Is there any way to > make efficient use of ~1TB cache partitions? How much RAM do these systems have? Each cache item requires some amount of ram to keep track of it. There is a balancing act of cache partition size to ram usage. Going from 200GB -> 1TB of cache will require >5x the RAM usage to maintain the cache. > Volkmar -derek -- Derek Atkins, SB '93 MIT EE, SM '95 MIT Media Laboratory Member, MIT Student Information Processing Board (SIPB) URL: http://web.mit.edu/warlord/ PP-ASEL-IA N1NWH warl...@mit.edu PGP key available _______________________________________________ OpenAFS-info mailing list OpenAFS-info@openafs.org https://lists.openafs.org/mailman/listinfo/openafs-info
