We have clusters at work, but they have quite different hardware. For HA clusters we indeed use bcache on quite durable Intel SSD (400 GB size, 8PBW resource). For HPC cluster we planned SSD cache for storage, but due to funding cut-off we have only small SSDs on each node. Best regards, Andrew Savchenko
