Other Workload Repositories

Other Workload Repositories

UMassTraceRepository

The  Laboratory for Advanced System Software at the University of Massachusetts Amherst has a repository of several types of system traces including two sets of storage traces collected by the SPC.

Unfortunately, all we know about these traces are that two are from  OLTP applications at financial institutions and three are from “a popular search engine”. Since the page that hosts the trace’s download links reports that it was last updated in 2007 we assume the traces are also from no later than 2007.

SNIA IOTTA Repository

Storage Networking Industry Association’s Input/Output Traces, Tools, and Analysis Technical Work Group (IOTTA TWG) has a repository that includes NFS as well as block I/O traces. While these include several multi-hour traces generated by Microsoft in 2008.

Like the UMASS repository there doesn’t seem to be much recent activity at SNIA.

Virtual Instruments WorkLoad Central

Virtual Instruments makes the LoadDynamix workload sensors and load generation appliances. With these tools, organizations can capture and replay their workloads with high fidelity for benchmarking even closer to their real workloads than we’re planning to provide.

They’ve created a community repository at www.workloadcentral.com. These traces are based on performance statistics from storage arrays and Virtual Instruments’ own probes. They have aggregate I/O size and latency data for each time slice of a minute or more but are frequently lacking the spatial data a full trace would provide.

Calypso Systems Test My Workload

Calypso helped develop the SNIA Solid State Storage Performance Test Specification and their testing software is used for most SNIA SSS PTS testing.  They’ve created an IOProfiler that collects storage I/O data and a website TestMyWorkload.com that provides analysis of the data their IOProfiler collects.

Rather than providing a community repository Test My Workload provides visualizations of the workloads a user uploads to that user alone on a freemium model. Basic data is provided free but advanced data like reducibility and LBA range activity are only available as part of paid plans.
