DescriptionCloud computing has developed high capacity, reliable
and economical storage systems based on object
technology. Los Alamos National Labs has designed the
storage systems for Trinity to include a cloud type
object storage system as a layer between the Parallel
File System (PFS). This pre-archive system has been
dubbed "Campaign Storage" with the purpose of storing
data products to be quickly accessible during the life
of a research project. Data stored on the Campaign
Storage can be pulled into the PFS or moved to archive
after the data has been curated. Campaign Storage
reduces the capacity requirements for PFS storage and
reduces the data transfer bandwidth requirements for the
archive storage.
We make these contributions to the pre-archive storage layer:
* GPU assisted erasure coding
* Demonstrating erasure on File Transfer Agents
* Reducing erasure recovery costs with "lazy recovery"
* Enabling larger erasure coded disk pools
