Dell PowerScale overcomes the problems that undermine traditional NAS systems by combining the three traditional layers of storage architecture—file system, volume manager, and data protection—into a scale-out NAS cluster with a distributed file system. The Dell PowerScale architecture eliminates controller bottlenecks to reduce wall-clock runtimes for concurrent jobs. PowerScale accelerates metadata operations, improves storage efficiency to lower capital expenditures, centralizes management to reduce operating expenses, and delivers strategic advantages to increase competitiveness in a global market.
