XOSTOR as shared storage for VDIs?
-
I am looking to setup shared storage for VMs and have bare metal servers hosted with OVH Cloud however, unfortunately OVH does not allow block storage with bare metal servers.
I have been looking for a shared storage solution and I just discovered XOSTOR and have a few questions
Q1) If I order my bare metal servers with additional NVMe disks can I use these disks together as type of shared storage for the VM VDIs?
Q2) Would the XOSTOR performance be acceptable for VDIs?
Q3) As I add new hosts to the pool can I add the new hosts additional disks to XOSTOR to dynamically increase the XOSTOR storage?

Hi,
- Yes, that's the point of XOSTOR. Creating a shared SR with local drives
- Very likely, especially with NVMe drives, read speed will be like using a local NVMe, so great perf
- Not dynamically but you can add more after, yes

Thank you.
Can disks be different sizes?
How does XOSTOR manage the scenario of a host going offline? Is there a type of RAID or similar?

Have you read the doc first? https://docs.xcp-ng.org/xostor/
This gives a nice overview on how it works
