ITaP maintains several different storage resources to accompany computational systems. Here is a brief introduction to research storage resources. More information and detailed documentation are available for each resource listed below.
The Fortress Archive (HPSS) system is a large, long-term, multi-tiered file caching and storage system utilizing both online disk and robotic tape drives. ITaP upgraded Fortress Archive (HPSS) from DXUL to HPSS in October of 2011.
Network Storage to all ITaP research resources comes from a combination of EMC Isilon and Data Direct Networks hardware. These provide multiple tiers of storage for three distinct classes of service:
- Individual's home directories,
- Software application space,
- Shared group space
- NFS scratch (Steele and Radon)
- Lustre parallel scratch (Peregrine 1, Coates, Rossmann, Hansen, Carter)
All Network Storage combined currently consists of more than 4 PB of redundant, high-availability disk space and is a central component of ITaP's research systems infrastructure.
