"In IBM's view, classical NAS is general purpose file storage that only allows capacity expansion behind one or two node clusters, making it most appropriate for the small to midrange market. Scalable NAS is the next step up," Hill said. "While it uses a single namespace to view all files, scalable NAS may well support limited node clustering for performance and capacity expansion, though its scaling is not necessarily linear or independent."
IBM said its SONAS array offers automated data tiering, meaning data can migrate between different disk drive types for higher or lower levels of performance based on preset policies.
"Every day, the equivalent of eight-times the information that exists in all US libraries combined is created," Doug Balog, vice president of disk systems for IBM, said in a statement. "Companies not only need to cost-effectively store that data, but they need to rapidly locate it and provide ubiquitous access to it instantly."
IBM said its policy-driven automation software for storage management can achieve increased utilization rates in file management systems, allowing a company to pre-define where data is placed, when it is created, where and when it moves to in the storage hierarchy, where it's copied for disaster recovery, and when it will be eventually deleted.
The company also said SONAS should reduce operational costs by consolidating hardware to reduce capital costs. "It also minimizes ongoing administration and headcount costs and decreases operational expenditures by streamlining and simplifying the administration, backup, application and access to data," IBM said.
