Two MinIO platforms, same root cause: used as a NoSQL store. Field notes on LIST IOPS, XFS directory limits, scanner & heal SLAs, the erasure-coding storage-efficiency inversion on small objects, and why Apache Cassandra (or Ceph) is the right answer on-prem in 2026.
Note: This article was inspired by a LinkedIn post by Can Sinan A. on the hidden operational cost of an Iceberg migration, especially when governance moves from one access-control plane to several layers: catalog, storage and engine configuration Introduction Many Read more
When Tesla published patent WO2024073080 describing a new file format internally called “.smol”, the headline was simple: 4x reduction in IOPS for AI training. Most people read this as a hardware story. It isn’t. It’s a data architecture story. And Read more
Migrating unmanaged OSDs is one of the operations I run for Ceph clients: Ceph storage consulting. If you are running Ceph Squid with a mix of managed and unmanaged OSDs, there is one thing worth stating clearly upfront: There is Read more
Physicien et inventeur français de l’ESPCI Paris, actif des années 1950 aux années 1970. Un article de référence dans Physical Review Letters en 1977, six brevets français sur l’équilibrage sans contact en soufflerie et les sondes intratubulaires, et une citation comme antériorité dans un rapport du DTIC américain.
GPUs are no longer the bottleneck. Data movement is. The bottleneck in AI infrastructure has moved from compute to data movement. The claim was articulated in an online talk I attended recently, and it matches what I have seen for Read more
Introduction Benchmarking remains a critical (and often underestimated) tool when designing or validating large-scale data platforms. While many teams rely on synthetic workloads or production replays, standardized benchmarks still play a key role when comparing architectures, tuning clusters, or validating Read more
Hidden storage costs are one of the targets of a data platform cost optimization review. Bring the IOPS dude ! As a solutions architect working with MinIO storage solutions, I’ve seen firsthand the challenges that come with on-premises deployments using Read more
Beware the AGPL! you may end with a product orphan from its S3 storage… MinIO has long been a popular open-source S3-compatible storage solution, but their strategy has shifted dramatically, especially since the release of their new AIstor product, now Read more
RBD mirroring in production is one of the patterns I audit and design: Ceph storage consulting. Alpha Feature in Production… Good Idea? The most promising approach, journal-based mirroring, offers near real-time replication and faster failover. However, it’s currently an alpha Read more
