First install Java on each node that needs to be tested (including the master node)2. then ensure that the hostname of each node is different, and it is best to shut down each firewall3. mount the networked storage you want to test on each node4. then operate each node sequentially, enter the Vdbench directory with cmd an

Why caching is an important element in enhancing SmartCloud input/output performance To understand the transient storage performance in the SmartCloud environment, we set up a benchmark test using Vdbench. Vdbench is an I/O workload builder that validates data integrity and measures the performance of storage for direct attach and network connectivity. It is a free tool that is easy to use and is often use
