HI all, We are currently in the midst of planning a major refresh of our existing HPC cluster. It is expected that our storage will consist of a combination of fast fibre channel and SATA based disk and we would like to implement a system whereby user files are automatically migrated to and from slow storage depending on frequency of usage. Initial investigations seem to indicate that larger commercial hierarchical storage management systems vastly exceed our budget.
Is there any mature open source alternatives out there? How are other organisations dealing with transparently presenting different tiers of storage to non technical scientists? Cheers, Carl.
