Hi, I'm trying to use the NVMf storage tier provided by Crail. However, I'm a little confused about how it works and the documentation is misleading and unclear.
The documentation on the website (https://incubator-crail.readthedocs.io/en/latest/config.html) says that the NVMf tier can only be used for metadata and not data, but the blog post (https://crail.incubator.apache.org/blog/2017/08/crail-nvme-fabrics-v1.html) shows it being used to store data. So, which one is true? Secondly, with NVMf, do I need to run the datanode processes or does the NVMf target serve as the datanode process? Which NVMf target should I use? Can I use the SPDK NVMf target or does Crail provide its own version? If it does, then where do I find it and how can I get it running? Thanks, Shashank
