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:
There are currently three types of network storage used on ITaP research resources:
/home, /apps, and /group are examples of persistent storage spaces on ITaP research clusters.
Important: Persistent storage is not designed nor intended for use as high-performance working space for running jobs.
For scratch storage, each cluster is assigned a default Lustre parallel filesystem. The Lustre filesystems provide working storage optimized for a wide variety of job types, and are designed to perform well with data-itensive computations, while scaling well to large numbers of simultaneous connections.
All scratch tier resources are high-performance, large capacity, and subject to scheduled purging of old files.
The following ITaP research policies are particularly related to Network Storage:
