11) Check LED status on Xilinx development board. The description of LED is follows.

Table 1 LED Definition

GPIO LED	ON	OFF
0/D4	Normal operation	System is in reset condition
1/R/D5	System is busy	Idle status
2/C/D6	Error detect	Normal operation
3/L/D7	Data verification fail	Normal operation

Figure 2‑10 4-bit LED Status for user output

12) After programming completely, LED[0] and LED[1] are ON for initializing RAID0 system. LED[1] is OFF when RAID0 completes initialization process. Now system is ready to receive command from user. After that, main menu is displayed as shown in Figure 2‑12.

Figure 2‑11 LED status after program configuration file and RAID0 initialization complete

Figure 2‑12 Main menu after program configuration file and RAID0 initialization complete

13) If some SATA devices cannot be detected, error message (CH[X] Not Detect) will be displayed as shown in Figure 2‑13. Please check SATA device in error channel.

Figure 2‑13 Error message when some devices cannot be detected

3 Test Menu

3.1 Identify Device

Select ‘0’ to send Identify device command to RAID0. When operation is completed, four device details are displayed on the console, i.e.

1) SSD model number

2) Security feature set is supported or not supported. If some devices are not supported, user must not use menu 3 for the test.

3) Normal Erase Mode Time: The estimation time to complete security erase command, returned from SATA device. Minimum valid value is 2 minutes. This information will be displayed when SATA device supports Security feature set.

4) RAID capacity: Capacity which is output value from RAID0 block. The value is calculated by (4 x SATA CH#0 capacity).

3.2 Write SSD

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 can be decimal unit or add “0x” as a prefix “0x” for hexadecimal unit.

2) Sector Count: Input total transfer size in sector unit. The input can be decimal unit or add “0x” as a prefix for 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 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 SSD menu

Figure 3‑3 Example Test data in sector#0/#1 of 4 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), 32-bit increment pattern.

Stripe size in 4-ch RAID0 demo is 1 sector (512-byte). So, LBA address in the header of 1^st sector in Disk#0, Disk#1, Disk#2, and Disk#2 are equal to 0, 1, 2 and 3 sequentially. The address in the header of the next sector for Disk#0 is 4.

Figure 3‑4 – Figure 3‑6 show error message when user input is invalid. “Invalid input” message is displayed on the console. Then, it returns to main menu to receive new command.

Figure 3‑5 Invalid Sector count input

Figure 3‑6 Invalid Test pattern input

3.3 Read SSD

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 can be decimal unit or add “0x” as a prefix for hexadecimal unit.

2) Sector Count: Input total transfer size in sector unit. The input can be decimal unit or add “0x” as a prefix for 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 test if all inputs are valid, test system will read data from RAID0. 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 SSD menu

Figure 3‑8 and Figure 3‑9 show the error message when data verification is failed. “Verify fail” message 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.

“RESET” button must be pressed to restart the system when user cancels the operation.

Figure 3‑8 Data verification is failed but wait until read complete

Figure 3‑9 Data verification is failed and input any keys to cancel operation

3.4 Security erase

Select ‘3’ to send Security Erase command to RAID0. Please confirm that all SATA devices support Security Erase feature by using Identify device menu. The estimation of operation time to run security erase is also displayed in Identify device menu.

After selecting the menu, warning message is displayed on the console. User input ‘y’ or ‘Y’ to continue security erase operation or input other keys to cancel operation.

Number 0-9 is displayed on the console every second to show that system still run alive. Finally, total time usage is displayed as shown in Figure 3‑10.

Figure 3‑11 shows the example when user inputs other keys to cancel the command.
