Linbit Unveils 14.8 Million IO/s WW Record for Hyperconverged Storage

Linbit HA-Solutions GmbH, the force behind the open-source DRBD data replication software and its SDS, built a hyperconverged cluster that outperformed the previous performance record by 7.2% and reduced latency by 10%.

Here are results:

14.8 million remote read IO/s
10.6 million IO/s with 70/30 mixed read/write
5.0 million synchronously replicated random write IO/s
85μs synchronously replicated write latency

The 14.8 million read IO/s test toppled the record formerly held by proprietary software vendors, proving that Open Source SDS provides enterprise class performance.

These results use a container-based system with 3-way synchronous replication for highly available persistent storage. The 12 server test cluster, consisting of standard off-the-shelf Intel Corp.‘s servers, was provided through the Intel Data Center Builders program. The cluster is hyperconverged, meaning that the same servers are used to run the benchmark and to provide the underlying storage.

In a performance test, the company measured 14.8 million IO/s. This is the highest storage performance reached by a hyperconverged system on the market, for this hardware basis. The test demonstrates that even a small LinStor storage system can provide millions of IOP/s at microsecond latencies. For real world applications, the company also tested 70/30 read/write workloads and the results of greater than 10 million IO/s correspond to outstanding application performance.

More technical details are provided in their blog post about the setup.

The company chose this setup because its competitors have published test results from equivalent systems. Previously Microsoft managed to reach 13.7 million IO/s, and Storpool marginally topped that with 13.8 million IO/sS. The firm reached 14.8 million remote read IO/s – a jump of 7.2%. Those performance numbers mark a milestone in the development of open-source SDS platforms. The numbers would scale up even further with a larger setup.
