In this video from LUG 2015 in Denver, Robert Read from Intel presents: Lustre HSM in the Cloud.
The combination of the ephemeral nature of the cloud and directly addressable archives such as S3 suggest novel methods for using the Lustre HSM interface. Persistent data sets in the cloud need to be managed independently from an ephemeral filesystem and compute resources. Managing datasets in the cloud could, for example, involves importing data from Amazon’s S3 back into a freshly-created Lustre filesystem, performing I/O intensive computations, and then persisting the datasets back to S3 before terminating the filesystem and compute resources. Alternatives for archive formats will also be discussed. AWS S3 will be used for concrete examples, but the general methods should be applicable to other cloud environments as well.”
