Hi, The BOSS card mentioned in that thread should work, however it only supports a few SSDs. [URL]  
BI see this forum post here which suggests certain PCI-E adapters for NVME SSD(s) but it seems like they didn't work. Are there any compatible adapters for an NVME SSD for this particular server? Thank you in advance for your support!  
Looking for a bootable NVME adapter for an PowerEdge R240
