Built-in Test

The Built-in Test page allows you to run performance benchmarks on your storage infrastructure. It provides tools to validate the performance of block storage (using FIO) and object storage (using Warp).

Introduction

The page is divided into two main sections:

• IO Test: Benchmarks disk I/O performance using the Flexible I/O tester (FIO). This is useful for testing Ceph block devices or NFS shares.
• Object Storage Test: Benchmarks S3-compatible object storage performance using MinIO Warp. This supports testing internal (Ceph, MinIO) and external S3 endpoints.

IO Test (FIO)

FIO (Flexible I/O tester) is a standard tool for benchmarking disk I/O. You can use it to simulate specific workload patterns and measure the performance of your storage backend.

Run an IO Test

To start a new IO benchmark:

1. Navigate to the IO Test tab.
2. Click the Create button.
3. Configure the test parameters:
   • Target: Select the storage target (e.g., Ceph Block Pool or NFS).
   • Access Mode: Choose the I/O pattern (Read, Write, Random Read, Random Write, etc.).
   • Block Size: Set the size of I/O units (e.g., 4k, 64k).
   • IO Depth: Define the queue depth for asynchronous I/O.
   • Run Time: Set the duration of the test.
4. Click Confirm to start the test.

Understanding Results

Once the test completes, the results table displays key metrics:

• IOPS: Input/Output Operations Per Second. Higher is better for transactional workloads.
• Bandwidth: Data transfer rate (MB/s). Higher is better for streaming workloads.
• Latency: The time taken to complete an I/O request (Min, Max, Mean). Lower is better.

Object Storage Test (Warp)

Warp is a high-performance S3 benchmarking tool. It is designed to measure the throughput and latency of object storage services.

Run an Object Storage Test

To start a new Object Storage benchmark:

1. Navigate to the Object Storage Test tab.
2. Click the Create button.
3. Configure the test parameters:
   • Target: Select an internal service (Ceph, MinIO) or configure an external S3 endpoint (Host, Access Key, Secret Key).
   • Operation: Choose the operation to test (PUT, GET, DELETE, etc.).
   • Object Size: Set the size of the objects used in the test.
   • Duration: Set the duration of the benchmark.
   • Concurrency: (Optional) Adjust the number of concurrent operations.
4. Click Confirm to start the test.

Understanding Results

The results table provides insights into the object storage performance:

• Throughput: The speed of data transfer (Fastest, Median, Slowest).
• Operations: The rate of object operations (OPS).
• Total Transferred: The total amount of data and number of objects processed during the test.
