Enstore provides distributed access to and management of data stored on tape. It provides a generic interface so experimenters can efficiently use mass storage systems as easily as if they were native file systems.

DCache Systems
 
DCache provides disk-based front-end data buffering for the Enstore mass storage system. Files transferred to the dCache are written to the tape after a certain time limit or data accumulation, transparently to the user. When reading files from the dCache, users transparently access a file replica already in cache due to past activity or a file replica restored to cache from tape.

Recommendations Based on our experience with DCache. Your mileage may vary!
Operating System Scientific Linux 3.0.4 or later for all dCache hosts.
Kernel Versions Linux 2.4.21-32 or later; Linux 2.6.9-5 or later.
Data File System DCache data pools: XFS (use kernels with XFS support).
Java RTE/SDK Sun Java 1.4.2_08 or later. 1.5.0_03 works too, except krb5 auth.
