SUMMARY:The many uses of write off-loading - Dushyanth Narayanan (MSR Camb

DESCRIPTION:In the first part of this talk I will describe the technique o
 f write off-loading as used in Everest. Everest is a system designed to de
 al with short-term bursts in I/O load on servers in a data center. It allo
 ws data written to an overloaded volume to be temporarily off-loaded into 
 a short-term virtual store. Everest creates the short-term store by opport
 unistically pooling underutilized storage resources either on a server or 
 across servers within the data center. Writes are temporarily off-loaded f
 rom overloaded volumes to lightly loaded volumes\, thereby reducing the I/
 O load on the former. The technique is transparent and does not change the
  block device abstraction seen by applications and the OS.\n\nIn the secon
 d part of the talk I will describe more generally past\, ongoing\, and fut
 ure storage research at MSRC\, using write off-loading as a unifying theme
 . This includes our work on using off-loading to save energy\; on SSDs and
  their place in enterprise storage\; and on more general applications of t
 he write off-loading concept.\n\nBio: Dushyanth Narayanan is a researcher 
 at Microsoft's European research centre in Cambridge\, England. His curren
 t research focus is on storage systems. \n\nhttp://www.research.microsoft.
