Parallel file systems were developed to overcome delays servers experienced when accessing files on disk storage systems. Flash arrays get rid of disk access latencies and so weaken the need for parallel file systems. Spectrum Scale, the renamed GPFS (General Parallel File System) and Lustre are two such parallel file systems. Disk arrays are good at streaming IO but poor at random IO as these involve more disk seeks. In an interview with the Next Platform, Pure Storage’s Max Kixmoeller, its VP for products, said Pure wanted to bypass parallel file systems, which involve extra layers of code on top of an underlying file or object system, and have the applications in accessing servers connect directly with the underlying file/object system on a Pure FlashBlade array. He said a base line with NFS is a good starting point. Learn more at http://www.theregister.co.uk/2016/08/01/everyday_hpc_hasta_la_vista_lustre_so_long_spectrum_scale/
