High-Throughput Computing Storage
The High-Throughput Computing Storage (HTC Storage) service has been designed for researchers with a need for large amounts of long-term storage for computation, with cost as a primary consideration.
Storage is only available on the Lewis cluster and the Lewis login node via sftp/rsync and not intended for parallel computation.
- Storage is limited to DCL1 and DCL2 research data. Administrative, commercial, and personal data is prohibited.
- Storage is allocated in blocks and each storage block has its own quota mount point.
- Storage nodes are expanded in large increments (100TB). Depending on available capacity, requests for storage blocks may be delayed until a storage node is expanded.
- The storage blocks expire after 5 years. Users must either purchase another storage block and transfer data to the new storage node; transfer data to another system; or do nothing and the data will be destroyed. Users may request a hardship waiver to the CI Council for temporary storage. No automatic data migration services are provided and users are responsible for the data integrity of moved data.
- Storage block may be expanded depending on the available capacity of the storage node. The storage block will retain the same expiry date as the original block and cost of the expansion will be pro-rated.
- Storage is based on ZFS and provided on a single node and single volume basis with no high availability (HA)
- There are no backups of the data. The data storage system is resilient to multiple disk failures (parity) and we do our best to protect the data but are not responsible for any data loss. Snapshots are available and count towards storage block.
- Storage is transferable but is not refundable.
Storage blocks are prepaid in full in 10TB increments for 5 years. The FY17 rate is $1,200/10TB/60 months.
This service is intended for researchers with a need for large amounts of long-term storage for computation (not archiving) and is available to individual researchers, non-sponsored researchers, research groups, and sponsored research on all campuses.
