December 19, 2022
RAID (redundant array of independent disks) is a technology that allows combining multiple disk drives into arrays or RAID volumes by spreading (striping) data across drives. RAID can be used to improve performance by taking advantage of several drives’ worth of throughput to access the dataset.

Parallel file systems are the heart of the most demanding HPC workloads. As the need for computing power grows, so does the complexity of storage systems. I/O becomes more intensive, complex, and interdependent.The performance of parallel file systems must meet the requirements of computing clusters, and there are technologies that help with this.
