Abstract: A system and method for determining I/O performance headroom that accounts for a real-world workload is provided. In some embodiments, a computing device is provided that is operable to identify a data transaction received by a storage system and directed to a storage device. The computing system identifies an attribute of the data transaction relating to a performance cost of the data transaction and queries a performance profile to determine a benchmark performance level for the storage device. The computing system determines a benchmark performance level for the storage system based on the benchmark performance level for the storage device and compares a metric of the performance of the data transaction with the storage system benchmark performance level to determine remaining headroom of the storage system.

Abstract: A system, method, and computer program product is described for providing dynamic enabling and/or disabling of protection information (PI) in array systems during operation. A storage system receives a request to transition a volume from PI disabled to PI enabled during regular operation. The storage system synchronizes and purges the cache associated with the target volume. The storage system initiates an immediate availability format (IAF-PI) process to initialize PI for the associated data blocks of the volume's storage devices. The storage system continues receiving I/O requests as the IAF-PI process sweeps through the storage devices. The storage system inserts and checks PI for the write data as it is written to the storage devices. The storage system inserts PI for requested data above the IAF-PI boundary and checks PI for requested data below the IAF-PI boundary. The transition remains an online process that avoids downtime.
