I'm thinking about getting a few cheap Dell rack nodes and filling them with M.2 NVMe drives via PCIe slots ideally for some form of clustered storage. Due to a lack of slots for an NVMe boot drive (CentOS 7), I'm considering using a 12G SAS SSD instead - probably a HGST Ultrastar SSD1600MR.
If it runs about 1GB/s throughput, is that going to be a significant bottleneck for the NVMe volumes? Especially if I start RAIDing them together? Or will the system memory cache make that a non-issue? I'll have at least 64GB RAM. The use case is mainly film post production/vfx, and possibly some machine learning. Thanks!
