Center for Parallell Computing - PDC Mass Storage Services PDC Mass Storage Services Introduction to Facilities and Operations Welcome as user of PDC Mass Storage Services , a collection of facilities for managing large amounts of data in the PDC environment. A Parallel File System for Strindberg enables high-performance file sharing between all SP nodes. Fast local scratch disk on all major system for temporary process-specific data. Enhanced AFS capacity.
Users benefit from enchaced performance, availability and storage capacity.
The change in residence for user files is transparent too because the files remain cataloged in their original directories and usually appear as if they were still on disk. When a file is migrated, its inode remains online, but the data is moved offline. A recall operation copies the file's data back online. The current HSM system runs on a SGI Onyx2 server. The system utilizes an IBM 3494 Tape Library Dataserver with four IBM 3590 Magstar tapedrives.
