  abstract = {The paper presents an analytical model of a whole disk array
  architecture, XDAC, which consists of several major subsystems and features:
  the two-dimensional array structure; IO-bus with split transaction protocol;
  and cache for processing multiple I/O requests in parallel. Our modelling
  approach is based on a subsystem access time per request (SATPR) concept, in
  which we model for each subsystem the mean access time per disk array
  request. The model is fed with a given set of representative workload
  parameters and then used to conduct performance analysis for exploring the
  impact of fork/join synchronization as well as evaluating some architectural
  design issues of the XDAC system. Moreover, by comparing the SATPRs of
  subsystems, we can identify the bottleneck for performance improvements.}
