Linux Platforms
Step 1 Download the Performance Test tool
We recommend using the fio utility to test the NVMe RAID array’s performance in a Linux environment.
- Download fio (The following example was created using an Ubuntu 20.04 system):
#apt-get install fio
Step 2 Check the PCIe Lane assignment
WebGUI:
- Start the WebGUI management software and click the Physical Enclosure 1 tab
- SSD7100 Series RAID Controllers require a dedicated PCIe 3.0 x16 slot in order to perform optimally;
- SSD7200 Series RAID Controllers require a dedicated PCIe 3.0 x8 slot in order to perform optimally:
- SSD7500 Series RAID Controllers require a dedicated PCIe 4.0 x16 slot in order to perform optimally:
- If you are configuring a Cross-Sync RAID array, repeat this procedure for Enclosure 2 to check the PCIe Lane assignment.
CLI:
1. Open a command terminal and enter the following command to start the CLI:
#hptraidconf
2. Enter the following command to check the PCIe Lane assignment:
HPT CLI>query enclosures
- SSD7100 Series RAID Controllers require a dedicated PCIe 3.0 x16 slot in order to perform optimally;
- SSD7200 Series RAID Controllers require a dedicated PCIe 3.0 x8 slot in order to perform optimally;
- SSD7500 Series RAID Controllers require a dedicated PCIe 4.0 x16 slot in order to perform optimally;
3. If you are configuring a Cross-Sync RAID array, repeat this procedure for Enclosure 2 to check the PCIe Lane assignment.
Step 3 Configure the RAID Array (e.g. RAID 0)
1. Create a RAID array using the WebGUI or CLI;
WebGUI:
- To configure the NVMe RAID array, access the WebGUI management software, and click the Logical tab.
- Click on Create Array and configure the NVMe SSD’s as a RAID 0.
CLI:
- Open a command terminal and enter the following command to start the CLI:
#hptraidconf
- Enter the following command to check the PCIe Lane assignment:
HPT CLI> create RAID0 disks=* capacity=* init=quickinit bs=512K
2. Format the RAID array; use the following command:
#mkfs.ext4 /dev/hptblock0n* -E lazy_itable_init=0,lazy_journal_init=0
3. Mount the disk:
#mount /dev/hptblock0n* /mnt
Step 4 Start the Performance Test (e.g. RAID0)
- Use a command terminal to select a performance test script that corresponds with the number of CPUs used by the motherboard.
Single CPU performance test
2M continuous reading performance test script：
# fio --filename=/mnt/test1.bin --direct=1 --rw=read --ioengine=libaio --bs=2m --iodepth=64 --size=10G --numjobs=1 --runtime=60 --time_base=1 --group_reporting --name=test-seq-read
2M continuously write performance test scripts：
# fio --filename=/mnt/test1.bin --direct=1 --rw=write --ioengine=libaio --bs=2m --iodepth=64 --size=10G --numjobs=1 --runtime=60 --time_base=1 --group_reporting --name=test-seq-write
4K random read performance test script：
# fio --filename=/mnt/test1.bin --direct=1 --rw=randread --ioengine=libaio --bs=4k --iodepth=64 --size=10G --numjobs=8 --runtime=60 --time_base=1 --group_reporting --name=test-rand-read
4K random write performance test script：
# fio --filename=/mnt/test1.bin --direct=1 --rw=randwrite --ioengine=libaio --bs=4k --iodepth=64 --size=10G --numjobs=8 --runtime=60 --time_base=1 --group_reporting --name=test-rand-write
Multi-CPU performance test
- First, confirm which CPU corresponds with the slot the card is installed into, and then specify this CPU for the performance test.
- Use the following command to view the node corresponding to each CPU, and confirm the cpus value that corresponds with each CPU:
#numactl –H
The node corresponding to CPU1 is 0, and the node corresponding to CPU2 is 1；
The cpus corresponding to CPU1 is：0-11，24-35
The cpus corresponding to CPU2 is：12-23，36-47
- Confirm that the HighPoint NVMe RAID Controller is plugged into the PCIe Slot of the motherboard. If the PCIe Slot used corresponds to CPU1, you need to specify the a cpu value of CPU1 during the performance test. Several workers are used in the script (to correspond with the number of cpus).

# taskset -c 0 fio --filename=/mnt/test1.bin --direct=1 --rw=read --ioengine=libaio --bs=2m --iodepth=64 --size=10G --numjobs=1 --runtime=60 --time_base=1 --group_reporting --name=test-seq-read
