Nvme -of disks in clustered storage spaces

[jdeshin]

Hi StarWind Staff!
According to your technical papers:
https://www.starwindsoftware.com/nvme-o ... me-cluster
and
https://www.starwindsoftware.com/resour ... ws-server/

I have following question:
Can I create clustered storage space on your nvme-of disks for redundancy? Did you make any tests?

Best regards,
Yury

Hi Yury,

HA is not available for NVMe-oF targwts. It is on the road map, stay tuned!

Dear Yaroslav,
In your second technical parer you say that it is possble to make nvme-of drive as a clustered shared volume.
Can I use that drive in clustered storage spaces for redundancy? It's standard Windows Server functionality.
For example, I have few nvme-of drives, then I will add those to clustered storage space and then to create mirror volume for CSV.
Did you test that scenario?
And second question:
You use Centos & SPDK as a nvme-of target. You use one NIC port to distribute a storage traffic.
Is it possible to use two NIC ports with two ip addresses for network redundancy?

With best regards,
Yury

You cannot create the HA mirror for StarWind NVMe-oF targets in the current version of the NVMe-oF Target. This feature is going to be introduced later.

Can I use that drive in clustered storage spaces for redundancy?

Yes, you can but this scenario was not tested by us.

Is it possible to use two NIC ports with two ip addresses for network redundancy?

This was not also tested by us.
