SUMMARY:Towards Physical Design Management in Storage Systems
DESCRIPTION:Workshop\n\nTowards Physical Design Management in Storage Syst
 ems\n\nDahlgren, LeFevre, Shirwadkar, Iizawa, Montana...\n\nIn the post-Mo
 ore era, systems and devices with new architectures will arrive at a rapid
  rate with significant impacts on the software stack. Applications will no
 t be able to fully benefit from new architectures unless they can delegate
  adapting to new devices to lower layers in the stack. In this paper we in
 troduce physical design management which deals with the problem of identif
 ying and executing transformations on physical designs of stored data -- i
 .e. how data is mapped to storage abstractions like files, objects, or blo
 cks -- in order to improve performance. Physical design is traditionally p
 laced with applications, access libraries, and databases, using hard-wired
  assumptions about underlying storage systems. Yet, storage systems increa
 singly not only contain multiple kinds of storage devices with vastly diff
 erent performance profiles but also move data among those storage devices,
  thereby changing the benefit of a particular physical design. We advocate
  placing physical design management in storage, identify interesting resea
 rch challenges, provide a brief description of a prototype implementation 
 in Ceph, and discuss the results of initial experiments at scale that are 
 digitally replicable using CloudLab. These experiments show performance an
 d resource utilization trade-offs associated with choosing different physi
 cal designs and choosing to transform between physical designs.\n\nTag: Wo
