Can ESXi/DSM handle VROC?

Recommended Posts

Hi all,

I am planning on building a NAS/server solution and have come across the option of using VROC. I am planning to virtualise DSM over ESXi. I understand that ESXi can "RDM" NVMe drives as SCSI. Does this also work for VROC? (Virtual RAID over CPU)

Thanks! J

Hi @bearcat, thanks for your quick response. This is my current list:

Fractal Design NODE 304

Fujitsu D3417-B2 MB C236-AMT

Xeon E3-1245 v6

ASUS HYPER M.2 X16 Card (which supports VROC)

32 GB RAM, 4 HDDs, 2-5 NVMe SSDs depending on whether or not VROC is supported (since I assume that would be the preferred way to realise data redundancy on the NVMes?)

Thanks, J

VROC is another form of hardware RAID, which displaces much of the functionality that DSM provides around storage redundancy management.

 

Also, I think VROC is really only a very high-end Xeon product implementation... and not generally available on the hardware on which XPEnology is likely to be run.

 

Lastly, using NVMe is currently only possible within very specific parameters using ESXi, and I'm not sure how a VROC implementation would play into that.

Maybe this question would have better fit the Noob section - sorry for that.

 

Thanks for your responses @bearcat and @flyride

 

@flyride, are you saying that with the DSM/Xpenology software I can create a RAID volume on the NVMe drives anyway? Regardless of the hardware?

 

Thanks again! :)

There are currently two options to make NVMe work as a RAIDable disk; both require virtualization.

 

You can set up a datastore and create a virtual disk.  Or, with ESXi, create a physical RDM definition for the NVMe drive.
