Vdbench
Vdbench is a disk I/O benchmarking tool originally developed by Sun Microsystems and now maintained by Oracle. It generates configurable storage workloads to measure performance of storage arrays, disks, and related devices. The tool supports a range of I/O patterns and configurations, making it a common choice for capacity planning, vendor performance validation, and database or virtualization storage testing.
Workloads are defined in a description file that specifies devices, targets, and operations. Vdbench can mix
Vdbench runs on Unix-like systems, including Linux and Solaris, and is distributed as part of Oracle's benchmarking
Because results depend on hardware, software stack, and configuration, Vdbench is used to compare configurations and
