<p class="MsoNormal">Yes – definitely let the list know how/if it all works – I’ve been eyeballing the EPYC based TN70A-B8026 which is 2U and 24 hotswap NVMe that are direct attached. I think the supermicro ones are all going to be via PLX PCI expanders since
Intel doesn’t have enough PCI express lanes even in 2P for 24x more less 48x not that it probably matters that much. FWIW, Phoronix reviewed this Tyan system, and couldn’t get OmniOS (r151122CE I think) to see the nvme drives – but I don’t know how hard he
tried nor do I know what kind of drives they sent him for review.<o:p></o:p></p>

<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif;color:black">we are planning on purchasing a Supermicro NVMe server with 48 .U2 slots. I intended to initially load it with 24 x 2TB DC P4500, leaving 24 slots empty.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif;color:black">Now… I've been also offered an Intel chassis with only 24 slots and thus the offer also included the 4TB P4500s. Just without thinking very long, I instinctively
wayed towards the 2TB drives, mainly for the reason, that should a drive really fail, I'd have of course a longer resilver at hand, usind 4TB NVMe drives.<o:p></o:p></span></p>
