Vdbench: Open Source Disk I/O Workload Generator and Measurement Tool
Vdbench is an open source disk I/O workload generator and measurement tool for storage systems. It can generate workloads to simulate real-world I/O patterns for benchmarking and analyzing storage performance.
What is Vdbench?
Vdbench is an open source disk I/O workload generator and measurement tool used for benchmarking and analyzing storage system performance. It can generate I/O workloads that simulate real-world application behavior to help understand storage system capabilities.
Some key features of Vdbench include:
- Generates standard workloads like sequentials, random reads/writes
- Custom workload profiles based on traces and real app behaviors
- Multi-threaded and multi-process operation
- Reporting of IOPS, latency, and bandwidth
- Supports all storage protocols including SAN, NAS, Object
Vdbench enables benchmarking of physical devices as well as storage virtualization layers like virtual machines, containers. It is widely used by storage hardware and software vendors, researchers, IT organizations for storage testing and validation.
