Customers have long been familiar with OakGate SVF Pro and LeCroy Analyzer tools. Our new WorkloadIntelligence™ Analytics tool allows customers to derive even more benefit from their existing tools.
Because most tools report data as averages and histograms, some problems can be hard to identify and correlate. In addition, problems that span multiple layers can also be hard to identify and correlate.
Analytics provides a means to deal with both of these issues. Teledyne LeCroy has developed a suite of advanced software tools called WorkloadIntelligence
that delivers on the promise of providing analytics and replay capabilities for testing SSDs with real-world workloads
This white paper shows a comparative analysis of storage industry SSDs using Teledyne LeCroy WorkloadIntelligence™ Analytics application.
A datacenter workload, a Linux block trace provided by one of our Teledyne LeCroy hyperscale data center customers, was used for the
comparative analysis. The goal for the comparative analysis was to see how other industry SSDs handle the same burst of latency I/Os highlighted in the trace.
The trace was captured using a customer’s production system and replayed on an OakGate appliance. Because Teledyne LeCroy uses a proprietary driver, which sits in
user space and tunnels through directly to the hardware, we are able to faithfully reproduce the workload to the drive without operation system induced variation in the workflow.
This white paper describes the benefits of using real-world workloads and how real-world workloads can be analyzed for data center improvements.
This white paper addresses the need and issues of transitioning to SSDs in the data center,
as well as the current and future trends of qualifying SSDs in the data center.
