Alps Storage¶
Alps has different storage attached, each with characteristics suited to different workloads and use cases. HPC storage is manged in a separate cluster of nodes that host servers that manage the storage and the physical storage drives. These separate clusters are on the same Slingshot 11 network as the Alps.

capstor¶
Capstor is the largest file system, for storing large amounts of input and output data. It is used to provide SCRATCH and STORE for different clusters - the precise details are platform-specific.
