Understanding I/O performance behavior is crucial to optimize I/O-intensive applications but also the infrastructure of data centers. However, with the dawn of new technologies such as NVRAM, burst-buffers, active storage/function shipping, and network attached memory, the complexity of storage infrastructure increases significantly and the boundary between memory and storage blurs. During the procurement of new systems, data centers have to ensure that the application's needs are met. Therefore, they need to define the proper requirements for storage and provide I/O benchmarks that represent application workloads to quantify and verify I/O performance.
The main goal of the workshop is the discussion of tools to identify (in-)efficient usage of I/O resources on modern storage subsystems from the perspective of users and data centers.
The workshop covers:
The discussion of alternative storage architectures lays the foundation for the requirements of the monitoring and benchmarking efforts. Speakers involved in storage and file system research will present experience in alternative storage architectures, application workflows, monitoring tools to identify bottlenecks in I/O, and (benchmarking) tools to quantify I/O performance. Scientists involved in various application domains can give an introduction to their workflows and I/O requirements.
By bringing together application developers/users and I/O experts, we support the development of tools to identify and quantify I/O inefficiencies that support users and data centers.

To participate, please register online (the deadline is now over). Alternatively, you may send an email to firstname.lastname@example.org. The deadline for registration is Feb. 25th. Note that our seats are limited and we have to confirm your attendance (you may also kindly ask about the status).
Within walking distance, we recommend the: Mercure Hotel Hamburg Mitte
Address: Schroederstiftstr. 3, 20146 Hamburg - Rotherbaum, Deutschland
DKRZ has a customer ID that we can provide to you upon request; this should give you a condition of 79€ per night.
The workshop is scheduled for a duration of one day, with discussion time between talks – directly followed by another workshop (to be announced). It is intended to use the workshop to foster the international collaboration for the IO-500 list, i.e., the definition of a meaningful I/O benchmark for tracking storage performance for current and future systems.
The Agenda is currently in preparation.
