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…

Of course, this is a functionality test and not a production POC. In addition to understanding and observing the aggregate performance that only 3 active OSS nodes can deliver, I wanted to test 2 failover systems between OSS1 and OSS2 nodes (OSS3 is unpaired and works without failover). 1 - The…
