Q&A / Summary
Importance of Benchmarking
Benchmarking Importance:
Benchmarking enables organizations to assess storage performance metrics against industry
standards, facilitating informed decisions.
Performance Evaluation:
Thorough benchmarking evaluates system performance, optimizing configurations for
increased efficiency and reduced resource allocation.
Key Metrics Identification:
Identifying IOPS, throughput, and latency as critical performance metrics ensures compliance
with service level agreements (SLAs).
Introduction to FIO (Flexible I/O Tester)
I/O Testing Versatility:
FIO supports multiple workload types, enhancing its adaptability for various performance
testing scenarios.
Environmental Simulation:
The tool effectively simulates diverse storage environments, providing realistic benchmarks for
varying use cases.
Integration Capabilities:
FIO's ease of integration with existing frameworks streamlines processes, amplifying
benchmarking efficiency and effectiveness.
Setting Up the Benchmarking Environment
Hardware Requirements: Recommended
specifications include multi-core
processors(32core at least), sufficient RAM, and
high-performance storage devices for optimal
benchmarking.
Software Specifications: Use an up-to-date
operating system compatible with FIO; Linux
distributions generally enhance performance
benchmarking outcomes.
SupremeRAID Configuration: Follow detailed
setup guidelines for SupremeRAID, ensuring
proper environment setup prior to executing
benchmarks with FIO.

Creating FIO Workloads for SupremeRAID
• Basic FIO scripts
• http://{training server}:50089/download-page
• graid-bench script
• https://support.graidtech.com/portal/en/kb/articles/performance-evaluation-by-fio-script-tool
Common Issues and Troubleshooting
• Hardware insufficient: Limited RAM or CPU cores restrict
• Numa-issue
• FIO parameter incorrect: Verify the suggest_fio_script
• PCIe link problem
• SSD performance issue
NUMA in Intel
• Intel has put everything in a large die, and the UPI between socket is also fast, so the
NUMA problem in the intel platform is not serious since the latency between every
CPU core and PCIe device is quite consist

NUMA in AMD
•
The Chiplet architecture brings more challenges on the fabric between dies and sockets
•
Every CCX has limited memory and PCIe bandwidth
•
The latency of each CPU core accessing a different domain memory address or PCIe device
varies greatly
