StorONE has introduced what it claims is the first storage platform to enable connectivity between standard mechanical hard disk drives (HDD) and flash drives over NVMe-over Fabric (NVMe-oF) infrastructures, which it says can reduce the cost of an NVMe solution by tenfold or more.
Storage arrays have traditionally been separated by drive make. You have all-flash arrays and all-hard-disk arrays but not a mix of the two. Typical operation is to put “hot” data, or data that is frequently accessed, on the much faster SSDs, and put less frequently accessed data on the slower HDDs. That approach requires two or more separate arrays, plus the connection between them.
