I’m new, so hopefully I am posting in the correct forum. I’ve been through several OS trials & testing over the last several months, through several hardware systems, and am still looking for an easy to implement OS that can provide the necessary software for achieving high speeds that will saturate 100GbE. QNAP and Synology Hardware, Ethernet and Infiniband, FreeNAS, XigmaNAS, NAS4Free, Xpenology, UnRAID, and I am sure there are some I have forgotten. Now that I’ve established I like the UI and functionality of UnRAID, I need to get my NvME Server going. The aforementioned software options didn’t provide me the ability to consistently saturate anything over 10GbE, so I’m looking elsewhere. The original plan was a tiered system with 16 1 or 2TB NvME’s, 16 SSD’s, and 64 HDD’s. Since I couldn’t find an OS that would do the three tier system while maintaining high transfers speeds/low latency, I am at the crossroads where I need to finally take care of the NvME Server. I have so much surplus, that my configuration options are open. At the very least, I want to utilize -16x 2TB Intel NvME’s -connections to UnRAID servers need to be a minimum capability of saturating 10Gbe -need to be able to at least achieve 40GbE speeds, and preferably 100GbE. -be able to consistently do-so with both Windows and Mac Machines. The client machines all have Chelsio 6200’s or 580’s, as do most servers. Some servers have Mellanox Connectx-3 or connectx-4. And I have a few spare t580’s and ConnectX-4’s. I haven’t been able to find NaS software that will handle, my last thought was to use Windows 2019 for the NvME Server, then hope to find a solution for the potential problems with Mac transfers. Any other options I should be considering?
