How to Choose the Right Storage Platform for Each Workload Every few years the storage industry reinvents the same lie. One platform that does everything. Vendors love it because it simplifies sales. Architects love it because it simplifies diagrams. Technicians hate it because physics still exists. Latency, throughput, metadata handling, failure domains and recovery behavior are not marketing features. They decide whether a platform is fast, stable or painful to operate. When storage is chosen wrong, no amount of tuning…

It offers object, block, and file storage in a single distributed system, with high availability, strong durability, and the ability to scale on standard hardware.That alone makes Ceph exceptional. But here is the uncomfortable truth: Ceph can scale massively and still be the wrong storage for a specific workload. Understanding why is the difference between a great architecture…

The guarantee refers to minimum allocated capability, not to the performance your application will actually experience. 1. Guaranteed IOPS = minimum capability, not magic performance “Guaranteed IOPS” is about capacity, not about how fast every single I/O will feel to your application. Providers typically base their guarantees on ideal, synthetic tests (e.g. 4K random reads/writes, high queue depth). In reality:…
