Dell Technologies has produced several benchmarks based on the STAC-M3 suite in coordination with the STAC Benchmark Council. Each of these benchmarks has four main elements:
The remainder of this section describes some of the test criteria and results and what they mean. For links to each benchmark report, see References.
The STAC-M3 Benchmark specifications marked as “v1” focus on storage system performance. The v1 workloads are deliberately heavy on I/O. The STAC-M3 Benchmark tests can submit requests from independent threads from multiple clients, for example, 10 clients each using 10 threads will create 100 total requesting threads to the storage system.
The prominent v1 storage stress test from the STAC-M3 Antuco benchmark is the VWAB-12DaysNoOverlap benchmark with 100 client threads. This test has a 100 client threads with each thread requesting a 4-hour volume-weighted bid over 12 days for 1% of symbols with no overlap in symbols among client threads. Like the Antuco high concurrency test, the Kanaga benchmark’s VWAB-12D-HO tests also request a 4-hour volume-weighted average bid over 12 days but are different by:
The PowerScale OneFS scale-out file system can easily support thousands of concurrent connections through node distribution and cluster scalability. According to recent public STAC-M3 reports, the PowerScale OneFS file system provided superior results in the high-concurrency and high-thread-count tests.
The STAC-M3 Antuco NBBO test simulates a query of the National Best Bid and Offer (NBBO) across all 10 exchanges for all symbols on the most recent day. This test has a heavy read and write I/O profile and is also heavy on compute intensity. PowerScale NAS storage nodes combined with PowerEdge servers have posted some of the lowest (lower equates to faster query times) NBBO scores across the industry, according to public STAC-M3 Benchmark results.
