System at Oak Ridge
• 672 OSTs• 10 Petabytes of storage• 60 GB/sec = 480 Gbps aggregate performance (theoretical)• 225,000 compute cores
Prior Work
• Driver-level work for disk access• System-level strategies for effective buffering• Alternative file organizations (striping as Lustre)• Novel method
data staging alternative file formats or organizations better ways to organize and update file metadata
Adaptive I/O
• Dynamic and proactive methods for managing IO interference
shift work from heavily used areas of the storage system to those that are more lightly loaded.
