      abstract     = {As illustrated by the IO500 ranking performance and
                      scalability of storage systems have improved dramatically in
                      the recent years. Most of these progresses are due to novel
                      hardware and architectures. The resulting solutions tend to
                      be more complex and harder to manage from an end-user
                      perspective. This work proposes to address simultaneously
                      the user experience and the performance issue. The solution
                      is based on DDN's Infinite Memory Engine (IME), an all Flash
                      distributed cache that sits between the compute nodes and
                      the parallel file system. IME delivers extreme performance
                      for bulk data and complex I/O patterns but does not
                      accelerate metadata traffic. To shield the end-user from the
                      additional complexity of dealing with an extra storage-tier,
                      IME accesses are embedded within SIONlib. SIONlib is a
                      parallel I/O library, which has the ability to provide a
                      task local like access scheme for a single file in the
                      underlying file system that allows to reduce the number of
                      metadata operations. This combined construction with IME and
                      SIONlib allows end-users to obtain the Flash level of
                      performance transparently for their applications and also to
                      receive a performance boost on metadata operations. In
                      respect of traditional file systems, according to the
                      partest benchmark suite, the solution improves performance
                      over 1.8 times on a single node and up to 4 times for
                      multiple nodes. Moreover, experimenting with SIONlib
                      parameters we observe that the resulting performances are
                      more robust towards different data layout patterns and
                      transfer sizes than with traditional file systems.},
