are displayed after end of transfer. Invalid input will be displayed if some inputs are out-of-range. Figure 3-7 Input and result of Read Command menu Figure 3-8 and Figure 3-9 show error message when data verification is failed. Verify fail is displayed with error address, expected data, and read data. User can press any key to cancel read operation or wait until all read process complete. If read process is completed, output performance from read process will be displayed. In case of cancel operation, the previous command does not complete in good sequence. It is recommended to power-off/on AB17 and press RESET button to restart system. 31-May-18 Page 11
