The IT Data Explosion Is Game Changing for Storage Requirements
Release Date:June 4, 2012
Data-intensive computing has been an integral part of high-performance computing (HPC) and other large datacenter workloads for decades, but recent developments have dramatically raised the stakes for system requirements — including storage resiliency. The storage systems of today's largest HPC systems often reach capacities of 15–30PB, not counting scratch disk, and feature thousands or tens of thousands of disk drives. Even in more mainstream HPC and enterprise datacenters, storage systems today may include hundreds of drives, with capacities often doubling every two to three years. With this many drives, normal failure rates can mean that a disk is failing somewhere in the system often enough to make MTTF a serious concern at the system level.
