:) The positives are a much larger "randomly addressable" memory pool. The negatives are that its still flash (for the moment), and has all the issues associated with flash (random small writes == very bad). For read heavy workloads (in memory databases, etc.) its wonderful. For write heavy workloads, you'd want to make sure the devices were hot swappable (DIMMs aren't except in specific cases). -- Come by and visit us at SC13 in booth #1919 Joseph Landman, Ph.D Founder and CEO Scalable Informatics, Inc. email: land...@scalableinformatics.com web : http://scalableinformatics.com twtr : @scalablinfo phone: +1 734 786 8423 x121 cell : +1 734 612 4615 _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
