NVMe cache support

Recommended Posts

Syndicating an NVMe device via RDM will cause it to appear as the type supported by the virtual controller to which it is attached.

In the case of my examples, DSM sees the NVMe drives as SAS.  They could as easily by SCSI or SATA, all to which DSM provides direct support as disk devices.

 

So there will be nothing output from the nvme command structure.

Running in to the exact same issue as Selfmade RuLeZ but with an Samsung 970Pro 512GB nvme ssd. It also does not recognize it's in an m.2 slot?

synonvme --is-nvme-ssd /dev/nvme0n1

It is a NVMe SSD

synonvme --m2-card-model-get /dev/nvme0n1

Not M.2 adapter card

synonvme --model-get /dev/nvme0n1

Model name: Samsung SSD 970 PRO 512GB

Ooo, I wonder if Syno coded their utilities specifically to a particular PCIe address for DS918?  Can anyone with a real DS918+ and a NVMe card run a lspci on their NVMe card?

Hoping for an update here. NetData sees my two NVME drives (8200PRO-256GB) but not Synology.

I believe that it is saying that you do not have an add on card that adds m2 slots.  I get the same message as you do.

It’s getting silent here. I‘ve ordered a NVME to PCIe Card. It‘ll arrive in a few days. I‘ll report if it works✌️

I have an NVME Samsung 970 Evo plus 500GB. Reading the previous post there is no way for the synology DSM to recognize the NVME?

@gadreel if you’ll use esxi+dsm

@Olegin Hi. Thanks for replying. I am using the DSM with Unraid KVM. Can you explain me what I need to do? I mean explain me how that works with ESXI and I will check if I can follow a similar approach on Unraid's KVM.
