Hello! I am looking for a little clarification on the IO-Cache performance translator. More specifically, how it behaves with large files. Here is what I intended to architect: large SATA arrays (24T) that also have somewhat large (60-360G) SSD storage drives for caching. I wanted to use the SSD drives as both an XFS journal and also as a GlusterFS cache. The problem is that the files I'm serving are qcow2 (virtual disk) files anywhere from 2GB to 400G files. I'm wondering how to get GlusterFS to utilize the SSD to speed performance.
