Software RAID or hardware RAID: what’s better in 2023?

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.

Running Lustre on disaggregated storage with xiRAID

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.

The most efficient RAID for NVME drives

Since the introduction of NVMe SSD the question of RAID has been ever-present. Traditional technologies haven’t been able to scale proportionally to the speed increase of new devices, so most multi-drive installation relied on mirroring, sacrificing TCO benefits.
