elbencho is a command-line storage benchmark designed as one unified tool for testing file systems, object stores and block devices.
It can run on one machine or across multiple systems, making it suitable for local SSD measurements as well as shared and distributed storage. Its workload model focuses on latency, throughput and IOPS, with controls for repeatable tests across NVMe devices, conventional disks and larger storage infrastructure.
This is free and open source software.
Key Features
- Runs local or distributed benchmarks through a service mode for testing shared storage from multiple clients.
- Supports multi-threaded workloads and asynchronous I/O through libaio.
- Can exercise file storage, block devices and S3-compatible object storage from the same benchmark application.
- Measures GPU storage-access performance through Nvidia CUDA and GPUDirect Storage.
- Provides live statistics while a workload is running so changes in behaviour under load are visible.
- Reports aggregate results at both the first and last finishing thread, separating the tail phase from the main workload.
- Exports results to CSV and JSON for analysis with the accompanying chart and JSON-summary tools.
- Offers data-integrity verification to check that test data can be read back correctly.
- Supports configurable block-size mixes and offsets to target particular I/O-size distributions and regions.
- Includes reusable configuration files plus examples for Slurm and Kubernetes environments.
- Can be built with optional S3 and NVMe-oF support, including SPDK-based NVMe-oF initiator testing.
