guide:Dcache

The goal of this project is to provide a system for storing and retrieving huge amounts of data, distributed among a large number of heterogenous server nodes, under a single virtual filesystem tree with a variety of standard access methods.

Simplified dCache architecture

The dCache system consists of several components (nodes) which interact over the network

1. A provider site.
2. The user uses the SRM node for resources access, authentication, authorization to use the resources.
3. From SRM node user can access the PNFS node which know the data location, ADMIN node which works as the information system for dCache.
4. All connections need to pass the GridFTP Door, which acts as a generic interface to the pool of nodes, managed by the PNFS.
