Scalable Security for High Performance, Petascale Storage

Petabyte scale, high-performance parallel file systems often hold sensitive data and thus require security, but authentication and authorization have the potential to reduce performance dramatically because of the high number of clients and devices, data distribution across both clients and devices, and bursty and demanding workloads. Existing security protocols perform poorly in these environments because they do not scale well - the number of security operations is strongly tied to the number of devices and requests.
