When running and collecting workload traces of RocksDB, we sometimes see large latency spikes. With this blog, we talk about the methods used to identify the root cause of latency spikes in a mixed read and write workload. 

Google and Meta have worked closely to introduce the Flexible Data Placement (FDP) mode into the NVMe spec. In this blog, our testing shows that FDP decreases write amplification by 60% for sequential workloads.

RocksDB DB bench is Meta’s preferred workload testing methodology as it provides a good emulation of workloads at the query level and simulates precise RocksDB storage I/Os. With this blog, we talk about a test that compares the performance for Micron 7450 vs Samsung PM9A3 vs Solidigm D5-P5430 for RocksDB DB bench.

Here we describe our deeper dive into the Cassandra workload featured in our recently published tech brief comparing 6500 ION performance to a competitor QLC drive. Bursty workloads require SSDs that perform well at high average disk IOs -- an area where the Micron 6500 ION excels.

Check out these testing results for high-performance computing (HPC) and artificial intelligence (AI) using the WEKA Data Platform software. We coupled this software with Supermicro servers built on the 4th Gen AMD EPYC™ 9554 and the Micron 6500 ION SSD.

In this blog, Ceph object storage performance with Micron 6500 ION SSDs is compared to hard disk drives (HDDs). Read this article and see how the 6500 ION wins in performance, power and cost over HDDs.
