[lustre-discuss] R: OSS on compute node

[Fedele Stabile]

Thank you for the answer,
KVM is able  to use SR-IOV? 
What is the resource consumption (memory anc CPU) of a storage server?

There will be great risks to your storage and compute when sharing a node this way. However, we do this in development sandboxes where we have infrastructure as code to redeploy quickly and effortlessly when bad things happen. You should consider putting your Lustre nodes in KVMs, use SR-IOV and consider the impact of losing data. The resources on the storage node remaining may result in lower computing power, especially memory.
ZFS might be a better choice for your volumes.

Regards,
Walker

Hello everyone,
We are in progress to integrate Lustre on our little HPC Cluster and we would like to know if it is possible to use the same node in a cluster to act as an OSS with disks and to also use it as a Compute Node and then install a Lustre Client.
I know that the OSS server require a modified kernel so I suppose it can be installed in a virtual machine using kvm on a compute node.
